American Community Survey in the context of "Race and ethnicity in the United States"

The most commonly used language in the United States is English (specifically American English), which is the national language. While the U.S. Congress has never passed a law to make English the country's official language, a March 2025 executive order declared it to be. In addition, 32 U.S. states out of 50 and all five U.S. territories have laws that recognize English as an official language, with three states and most territories having adopted English plus one or more other official languages. Overall, 430 languages are spoken or signed by the population, of which 177 are indigenous to the U.S. or its territories, and accommodations for non-English-language speakers are sometimes made under various federal, state, and local laws.

The majority of the U.S. population (77%) speaks only English at home as of 2024, according to the American Community Survey (ACS) of the U.S. Census Bureau. The second most common language by far is Spanish, spoken by 13.9% of the population, followed by Chinese, spoken by around 1% of the population. Other languages spoken by over a million residents are Tagalog, Vietnamese, Arabic, French, Korean, and Russian. Only 8.4% of U.S. residents report that they speak English less than "very well".

The United States census (plural censuses or census) is a decennial census that is legally mandated by the Constitution of the United States. The first census after the American Revolution was taken in 1790 under Secretary of State Thomas Jefferson. There have been 24 federal censuses since that time. The census includes territories of the United States. The United States Census Bureau is responsible for conducting the census.

The most recent national census took place in 2020; the next census is scheduled for 2030. Since 2013, the Census Bureau began discussions on using technology to aid data collection starting with the 2020 census. In 2020, every household received an invitation to complete the census over the Internet, by phone or by paper questionnaire. For years between the decennial censuses, the Census Bureau issues estimates made using surveys and statistical models, in particular, the Population Estimates Program and American Community Survey.

Per capita income (PCI) or average income measures the average income earned per person in a given area (city, region, country, etc.) in a specified year.

In many countries, per capita income is determined using regular population surveys, such as the American Community Survey. This allows the calculation of per capita income for both the country as a whole and specific regions or demographic groups. However, comparing per capita income across different countries is often difficult, since methodologies, definitions and data quality can vary greatly. Since the 1990s, the OECD has conducted regular surveys among its 38 member countries using a standardized methodology and set of questions.

Northern Virginia, locally referred to as NOVA or NoVA, comprises several counties and independent cities in the Commonwealth of Virginia in the United States. The region radiates westward and southward from Washington, D.C., the nation's capital, and has a population of 3,257,133 people as of 2023 U.S. Census Bureau estimates, representing over a third of the state's total population. It is the most populous region in both Virginia and the regional Washington metropolitan area.

Communities in the region form the Virginia portion of the Washington metropolitan area and the larger Washington–Baltimore metropolitan area. Northern Virginia has a significantly larger job base than either Washington, D.C. or the Maryland portion of its suburbs, and is the highest-income region of Virginia, with several of the highest-income counties in the nation, including three of the ten highest counties for median household income, according to the 2019 American Community Survey.

White Americans (sometimes also called Caucasian Americans) are Americans who identify as white people. In a more official sense, the United States Census Bureau, which collects demographic data on Americans, defines "white" as "[a] person having origins in any of the original peoples of Europe, the Middle East, or North Africa". Individuals within this group have light skin tones and hair colors that include brown, blonde, black or red. White Americans have historically constituted the majority population in the United States, though their share has been gradually declining in recent decades. As of the latest American Community Survey conducted by the U.S. Census Bureau in 2024, an estimated 59.8% of the U.S. population—approximately 203.3 million people—identify as White alone, while Non-Hispanic Whites account for 56.3% of the population, or roughly 191.4 million people. Overall, 72.1% of Americans identify as White either alone or in combination with one or more other racial groups. European Americans are by far the largest panethnic group of white Americans and have constituted the majority population of the United States since the nation's founding. Middle Eastern Americans constitute a much smaller demographic of white Americans, making up around 1.1% of the US population in 2020.

According to the 2020 census, 61.6% of Americans, or 204,277,273 people, identified as White alone. This represented a national decrease from a 72.4% white alone share of the US population in the 2010 census. The share of Americans identifying as White alone or in combination (including multiracial white people) was 71.0% in 2020, a smaller decline from 74.8% of the population in 2010. As opposed to the declines seen in the white alone population, the number of people identifying as part white (in combination with other races) saw a large increase, growing from 2.4% of the population in 2010, to 9.4% in 2020.

The 2000 United States census, conducted by the Census Bureau, determined the resident population of the United States on April 1, 2000, to be 281,421,906, an increase of 13.2 percent over the 248,709,873 people enumerated during the 1990 census. This was the twenty-second federal census and was at the time the largest civilly administered peacetime effort in the United States.

Approximately 16 percent of households received a "long form" of the 2000 census, which contained over 100 questions. It would be the last census to include the "long form", since subsequent censuses, starting with the 2010 census, would be "short form" only, with the more detailed questions being replaced by the new American Community Survey. Full documentation on the 2000 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series.

Mantoloking (/ˌmæntəˈloʊkɪŋ/, MAN-ta-LO-king) is a coastal borough in Ocean County, in the U.S. state of New Jersey. As of the 2020 United States census, the borough's population was 331, an increase of 35 (+11.8%) from the 2010 census count of 296, which in turn reflected a decline of 127 (−30.0%) from the 423 counted in the 2000 census. The borough has an estimated summer population of approximately 5,000.

As of the 2000 census, Mantoloking was the highest-income community in the state of New Jersey with a per capita money income of $114,017 as of 1999, an increase of 29.8% from the $87,830 recorded in 1989. Based on data from the 2006–2010 American Community Survey, the borough had a per-capita income of $97,938, ranked 4th in the state. In the Forbes magazine 2012 rankings of "America's Most Expensive ZIP Codes", the borough was ranked 139th, with a median price of $1,403,349.

Scotch-Irish Americans are American descendants of primarily Ulster Scots people, who emigrated from Ulster (Ireland's northernmost province) to the United States between the 18th and 19th centuries, with their ancestors having originally migrated to Ulster, mainly from the Scottish Lowlands and Northern England in the 17th century.

In the 2017 American Community Survey, 5.39 million (1.7% of the population) reported Scottish ancestry, an additional 3 million (0.9% of the population) identified more specifically with Scotch-Irish ancestry, and many people who claim "American ancestry" may actually be of Scotch-Irish ancestry.
