Census-designated Place
A census-designated place (CDP) is a concentration of population defined by the United States Census Bureau for statistical purposes only. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, such as self-governing cities, towns, and villages, for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, edge cities, colonias located along the Mexico–United States border, and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unin ...

The term "African American" generally denotes descendants of enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West/Central African with some European descent; some also have Native American and other ancestry.

White (U
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

Population Density
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. In simple terms, population density refers to the number of people living in an area per square kilometre, or other unit of land area. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usuall ...

Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

Hispanic And Latino Americans
Hispanic and Latino Americans ( es, Estadounidenses hispanos y latinos; pt, Estadunidenses hispânicos e latinos) are Americans of Spanish and/or Latin American ancestry. More broadly, these demographics include all Americans who identify as Hispanic or Latino regardless of ancestry.Mark Hugo Lopez, Jens Manuel Krogstad and Jeffrey S. PasselWho Is Hispanic? Pew Research Center (November 11, 2019). As of 2020, the Census Bureau estimated that there were almost 65.3 million Hispanics and Latinos living in the United States and its territories (which include Puerto Rico). "Origin" can be viewed as the ancestry, nationality group, lineage or country of birth of the person or the person's parents or ancestors before their arrival in the United States of America. People who identify as Hispanic or Latino may be of any race. As one of the only two specifically designated categories of ethnicity in the United States (the other being "Not Hispanic or Latino"), Hispanics and Latinos f ...

Multiracial Americans
Multiracial Americans are Americans who have mixed ancestry of two or more races. The term may also include Americans of mixed race ancestry who self-identify with just one group culturally and socially (cf. the one-drop rule). In the 2010 United States census, approximately 9 million individuals or 3.2% of the population, self-identified as multiracial. There is evidence that an accounting by genetic ancestry would produce a higher number. Historical reasons are said to have created a racial caste such as the European-American suppression of Native Americans, often led people to identify or be classified by only one ethnicity, generally that of the culture in which they were raised.Gates, Henry Louis, Jr. ''Faces of America: How 12 Extraordinary Americans Reclaimed Their Pasts'' (New York University Press, 2010) Prior to the mid-20th century, many people hid their multiracial heritage because of racial discrimination against minorities. While many Americans may be considered mult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (OMB) and the United States Census Bureau, are the self-identified categories of race or races and ethnicity chosen by residents, with which they most closely identify, and indicate whether they are of Hispanic or Latino origin (the only categories for ethnicity). 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 U.S. 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 racial and national-origin groups. Race and ethnicity are considered separate and distin ...

Pacific Islander Americans
Pacific Islander Americans (also known as Oceanian Americans) are Americans who are of Pacific Islander ancestry (or are descendants of the indigenous peoples of Oceania or of Austronesian descent). For its purposes, the United States census also counts Indigenous Australians as part of this group. Pacific Islander Americans make up 0.5% of the U.S. population including those with partial Pacific Islander ancestry, enumerating about 1.4 million people. The largest ethnic subgroups of Pacific Islander Americans are Native Hawaiians, Samoans, Chamorros, Fijians, Marshalleses, Tongans, and Tahitians. American Samoa, Guam, and the Northern Mariana Islands are insular areas (U.S. territories), while Hawaii is a state. History First stage: Hawaiian migration (18th-19th centuries) Migration from Oceania to the United States began in the last decade of the 18th century, but the first migrants to arrive in the country were natives of Hawaii.
