Calhoun County, Illinois
Calhoun County is a county in the U. S. state of Illinois. As of the 2010 census, the population was 5,089, its county seat and biggest community is Hardin, with a population of less than 1,000. Its smallest community is Hamburg, with a population of 123. Calhoun County is at the tip of the peninsula formed by the courses of the Mississippi and Illinois rivers above their confluence and is completely surrounded by water. Calhoun County is sparsely populated. Calhoun County is part of the Metro-East portion of the St. Louis, MO-IL Metropolitan Statistical Area; the territory was settled by indigenous people who occupied the resource-rich river valleys near waterways. The remains of their occupation have provided some of the most valuable archaeological information in the country; the county's archaeological record chronicles more than 10,000 years of continuous human occupation by Native Americans. Calhoun County was settled by Americans during the 19th century, organized in 1825, it was named for Vice President John C.
Calhoun, in addition to the Calhoun family, prominent in the area at the time. The southern side of the county, covered in thick forest, was untouched until the population began to expand in the late 1840s with the arrival of German immigrants. Land was cleared for farming, exporting lumber, constructing spacious log barns 200 square feet in size, which were a "trademark of successful German farmers."The most well-known historical event to impact Calhoun County is the Great Flood of 1993. Calhoun County is a peninsula nestled between the Illinois and Mississippi Rivers, which both saw record flooding during 1993; the Great Flood of 1993, the name it is now known as, impacted several villages in Calhoun and destroyed the village of East Hardin which once sat across the Joe Page Bridge when a levee broke in August 1993. The flood closed all crossings over the rivers in the county including the bridge in Hardin and all ferries, leaving residents without access to groceries, gasoline, or other supplies.
All supplies needed had to be flown in via helicopter or retrieved on a 2 hour long drive north via the only road existing Calhoun without a water passage or was not covered by flood water. The Great Flood of 1993 was devastating to Calhoun County because it destroyed homes and caused many residents to leave; the population of the county has yet to recover. According to the U. S. Census Bureau, the county has a total area of 284 square miles, of which 254 square miles is land and 30 square miles is water. Calhoun County is a narrow 37-mile -long peninsula of high, rolling ground located between the Mississippi River and the Illinois River; the rolling hills escaped the leveling of glaciers. County transportation is served by two free ferries crossing the Illinois River; the Golden Eagle ferry, operated and charges a toll, crosses the Mississippi River to St. Charles County, Missouri. A bridge spans the Illinois River at Hardin. Land routes connect to the north to bordering Pike County; when transportation was by river, the county had many prosperous farms and orchards.
It still produces a major portion of the peach crop of Illinois, farmers raise corn and other commodities. The hotel in Brussels dates from 1847. Tourists visit the area for the natural environment of the Illinois River valley and for its proximity to the Great River Road on the Illinois side, it includes part of the Two Rivers National Wildlife Refuge and attracts thousands of birds in migration seasons as part of the Mississippi Flyway. The county has several designated historic districts in the villages and properties listed on the National Register of Historic Places. Calhoun County was added to the St. Louis Metropolitan Statistical Area in 2003, along with Bond and Macoupin counties in Illinois, Washington County, Missouri; the Center for American Archeology is located in Kampsville in the northern part of the county. It has been the center for study of prehistoric indigenous culture in the area, it has created educational opportunities for children and adults to participate in its archaeological digs.

Average monthly precipitation ranged from 2.01 inches in January to 4.10 inches in May. In the 2000 census, there were no African-Americans living in the county, leading to James Leuwen designating it a "sundown town"; as of the 2010 census, there were 5,089 people, 2,085 households, 1,447 families residing in the county. The population density was 20.0 inhabitants per square mile. There were 2,835 housing units at an average density of 11.2 per square mile.
The racial makeup of the county was 98.9% white, 0.2% Asian, 0.2% American Indian, 0.1% black or African American, 0.2% from other races, 0.4% from two or more races. Those of Hispanic or Latino origin made up 0.8% of the population. In terms of ancestry, 46.2% were German, 14.7% were American, 12.4% were Irish, an
Clinton County, Illinois
Clinton County is a county located in the U. S. state of Illinois. As of the 2010 United States Census, the population was 37,762, its county seat is Carlyle. In 1960, the United States Census Bureau placed the mean center of U. S. population in Clinton County. Clinton County is part of MO-IL Metropolitan Statistical Area. In 1805, prior to the establishment of the county, the territorial government established a post road from its capital to St. Louis, passing through the county. In 1808 a wagon road was laid out through the future Clinton County, it extended from the Goshen Settlement to the Ohio salt works and crossed the Kaskaskia River at Carlyle. Clinton County was created on 27 December 1824, from portions of Washington and Bond Counties, it was named for the seventh Governor of DeWitt Clinton, who helped build the Erie Canal. Crossing the Kaskaskia became much easier when the bridge now known as the General Dean Suspension Bridge was built in 1859, at a cost of $40,000. Before the bridge was constructed, crossings involved a mud bridge.
The Illinois General Assembly set aside $20,000 for bridge restoration in 1951, in 1953 the bridge was named after William F. Dean. According to the U. S. Census Bureau, the county has a total area of 503 square miles, of which 474 square miles is land and 29 square miles is water. Eldon Hazlet State Recreation Area and South Shore State Park are in Clinton County, its southern border is the Kaskaskia River. In recent years, average temperatures in the county seat of Carlyle have ranged from a low of 19 °F in January to a high of 88 °F in July, although a record low of −22 °F was recorded in January 1994 and a record high of 104 °F was recorded in July 1980. Average monthly precipitation ranged from 2.17 inches in January to 4.44 inches in June. As of the 2010 United States Census, there were 37,762 people, 14,005 households, 9,760 families residing in the county; the population density was 79.7 inhabitants per square mile. There were 15,311 housing units at an average density of 32.3 per square mile.
The racial makeup of the county was 93.4% white, 3.5% black or African American, 0.4% Asian, 0.2% American Indian, 1.2% from other races, 1.1% from two or more races. Those of Hispanic or Latino origin made up 2.8% of the population. In terms of ancestry, 54.8% were German, 9.8% were Irish, 5.8% were English, 5.6% were American. Of the 14,005 households, 32.7% had children under the age of 18 living with them, 56.5% were married couples living together, 8.7% had a female householder with no husband present, 30.3% were non-families, 25.1% of all households were made up of individuals. The average household size was 2.55 and the average family size was 3.02. The median age was 39.3 years. The median income for a household in the county was $55,278 and the median income for a family was $66,682. Males had a median income of $45,119 versus $34,051 for females; the per capita income for the county was $25,392. About 5.2% of families and 7.8% of the population were below the poverty line, including 9.2% of those under age 18 and 5.7% of those age 65 or over.
As part of German Catholic Central Illinois, nineteenth-century Clinton County was opposed to the “Yankee” Civil War and the Northern Illinois residents who supported it and the Republican Party. The county was solidly Democratic for the six decades after the Civil War, turning Republican only due to opposition to Woodrow Wilson’s post-World War I policies towards Germany, its first flirt with Republicanism was short-lived: in 1924 Clinton was the nation's southeasternmost county – and the solitary one in Illinois – to give a plurality to Robert M. La Follette Sr. and in 1928 its residents voted powerfully for coreligionist Al Smith despite a landslide loss nationally. 1936, despite a landslide win for Franklin D. Roosevelt, saw Clinton County, like many other German Catholic counties in the Midwest, show a more permanent trend away from the Democratic Party: owing to a strong vote for Union Party candidate William Lemke, Roosevelt only won a plurality, with powerful local opposition to World War II Wendell Willkie and Thomas E. Dewey won over 62 percent of the county's vote in the two elections held whilst World War II was in progress.
Since only Catholic John F. Kennedy and Lyndon B. Johnson during his 1964 landslide have obtained a majority in the county for the Democratic Party, although county namesake Bill Clinton did win pluralities in both 1992 and 1996. Since 2000, opposition to the Democratic Party's liberal views on social issues has caused a powerful swing towards the Republican Party: Donald Trump won the county against namesake Hillary Clinton by 48.6 percent in 2016 – the worst performance by a Democrat.

Race and ethnicity in the United States Census
Race and ethnicity in the United States Census, defined by the federal Office of Management and Budget and the United States Census Bureau, are self-identification data items in which residents choose the race or races with which they most identify, indicate whether or not they are of Hispanic or Latino origin. The racial categories represent a social-political construct for the race or races that respondents consider themselves to be and, "generally reflect a social definition of race recognized in this country." OMB defines the concept of race as outlined for the US Census as not "scientific or anthropological" and takes into account "social and cultural characteristics as well as ancestry", using "appropriate scientific methodologies" that are not "primarily biological or genetic in reference." The race categories include both national-origin groups. Race and ethnicity are considered separate and distinct identities, with Hispanic or Latino origin asked as a separate question. Thus, in addition to their race or races, all respondents are categorized by membership in one of two ethnic categories, which are "Hispanic or Latino" and "Not Hispanic or Latino".
However, the practice of separating "race" and "ethnicity" as different categories has been criticized both by the American Anthropological Association and members of US Commission on Civil Rights. In 1997, OMB issued a Federal Register notice regarding revisions to the standards for the classification of federal data on race and ethnicity. OMB developed race and ethnic standards in order to provide "consistent data on race and ethnicity throughout the Federal Government; the development of the data standards stem in large measure from new responsibilities to enforce civil rights laws." Among the changes, OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of interracial children and wanting to capture the diversity in a measurable way and having received requests by people who wanted to be able to acknowledge their or their children's full ancestry rather than identifying with only one group. Prior to this decision, the Census and other government data collections asked people to report only one race.
The OMB states, "many federal programs are put into effect based on the race data obtained from the decennial census. Race data are critical for the basic research behind many policy decisions. States require these data to meet legislative redistricting requirements; the data are needed to monitor compliance with the Voting Rights Act by local jurisdictions". "Data on ethnic groups are important for putting into effect a number of federal statutes. Data on Ethnic Groups are needed by local governments to run programs and meet legislative requirements." The 1790 United States Census was the first census in the history of the United States. The population of the United States was recorded as 3,929,214 as of Census Day, August 2, 1790, as mandated by Article I, Section 2 of the United States Constitution and applicable laws."The law required that every household be visited, that completed census schedules be posted in'two of the most public places within, there to remain for the inspection of all concerned...' and that'the aggregate amount of each description of persons' for every district be transmitted to the president."
This law along with U. S. marshals were responsible for governing the census. One third of the original census data has been lost or destroyed since documentation; the data was lost in 1790–1830 time period and included data from: Connecticut, Maryland, New Hampshire, New York, North Carolina, Rhode Island, South Carolina, Delaware, New Jersey, Virginia. Census data included the name of the head of the family and categorized inhabitants as follows: free white males at least 16 years of age, free white males under 16 years of age, free white females, all other free persons, slaves. Thomas Jefferson the Secretary of State, directed marshals to collect data from all thirteen states, from the Southwest Territory; the census was not conducted in Vermont until 1791, after that state's admission to the Union as the 14th state on March 4 of that year. There was some doubt surrounding the numbers, President George Washington and Thomas Jefferson maintained the population was undercounted; the potential reasons Washington and Jefferson may have thought this could be refusal to participate, poor public transportation and roads, spread out population, restraints of current technology.
No microdata from the 1790 population census is available, but aggregate data for small areas and their compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System. In 1800 and 1810, the age question regarding free white males was more detailed; the 1820
A census is the procedure of systematically acquiring and recording information about the members of a given population. The term is used in connection with national population and housing censuses; the United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory and defined periodicity", recommends that population censuses be taken at least every 10 years. United Nations recommendations cover census topics to be collected, official definitions and other useful information to co-ordinate international practice; the word is of Latin origin: during the Roman Republic, the census was a list that kept track of all adult males fit for military service. The modern census is essential to international comparisons of any kind of statistics, censuses collect data on many attributes of a population, not just how many people there are. Censuses began as the only method of collecting national demographic data, are now part of a larger system of different surveys.
Although population estimates remain an important function of a census, including the geographic distribution of the population, statistics can be produced about combinations of attributes e.g. education by age and sex in different regions. Current administrative data systems allow for other approaches to enumeration with the same level of detail but raise concerns about privacy and the possibility of biasing estimates. A census can be contrasted with sampling in which information is obtained only from a subset of a population. Modern census data are used for research, business marketing, planning, as a baseline for designing sample surveys by providing a sampling frame such as an address register. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling. Stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations. In some countries, the census provides the official counts used to apportion the number of elected representatives to regions.
In many cases, a chosen random sample can provide more accurate information than attempts to get a population census. A census is construed as the opposite of a sample as its intent is to count everyone in a population rather than a fraction. However, population censuses rely on a sampling frame to count the population; this is the only way to be sure that everyone has been included as otherwise those not responding would not be followed up on and individuals could be missed. The fundamental premise of a census is that the population is not known and a new estimate is to be made by the analysis of primary data; the use of a sampling frame is counterintuitive as it suggests that the population size is known. However, a census is used to collect attribute data on the individuals in the nation; this process of sampling marks the difference between historical census, a house to house process or the product of an imperial decree, the modern statistical project. The sampling frame used by census is always an address register.
Thus it is not known how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, an enumerator calls, or administrative records for the dwelling are accessed; as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, this can be out of date and some dwellings may contain a number of independent households. A particular problem is what are termed'communal establishments' which category includes student residences, religious orders, homes for the elderly, people in prisons etc; as these are not enumerated by a single householder, they are treated differently and visited by special teams of census workers to ensure they are classified appropriately. Individuals are counted within households and information is collected about the household structure and the housing. For this reason international documents refer to censuses of housing.
The census response is made by a household, indicating details of individuals resident there. An important aspect of census enumerations is determining which individuals can be counted from which cannot be counted. Broadly, three definitions can be used: de facto residence; this is important to consider individuals who have temporary addresses. Every person should be identified uniquely as resident in one place but where they happen to be on Census Day, their de facto residence, may not be the best place to count them. Where an individual uses services may be more useful and this is at their usual, or de jure, residence. An individual may be represented at a permanent address a family home for students or long term migrants, it is necessary to have a precise definition of residence to decide whether visitors to a country should be included in the population count. This is becoming more important as students travel abroad for education for a period of several years. Other groups causing problems of enumeration are new born babies, people away on holiday, people moving home around census day, people without a fixed address.
People having second homes because of working in another part of the country or retaining a holiday cottage are dif
Marriage called matrimony or wedlock, is a or ritually recognised union between spouses that establishes rights and obligations between those spouses, as well as between them and any resulting biological or adopted children and affinity. The definition of marriage varies around the world not only between cultures and between religions, but throughout the history of any given culture and religion, evolving to both expand and constrict in who and what is encompassed, but it is principally an institution in which interpersonal relationships sexual, are acknowledged or sanctioned. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity; when defined broadly, marriage is considered a cultural universal. A marriage ceremony is known as a wedding. Individuals may marry for several reasons, including legal, libidinal, financial and religious purposes. Whom they marry may be influenced by gender determined rules of incest, prescriptive marriage rules, parental choice and individual desire.
In some areas of the world, arranged marriage, child marriage and sometimes forced marriage, may be practiced as a cultural tradition. Conversely, such practices may be outlawed and penalized in parts of the world out of concerns of the infringement of women's rights, or the infringement of children's rights, because of international law. Around the world in developed democracies, there has been a general trend towards ensuring equal rights within marriage for women and recognizing the marriages of interfaith and same-sex couples; these trends coincide with the broader human rights movement. Marriage can be recognized by a state, an organization, a religious authority, a tribal group, a local community, or peers, it is viewed as a contract. When a marriage is performed and carried out by a government institution in accordance with the marriage laws of the jurisdiction, without religious content, it is a civil marriage. Civil marriage recognizes and creates the rights and obligations intrinsic to matrimony before the state.
When a marriage is performed with religious content under the auspices of a religious institution it is a religious marriage. Religious marriage recognizes and creates the rights and obligations intrinsic to matrimony before that religion. Religious marriage is known variously as sacramental marriage in Catholicism, nikah in Islam, nissuin in Judaism, various other names in other faith traditions, each with their own constraints as to what constitutes, who can enter into, a valid religious marriage; some countries do not recognize locally performed religious marriage on its own, require a separate civil marriage for official purposes. Conversely, civil marriage does not exist in some countries governed by a religious legal system, such as Saudi Arabia, where marriages contracted abroad might not be recognized if they were contracted contrary to Saudi interpretations of Islamic religious law. In countries governed by a mixed secular-religious legal system, such as in Lebanon and Israel, locally performed civil marriage does not exist within the country, preventing interfaith and various other marriages contradicting religious laws from being entered into in the country, civil marriages performed abroad are recognized by the state if they conflict with religious laws.
The act of marriage creates normative or legal obligations between the individuals involved, any offspring they may produce or adopt. In terms of legal recognition, most sovereign states and other jurisdictions limit marriage to opposite-sex couples and a diminishing number of these permit polygyny, child marriages, forced marriages. In modern times, a growing number of countries developed democracies, have lifted bans on and have established legal recognition for the marriages of interfaith and same-sex couples; some cultures allow the dissolution of marriage through annulment. In some areas, child marriages and polygamy may occur in spite of national laws against the practice. Since the late twentieth century, major social changes in Western countries have led to changes in the demographics of marriage, with the age of first marriage increasing, fewer people marrying, more couples choosing to cohabit rather than marry. For example, the number of marriages in Europe decreased by 30% from 1975 to 2005.
In most cultures, married women had few rights of their own, being considered, along with the family's children, the property of the husband. In Europe, the United States, other places in the developed world, beginning in the late 19th century and lasting through the 21st century, marriage has undergone gradual legal changes, aimed at improving the rights of the wife; these changes included giving wives legal identities of their own, abolishing the right of husbands to physically discipline their wives, giving wives property rights, liberalizing divorce laws, providing wives with reproductive rights of their own, requiring a wife's consent when sexual relations occur. These changes have occurred in Western countries. In the 21st century, there continue to be controversies regarding the legal status of married women, legal acceptance of or leniency towards violence within marriage, traditional marriage customs such as dowry and bride price, for
United States Census Bureau
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy; the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States; the Census Bureau's primary mission is conducting the U. S. Census every ten years, which allocates the seats of the U. S. House of Representatives to the states based on their population; the Bureau's various censuses and surveys help allocate over $400 billion in federal funds every year and it helps states, local communities, businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, transportation infrastructure, police and fire departments. In addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, the Current Population Survey.
Furthermore and foreign trade indicators released by the federal government contain data produced by the Census Bureau. Article One of the United States Constitution directs the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the House of Representatives and, by extension, in the Electoral College; the Census Bureau now conducts a full population count every 10 years in years ending with a zero and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population projections. In addition, Census data directly affects how more than $400 billion per year in federal and state funding is allocated to communities for neighborhood improvements, public health, education and more; the Census Bureau is mandated with fulfilling these obligations: the collecting of statistics about the nation, its people, economy. The Census Bureau's legal authority is codified in Title 13 of the United States Code.
The Census Bureau conducts surveys on behalf of various federal government and local government agencies on topics such as employment, health, consumer expenditures, housing. Within the bureau, these are known as "demographic surveys" and are conducted perpetually between and during decennial population counts; the Census Bureau conducts economic surveys of manufacturing, retail and other establishments and of domestic governments. Between 1790 and 1840, the census was taken by marshals of the judicial districts; the Census Act of 1840 established a central office. Several acts followed that revised and authorized new censuses at the 10-year intervals. In 1902, the temporary Census Office was moved under the Department of Interior, in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor; the department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their subordinate role in the department. An act in 1920 changed the date and authorized manufacturing censuses every two years and agriculture censuses every 10 years.
In 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code. By law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year; the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are "widely used...for data collection and analysis". The Census Bureau definition is pervasive. Regional divisions used by the United States Census Bureau: Region 1: Northeast Division 1: New England Division 2: Mid-Atlantic Region 2: Midwest Division 3: East North Central Division 4: West North Central Region 3: South Division 5: South Atlantic Division 6: East South Central Division 7: West South Central Region 4: West Division 8: Mountain Division 9: Pacific Many federal, state and tribal governments use census data to: Decide the location of new housing and public facilities, Examine the demographic characteristics of communities and the US, Plan transportation systems and roadways, Determine quotas and creation of police and fire precincts, Create localized areas for elections, utilities, etc.
Gathers population information every 10 years The United States Census Bureau is committed to confidentiality, guarantees non-disclosure of any addresses or personal information related to individuals or establishments. Title 13 of the U. S. Code establishes penalties for the disclosure of this information. All Census employees must sign an affidavit of non-disclosure prior to employment; the Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government
Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.
