The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, and a federal district. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. The largest of these territories are Puerto Rico and the American Virgin Islands which are an official part of the United States. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the U.S. mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
The geography of Texas is diverse and far reaching in scope. Occupying about 7% of the total water and land area of the U.S., it is the second largest state after Alaska, and is the southernmost part of the Great Plains, which end in the south against the folded Sierra Madre Oriental of Mexico. Texas is in the south-central part of the United States of America, and is considered to form part of the U.S. South and also part of the U.S. Southwest.
By residents, the state is generally divided into North Texas, East Texas, Central Texas, South Texas, West Texas (and sometimes the Panhandle), but according to the Texas Almanac, Texas has four major physical regions: Gulf Coastal Plains, Interior Lowlands, Great Plains, and Basin and Range Province. This has been cited as the difference between human geography and physical geography, although the fact that Texas was granted the prerogative to divide into as many as five U.S. states may be a historical motive for Texans defining their state as containing exactly five regions.
The Dallas–Fort Worth–Arlington, TX Metropolitan Statistical Area, the official title designated by the United States Office of Management and Budget, encompasses 12 counties within the U.S. state of Texas. The area is divided into two distinct metropolitan divisions: Dallas–Plano–Irving and Fort Worth–Arlington. Residents of the area informally refer to it as the Dallas/Fort Worth Metroplex, DFW, or The Metroplex. It is the economic and cultural hub of the region commonly called North Texas or North Central Texas and is the largest land-locked metropolitan area in the United States.
The 2011 official estimate U.S. Census has the Dallas–Fort Worth Metroplex at 6,526,548, making it the largest metropolitan area in the South. During the 12-month period from July 2008 to July 2009, the Dallas–Fort Worth–Arlington metropolitan area gained 146,530 new residents, more than any other metropolitan area in the United States. The area's population has grown by about one million since the last census was administered in 2000. The Dallas–Fort Worth–Arlington MSA is, by population, the largest metropolitan area in Texas, the largest in the South, the fourth-largest in the United States, and the tenth-largest in the Americas. The metroplex encompasses 9,286 square miles (24,100 km2) of total area: 8,991 sq mi (23,290 km2) is land, while 295 sq mi (760 km2) is water, making it larger in area than the U.S. states of Rhode Island and Connecticut combined. It is also the sixth largest gross metropolitan product (GMP) in the United States, and approximately tenth largest by GMP in the world.
The United States is a country in the Northern Hemisphere, Western Hemisphere, and the Eastern Hemisphere. It consists of forty-eight contiguous states in North America, Alaska, a peninsula which forms the northwestern most part of North America, and Hawaii, an archipelago in the Pacific Ocean. There are several United States territories in the Pacific and Caribbean. The term "United States", when used in the geographical sense, means the continental United States, Alaska, Hawaii, Puerto Rico, Guam, and the Virgin Islands of the United States. The country shares land borders with Canada and Mexico and maritime (water) borders with Russia, Cuba, and the Bahamas in addition to Canada and Mexico.
Dallas County is a county located in the U.S. state of Texas within the Dallas–Fort Worth–Arlington metropolitan area (colloquially referred to as the Dallas/Fort Worth Metroplex). As of the 2010 census, the county had an official population of 2,368,139 and is now the ninth most populous county in the United States. The county was founded in 1846 and was possibly named for George Mifflin Dallas, the 11th Vice President of the United States under U.S. President James K. Polk.
Its county seat is Dallas, which is also the largest city in the county, the third-largest city in Texas, and the eighth-largest city in the United States.

This article is about the culture of Dallas, Texas (USA).
A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
