2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits.

Time in the United States
Time in the United States, by law, is divided into nine standard time zones covering the states and its possessions, with most of the United States observing daylight saving time for the spring and fall months. The time zone boundaries and DST observance are regulated by the Department of Transportation. Official and precise timekeeping services are provided by two federal agencies: the National Institute of Standards and Technology; the clocks run by these services are kept synchronized with each other as well as with those of other international timekeeping organizations. It is the combination of the time zone and daylight saving rules, along with the timekeeping services, which determines the legal civil time for any U. S. location at any moment. Before the adoption of four standard time zones for the continental United States, many towns and cities set their clocks to noon when the sun passed their local meridian, pre-corrected for the equation of time on the date of observation, to form local mean solar time.
Noon occurred at different times but time differences between distant locations were noticeable prior to the 19th century because of long travel times and the lack of long-distance instant communications prior to the development of the telegraph. The use of local solar time became awkward as railways and telecommunications improved. American railroads maintained many different time zones during the late 1800s; each train station set its own clock making it difficult to coordinate train schedules and confusing passengers. Time calculation became a serious problem for people traveling by train, according to the Library of Congress; every city in the United States used a different time standard so there were more than 300 local sun times to choose from. Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Railroad managers tried to address the problem by establishing 100 railroad time zones, but this was only a partial solution to the problem.
Weather service chief Cleveland Abbe had needed to introduce four standard time zones for his weather stations, an idea which he offered to the railroads. Operators of the new railroad lines needed a new time plan that would offer a uniform train schedule for departures and arrivals. Four standard time zones for the continental United States were introduced at noon on November 18, 1883, when the telegraph lines transmitted time signals to all major cities. In October 1884, the International Meridian Conference at Washington DC adopted a proposal which stated that the prime meridian for longitude and timekeeping should be one that passes through the centre of the transit instrument at the Greenwich Observatory in the United Kingdom; the conference therefore established the Greenwich Meridian as the prime meridian and Greenwich Mean Time as the world's time standard. The US time-zone system grew from this, in which all zones referred back to GMT on the prime meridian. In 1960, the International Radio Consultative Committee formalized the concept of Coordinated Universal Time, which became the new international civil time standard.
UTC is, within about 1 second, mean solar time at 0°. UTC does not observe daylight saving time. For most purposes, UTC is considered interchangeable with GMT, but GMT is no longer defined by the scientific community. UTC is one of several related successors to GMT. Standard time zones in the United States are defined at the federal level by law 15 USC §260; the federal law establishes the transition dates and times at which daylight saving time occurs, if observed. It is the authority of the Secretary of Transportation, in coordination with the states, to determine which regions will observe which of the standard time zones and if they will observe daylight saving time; as of August 9, 2007, the standard time zones are defined in terms of hourly offsets from UTC. Prior to this they were based upon the mean solar time at several meridians 15° apart west of Greenwich. Only the full-time zone names listed below are official. View the standard time zone boundaries here; the United States uses nine standard time zones.
As defined by US law they are: From east to west, the four time zones of the contiguous United States are: Eastern Time Zone, which comprises the states on the Atlantic coast and the eastern two thirds of the Ohio Valley. Central Time Zone, which comprises the Gulf Coast, Mississippi Valley, most of the Great Plains. Mountain Time Zone, which comprises the states and portions of states that include the Rocky Mountains and the western quarter of the Great Plains. Pacific Time Zone, which comprises the states on the Pacific coast, plus Nevada and the Idaho panhandle. Alaska Time Zone, which comprises most of the state of Alaska. Hawaii-Aleutian Time Zone, which includes Hawaii and most of the length of the Aleutian Islands chain. Samoa Time Zone, which comprises American Samoa. Chamorro Time Zone, which comprises Guam and the Northern Mariana Islands. Atlantic Time Zone, which comprises Puerto Rico and the US Virgin Islands; some United States Minor Outlying Islands are outside the time zones defined by 15 U.

President of the United States
The president of the United States is the head of state and head of government of the United States of America. The president directs the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. In contemporary times, the president is looked upon as one of the world's most powerful political figures as the leader of the only remaining global superpower; the role includes responsibility for the world's most expensive military, which has the second largest nuclear arsenal. The president leads the nation with the largest economy by nominal GDP; the president possesses international hard and soft power. Article II of the Constitution establishes the executive branch of the federal government, it vests the executive power of the United States in the president. The power includes the execution and enforcement of federal law, alongside the responsibility of appointing federal executive, diplomatic and judicial officers, concluding treaties with foreign powers with the advice and consent of the Senate.
The president is further empowered to grant federal pardons and reprieves, to convene and adjourn either or both houses of Congress under extraordinary circumstances. The president directs the foreign and domestic policies of the United States, takes an active role in promoting his policy priorities to members of Congress. In addition, as part of the system of checks and balances, Article I, Section 7 of the Constitution gives the president the power to sign or veto federal legislation; the power of the presidency has grown since its formation, as has the power of the federal government as a whole. Through the Electoral College, registered voters indirectly elect the president and vice president to a four-year term; this is the only federal election in the United States, not decided by popular vote. Nine vice presidents became president by virtue of a president's intra-term resignation. Article II, Section 1, Clause 5 sets three qualifications for holding the presidency: natural-born U. S. citizenship.
The Twenty-second Amendment precludes any person from being elected president to a third term. In all, 44 individuals have served 45 presidencies spanning 57 full four-year terms. Grover Cleveland served two non-consecutive terms, so he is counted twice, as both the 22nd and 24th president. Donald Trump of New York is the current president of the United States, he assumed office on January 20, 2017. In July 1776, during the American Revolutionary War, the Thirteen Colonies, acting jointly through the Second Continental Congress, declared themselves to be 13 independent sovereign states, no longer under British rule. Recognizing the necessity of coordinating their efforts against the British, the Continental Congress began the process of drafting a constitution that would bind the states together. There were long debates on a number of issues, including representation and voting, the exact powers to be given the central government. Congress finished work on the Articles of Confederation to establish a perpetual union between the states in November 1777 and sent it to the states for ratification.
Under the Articles, which took effect on March 1, 1781, the Congress of the Confederation was a central political authority without any legislative power. It could make its own resolutions and regulations, but not any laws, could not impose any taxes or enforce local commercial regulations upon its citizens; this institutional design reflected how Americans believed the deposed British system of Crown and Parliament ought to have functioned with respect to the royal dominion: a superintending body for matters that concerned the entire empire. The states were out from under any monarchy and assigned some royal prerogatives to Congress; the members of Congress elected a President of the United States in Congress Assembled to preside over its deliberation as a neutral discussion moderator. Unrelated to and quite dissimilar from the office of President of the United States, it was a ceremonial position without much influence. In 1783, the Treaty of Paris secured independence for each of the former colonies.
With peace at hand, the states each turned toward their own internal affairs. By 1786, Americans found their continental borders besieged and weak and their respective economies in crises as neighboring states agitated trade rivalries with one another, they witnessed their hard currency pouring into foreign markets to pay for imports, their Mediterranean commerce preyed upon by North African pirates, their foreign-financed Revolutionary War debts unpaid and accruing interest. Civil and political unrest loomed. Following the successful resolution of commercial and fishing disputes between Virginia and Maryland at the Mount Vernon Conference in 1785, Virginia called for a trade conference between all the states, set for September 1786 in Annapolis, with an aim toward resolving further-reaching interstate commercial antagonisms; when the convention failed for lack of attendance due to suspicions among most of the other states, Alexander Hamilton led the Annapolis delegates in a call for a convention to offer revisions to the Articles, to be held the next spring in Philadelphia.
Prospects for the next convention appeared bleak until James Madison and Edmund Randolph succeeded in securing George Washington's attendance to Philadelphia as a delegate for Virginia. When the Constitutional Convention convened in May 1787, the 12 state delegations in attendance (Rh
Tyler is the county seat of Smith County, located in east-central Texas, United States. The city of Tyler has long been Smith County's major economic, financial and cultural hub; the city is named for the tenth President of the United States. Tyler had a population of 96,900 in 2010, according to the United States Census Bureau, Tyler's 2017 estimated population was 104,991, it is 100 miles east-southeast of Dallas. Tyler is the principal city of the Tyler Metropolitan Statistical Area, which had a population of 209,714 in 2010, is the regional center of the Tyler-Jacksonville combined statistical area, which had a population of 260,559 in 2010. Tyler is known as the "Rose Capital of America", a nickname it earned from a long history of rose production and processing, it is home to the largest rose garden in the United States, a 14-acre public garden complex that has over 38,000 rose bushes of at least 500 different varieties. The Tyler Rose Garden is home to the annual Texas Rose Festival, attracting tourists by the thousands each year in mid-October.
Tyler is home to the Caldwell Zoo and Broadway Square Mall. As a regional educational and technology center, Tyler is the host for more than 20,000 higher-education students, a college of engineering, a university health science center, two regional hospital systems. In 1985, the international Adopt-a-Highway movement originated in Tyler. After appeals by local Texas Department of Transportation officials, the local Civitan chapter adopted a 2-mi stretch of U. S. Highway 69 to maintain. Drivers and other motorists traveling on this segment of US-69 will notice brown road signs that read, "First Adopt-A-Highway in the World." Tyler is located at 32°20′03″N 95°18′00″W at 544 feet above sea level. Tyler is surrounded by many smaller cities, including Whitehouse, New Chapel Hill, Edom, Kilgore and Chandler. According to the United States Census Bureau, the city has a total area of 54.4 square miles, of which 54.2 mi2 are land and 0.1 mi2 is covered by water. Tyler experiences weather typical of East Texas, unpredictable in the spring.
All of East Texas has the humid subtropical climate typical of the American South. The record high for Tyler is 115 °F, which occurred in 2011; the record low for Tyler is −3 °F, which occurred on January 18, 1930. As of the 2010 census, 96,900 people resided in the city of Texas; the population density was 1,782.0 people per square mile. The 41,742 housing units averaged a density of 716.7 per mi2. The racial makeup of the city was: 60.5% White, 24.8% Black, 0.5% Native American, 1.9% Asian, 0.03% Pacific Islander, 10.3% from other races, 2.0% from two or more races. About 21.2 % of the population were Latino of any race. The median income for the city was $42,752 and the poverty rate was 19.5%. Legal recognition of Tyler was initiated by an act of the state legislature on April 11, 1846. Texas authorized a county seat; the first plat designated a 28-block town site centered by a main square, located within a 100-acre tract acquired by Smith County on February 6, 1847. The new town was named for President John Tyler, who advocated for annexation of Texas by the United States.
A log building on the north side of the square functioned as courthouse and public meeting hall until it was displaced by a brick courthouse in 1852. On January 29, 1850, Tyler was incorporated. Early religious and social institutions included the First Baptist church and a Methodist church, a Masonic Lodge and an Odd Fellows Lodge, Tyler’s first newspaper. Though Tyler’s early economy was based on agriculture, it was well-diversified during this period. Logging was a second major industry, while complementary manufacturing included metal working, milling wood, leather tanning; as the seat of Smith County, the town benefited from government activity. The local agricultural economy relied on slave labor before the Civil War. By 1860, Tyler held over 1000 enslaved persons, which represented 35 percent of the town’s population. So there was strong support for secession and the Confederacy within Tyler, as a high percentage of its residents voted for secession and many of its men joined the Confederate Army.
The town was secure enough for the Confederacy to establish the largest ordnance plant in Texas. In 1870, the first bank in Tyler was established by Williams. Though both the Texas and Pacific Railroad and the International Railroad eschewed routes through Tyler, the town gained an important rail connection when the Houston and Great Northern built a branch line in 1874. Toward the end of the nineteenth century, fruit orchards emerged as an important new business in the regional economy. Eighty percent of the county agricultural revenue derived from cotton as it persisted as the dominant crop in the first decades of the twentieth century. Peaches were the principal fruit crop as the county fruit tree inventory surpassed one million by 1900. Disease struck the peach trees and local farmers moved toward growing roses by the 1920s. Twenty years most of the US rose supply originated in the Tyler area. According to the city's most recent Comprehensive Annual Financial Report, the city's various funds had $87.7 million in revenues, $101.7 million in expenditures, $49.2 million in total assets, $12.3 million in total liabilities, $17.6 million in cash in investments.
The structure of the management and coordination of city services is: The Northeast Texas Public Health District is a political subdivision under the State
Texas Recreational Road 255
Recreational Road 255 is a Recreational Road located in Tyler and Newton counties, in the southeastern region of the U. S. state of Texas. The highway is 56.6 miles long, travels through rural areas in the northern portion of the three counties. RE 255 begins at an intersection with U. S. Route 69, near the city of Colmesneil; the route travels through rural farmland in northern Tyler County, crosses the Neches River into Jasper County. The roadway intersects State Highway 63 and US 96, helps form part of the Sam Rayburn Dam; the route continues into Newton County, intersecting TX 87, before terminating at an intersection with Farm to Market Road 692, near the Louisiana border. RE 255 helps provide access to Angelina National Forest, the Sam Rayburn Reservoir, the Toledo Bend Reservoir, which give the highway its Recreational Road designation. Recreational Road 255 began as Farm to Market Road 255, with the first section of the route being designated in 1945. Throughout the 1950s and the 1960s, FM 255 was extended several times, with the final extension being made in early 1970.
The first stretch of RE 255 was designated in 1970 by Minute Order 063535, creating the first Recreational Road. The highway was extended three more times in the 1970s replacing FM 255. FM 255 had a short spur, designated in 1970, was transferred over to RE 255 in 1974 when the main route was replaced. RE 255 Spur was cancelled in 1979. Recreational Road 255 begins at its western terminus at an intersection with U. S. Route 69 as a two-lane, paved road; the highway proceeds eastward through rural areas, passing several small farms. The roadway continues, turning northeast; the road proceeds northeast before bending east again and continuing. It turns northeasterly. RE 255 continues, passing several homes and the small Gregory Cemetery as well as intersecting several county roads and bending east; the route continues easterly, passing through a large forest and intersecting CR 3725 before crossing the Neches River and exiting Tyler County. After crossing the Neches River, RE 255 enters proceeds easterly.
After a short distance, it crosses over a small relief creek for the Neches River and continues through forested rural areas before turning southeast. The route proceeds over a small creek before bending northeastward; the roadway passes the small community of Beans. While traveling through Beans, the road passes several small houses, it intersects several county roads, including the former RE 255 Spur, now CR 32. The highway enters Angelina National Forest. Recreational Road 255 continues northeasterly, passing through farmland before reaching its junction with SH 63. RE 255 continues northward, entering the community of Ebenezer and intersecting a few local roads in the community; the roadway passes the McGee Cemetery. RE 255 proceeds to the Angelina River at the Sam Rayburn Dam; the road bends northeastward, passing through the small Overlook Park and continuing northeast along the dam. It continues along the dam; the dam ends after 1.5 miles and the highway exits Angelina National Forest and enters Twin Dikes Park.
The roadway continues, taking a large bend southeast and intersecting several local roads that lead to the reservoir. The highway proceeds southeasterly, passing several small homes and businesses that make up a portion of the community of Sam Rayburn. RE 255 proceeds northeast for a short distance before shifting eastward through Rayburn Country and intersecting FM 1007. Turning southeast, the route passes the southern edge of the Rayburn Country golf resort before exiting the community of Sam Rayburn and reentering rural areas. RE 255 shifts southeast and proceeds to an intersection with U. S. Route 96, a divided highway; the route bends northeasterly. RE 255 enters Newton County traveling eastward; the highway proceeds eastward before entering dense forest. Continuing eastward, the road reaches an intersection with SH 87; the route continues east. The highway intersects a couple of county routes and turns east before crossing over a small cove on the Toledo Bend Reservoir. RE 255 the enters the community of South Toledo Bend.
It travels parallel to the reservoir. RE 255 passes the Shady Oaks Marina and the Sam Forse Collins Recreational Area before reaching its eastern terminus at an at-grade intersection with FM 692; the Texas Department of Transportation publishes yearly reports of the highway's annual average daily traffic, with counts taken near intersections. In 2010, RE 255's highest traveled point was at the intersection with FM 1007, with a daily county of 2,800 vehicles; the lowest traveled point along the highway is just east of the intersection with SH 87, with a daily county of 550 vehicles. The most traveled point in Tyler County is at the intersection with US 69, with a daily count of 1,100 vehicles; the intersection with FM 1007 has the highest AADT counts in Jasper County, while the most densely traveled point in Newton County is near the intersection with FM 692, at a count of 880 vehicles. These counts are somewhat higher than those of 2008, when the highest taken count, at the FM 1007 intersection, was at just 2,200 vehicles.
The least traveled point had a count of 510 vehicles. At 56.596 miles long, RE 255 is the longe
1940 United States Census
The Sixteenth United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 132,164,569, an increase of 7.3 percent over the 1930 population of 123,202,624 people. The census date of record was April 1, 1940. A number of new questions were asked including where people were 5 years before, highest educational grade achieved, information about wages; this census introduced sampling techniques. Other innovations included a field test of the census in 1939; this was the first census in which every state had a population greater than 100,000. The 1940 census collected the following information: In addition, a sample of individuals were asked additional questions covering age at first marriage and other topics. Full documentation on the 1940 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series. Following completion of the census, the original enumeration sheets were microfilmed; as required by Title 13 of the U.
S. Code, access to identifiable information from census records was restricted for 72 years. Non-personally identifiable information Microdata from the 1940 census is available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. On April 2, 2012—72 years after the census was taken—microfilmed images of the 1940 census enumeration sheets were released to the public by the National Archives and Records Administration; the records are indexed only by enumeration district upon initial release.

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.
