Per capita income
Per capita income or average income measures the average income earned per person in a given area in a specified year. It is calculated by dividing the area's total income by its total population. Per capita income is national income divided by population size. Per capita income is used to measure an area's average income and compare the wealth of different populations. Per capita income is used to measure a country's standard of living, it is expressed in terms of a used international currency such as the euro or United States dollar, is useful because it is known, is calculable from available gross domestic product and population estimates, produces a useful statistic for comparison of wealth between sovereign territories. This helps to ascertain a country's development status, it is one of the three measures for calculating the Human Development Index of a country. In the United States, it is defined by the U. S. Census Bureau as the following: "Per capita income is the mean money income received in the past 12 months computed for every man and child in a geographic area."
Critics claim that per capita income has several weaknesses in measuring prosperity: Comparisons of per capita income over time need to consider inflation. Without adjusting for inflation, figures tend to overstate the effects of economic growth. International comparisons can be distorted by cost of living differences not reflected in exchange rates. Where the objective is to compare living standards between countries, adjusting for differences in purchasing power parity will more reflect what people are able to buy with their money, it does not reflect income distribution. If a country's income distribution is skewed, a small wealthy class can increase per capita income while the majority of the population has no change in income. In this respect, median income is more useful when measuring of prosperity than per capita income, as it is less influenced by outliers. Non-monetary activity, such as barter or services provided within the family, is not counted; the importance of these services varies among economies.
Per capita income does not consider whether income is invested in factors to improve the area's development, such as health, education, or infrastructure.

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
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 ZIP Code is a postal code used by the United States Postal Service in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; the basic format consists of five digits. An extended ZIP+4 code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location; the term ZIP Code was registered as a servicemark by the U. S. Postal Service, but its registration has since expired; the early history and context of postal codes began with postal district/zone numbers. The United States Post Office Department implemented postal zones for numerous large cities in 1943. For example: The "16" was the number of the postal zone in the specific city. By the early 1960s, a more organized system was needed, non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963; the USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with the list of two-letter state abbreviations which are written with both letters capitalized.
An earlier list in June had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59, the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by a long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska, changed from NB to NE in 1969 at the request of the Canadian postal administration, to avoid confusion with the Canadian province of New Brunswick. Robert Moon is considered the father of the ZIP Code; the post office only credits Moon with the first three digits of the ZIP Code, which describe the sectional center facility or "sec center." An SCF is a central mail processing facility with those three digits. The fourth and fifth digits, which give a more precise locale within the SCF, were proposed by Henry Bentley Hahn Sr.
The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, most of their employees work the night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits coincide with the older postal zone number thus: In 1967, these became mandatory for second- and third-class bulk mailers, the system was soon adopted generally; the United States Post Office used a cartoon character, which it called Mr. ZIP, to promote the use of the ZIP Code, he was depicted with a legend such as "USE ZIP CODE" in the selvage of panes of postage stamps or on the covers of booklet panes of stamps. In 1971 Elmira Star-Gazette reporter Dick Baumbach found out the White House was not using a ZIP Code on its envelopes.
Herb Klein, special assistant to President Nixon, responded by saying the next printing of envelopes would include the ZIP Code. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4 called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, initial attempts to promote universal use of the new format met with public resistance and today the plus-four code is not required. In general, mail is read by a multiline optical character reader that instantly determines the correct ZIP+4 Code from the address—along with the more specific delivery point—and sprays an Intelligent Mail barcode on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point.
For Post Office Boxes, the general rule is. The add-on code is one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box; the ZIP Code is translated into an Intelligent Mail barcode, printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender, it is better to let the post office put one on. In general, the post office uses OCR technology, though in some cases a human might have to read and enter the address. Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mai
Mobile County Public School System
Mobile County Public School System is a school district based in unincorporated Mobile County, United States. The system serves areas of Mobile County, including the city of Mobile, with the exception of the cities of Saraland and Chickasaw. Saraland voted to separate its schools from Mobile County in 2006, with Satsuma and Chickasaw following suit in 2012; the system serves urban and rural areas. All schools in the system are required to adopt school uniform policies, it is the 71st largest school system in the United States. The current Mobile County Public School System can trace its beginnings to the Board of School Commissioners of Mobile County, created by the Alabama Legislature through an act passed on January 10, 1826; this was the first education board created in Alabama. The act to establish the board was introduced by a legislator from Mobile; the first school building built by the board, Barton Academy, was named in his honor. It was built in the block between Government, Cedar and Lawrence Streets, purchased by this first board for $2750 in 1830.
Lack of funding stalled progress on the project until an act was passed in the state legislature that allowed the commissioners to raise funds through a lottery. By early 1836 the board had managed to pull together $50,000 in lottery funds, a $15,000 municipal loan, additional private donations with which to commence building a school; this included a large private donation from local millionaire Henry Hitchcock, on the building committee. Construction commenced on February 13, 1836 and, after several delays, was completed in January 1839. Following completion of Barton Academy, the Board of School Commissioners of Mobile County allowed the building to be used for private and denominational schools, with some funding appropriated to them by the commissioners. An act in 1846 allowed for taxes to be collected for the establishment of a free Methodist school by the commission; the commission was behind another act on February 9, 1852 that would have allowed the commission to sell the building, now in need of maintenance and repairs, distribute the proceeds among the existing schools, if approved by the voters.
The electorate subsequently elected a new board of commissioners. After the election of the new board, the building was repaired and the system was reorganized; the building reopened as a public school in November 1852. The school was closed for the duration of the American Civil War; the Girls High School reopened in 1865, followed by the Boys High School in 1870. Both would continue at Barton until the opening of Murphy High School in 1926, it continued to serve as a school building until the 1960s when it was converted into the central office for the Mobile County Public School System. The school board relocated to a new central office complex in 2007, leaving the historic building vacant; the Barton Academy building was added to Alabama Historical Commission's "Places in Peril" list in 2009. In 1963 three African-American students brought a case against the Mobile County School Board for being denied admission to Murphy High School; the court ordered that the three students be admitted to Murphy for the 1964 school year, leading to the desegregation of Mobile County's school system.
The Civil Rights Movement led to the end of legal racial segregation with passage of the Civil Rights Act of 1964. In 1983 there were allegations that the Mobile County school board deliberately ignored an injunction against prayer led by teachers, but that year, Lewis F. Powell, a member of the United States Supreme Court, declined not to bring contempt proceedings against the district's board. Though, the schools were ordered to stop mandating school prayer on a permanent basis by the U. S. Supreme Court in Wallace v. Jaffree. In 1987, there was another lawsuit alleging that secular humanism was being promoted but this claim was rejected in Smith v. Board of School Commissioners of Mobile County. In 1991 MCPSS was the largest school district in Alabama. In 1991 Governor of Alabama Guy Hunt announced that the state education budget would decrease by $145 million. Therefore, the MCPSS administration prepared for a possible closure. In 2001 superintendent Harold W. Dodge proposed removing all extracurricular activities from MCPSS schools in order to save $1.3 million.
This money funded supplemental salaries for people who do instruction for extracurricular activities, including American football programs. In 2013, the Southern Poverty Law Center won a permanent settlement with the school district that prohibits suspending students for violating the school uniform policy; as of 2012 the out-of-district tuition for Mobile County schools is $2,200 per student per year. As of 2011 the county school system had 60,946 students, making it the largest school district in Alabama; this was a decrease of 916 students from the previous school year, with a decrease in 502 students in the traditional county schools. Much of the remaining population loss resulted from the termination of a contract with Alternatives Unlimited Inc. an outside company, to operate Drop Back In Academy. As of 2011 schools east of Interstate 65 had more severe decreases in their student bodies than schools west of the interstate. There are 17 high schools operated by the MCPSS. There are 19 middle schools operated by the MCPSS.
There are 53 elementary schools operated by the MCPSS. Statewide testing ranks the schools in Alabama; those in the bottom six percent are listed as "failing." As of early 2018, nine local schools were included in this category: Ben C Rain High School Booker T Washington Middle School Mattie T Blount High School Mobile
Mobile County, Alabama
Mobile County is the second most-populous county in the U. S. state of Alabama. As of the 2010 census, its population was 412,992, its county seat is Mobile, founded on the Mobile River. The city and county were named in honor of the indigenous Maubila tribe. Mobile County comprises Alabama Metropolitan Statistical Area; this area was occupied for thousands of years by varying cultures of indigenous peoples. The historic Choctaw had occupied this area along what became called the Mobile River when encountered by early French traders and colonists, who founded Mobile in the early eighteenth century; the British took over the territory in 1763 after defeating the French in the Seven Years' War. During the American Revolutionary War, it came under Spanish rule as part of Spanish Florida. Spain ceded the territory to the United States after the War of 1812. In the 1830s, the United States forced the removal of most of the Native Americans in the area under President Andrew Jackson's policy to relocate them to Indian Territory west of the Mississippi River.
Many of those who remained continued their culture. Among those is the MOWA Band of Choctaw Indians, recognized as a tribe in 1979 by the state, but not federally. After more than a century of European settlement, Mobile County was organized by the legislature and the proclamation of Governor Holmes of the Mississippi Territory on December 18, 1812; when Mississippi was separated and admitted as a state on December 10, 1817, after adopting its constitution on August 15, 1817, Mobile County became part of what was called the Alabama Territory. Two years the county became part of the state of Alabama, granted statehood on December 14, 1819; the city of Mobile, first settled by French colonists in the early 18th century as part of La Louisiane, was designated as the county seat from the early days of the county. Both the county and city derive their name from Fort Louis de la Mobile, a French fortification established in 1702; the word "Mobile" is believed to stem from a Choctaw Indian word for "paddlers".
The area was occupied by French colonists from 1702 -- 1763. It was ruled by the British from 1763–1780, when more American colonists began to enter the territory. At the end of the War of 1812, the United States took over the territory. At that time, new settlers were being attracted to the land, eager to develop short-staple cotton in the uplands area. Invention of the cotton gin made processing of this type of cotton profitable, stimulating wholesale development of new cotton plantations in the Black Belt during the antebellum years. Mobile developed as a major port for export of cotton. There were nine documented lynchings in Mobile from 1891 to 1981. March 31, 1891 Zachariah Graham October 2, 1906 Roy Hoyle October 2, 1906 Willie Thompson October 2, 1906 Corneilius Robinson September 22, 1907 Mose Dossett January 23, 1909 Richard Robertson July 31, 1910 Bill Walker June 6th 1919 James E. Lewis March 21, 1981 Michael DonaldCourthouse fires occurred in the years 1823, 1840, 1872. According to the U.
S. Census Bureau, the county has a total area of 1,644 square miles, of which 1,229 square miles is land and 415 square miles is water, it second-largest by total area. It includes several islands, including Gaillard Island and Mon Louis Island. Washington County Baldwin County Jackson County, Mississippi George County, Mississippi Greene County, Mississippi Bon Secour National Wildlife Refuge Grand Bay National Wildlife Refuge According to the 2010 United States Census, the population of the county comprised the following racial and ethnic groups: 60.2% White 34.6% Black 0.9% Native American 1.8% Asian 0.0% Native Hawaiian or Pacific Islander 1.5% Two or more races 2.4% Hispanic or Latino According to the 2000 United States Census, there were 399,843 people, 150,179 households, 106,777 families residing in the county. The population density was 324 people per square mile. There were 165,101 housing units at an average density of 134 per square mile; the racial makeup of the county was 63.07% White, 33.38% Black or African American, 0.67% Native American, 1.41% Asian, 0.03% Pacific Islander, 0.40% from other races, 1.04% from two or more races.
1.22% of the population were Hispanic or Latino of any race. There were 150,179 households out of which 34.40% had children under the age of 18 living with them, 49.50% were married couples living together, 17.70% had a female householder with no husband present, 28.90% were non-families. 24.80% of all households were made up of individuals and 8.80% had someone living alone, 65 years of age or older. The average household size was 2.61 and the average family size was 3.13. In the county, the population dispersal was 27.50% under the age of 18, 10.00% from 18 to 24, 28.70% from 25 to 44, 21.90% from 45 to 64, 12.00% who were 65 years of age or older. The median age was 34 years. For every 100 females, there were 91.50 males. For every 100 females age 18 and over, there were 87.10 males. The median income for a household in the county was $33,710, the median income for a family was $40,378. Males had a median income of $32,329 versus $21,986 for females; the per capita income for the county was $17,178.
About 15.60% of families and 18.50% of the population were
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
