POPULATION PROJECTIONS OF THE UNITED STATES BY AGE, SEX, RACE, HISPANIC ORIGIN, AND NATIVITY: 1999 TO 2100 Source: Population Projections Program, Population Division, U.S. Census Bureau, Washington, D.C. 20233 (301) 763-2428 Internet Release Date: January 13, 2000 Revised Date: February 14, 2000 I. PRINTING A SUMMARY TABLE Before printing a summary table, set the following printing options: Paper Size: Letter (8.5 inches by 11 inches) Orientation: Portrait Left and Right Margins: 1 inch Top and Bottom Margins: 1 inch Font: Courier New, 10 point size These options will ensure that the printed pages match in both width and length with the summary table pages. Most tables are available in ASCII (.txt) format or as a portable document file (.pdf). II. UNIVERSE DESCRIPTION The projections are produced for the resident population of the United States which includes people who reside in the 50 states and the District of Columbia. They exclude residents of the Commonwealth of Puerto Rico, and residents of the outlying areas under United States sovereignty or jurisdiction (principally American Samoa, Guam, Virgin Islands of the United States, and the Commonwealth of the Northern Mariana Islands). The definition of residence conforms to the criteria used in the 1990 census, which defines a resident of a specified area as a person "usually resident" in that area. The projections exclude the United States Armed Forces Overseas, as well as civilian United States citizens whose usual place of residence is outside the United States. The foreign-born population is designated by the absence of United States citizenship at birth and includes naturalized citizens and non-citizens residing in the United States. Consequently, a person is considered "native" if he or she is born in the United States or is born abroad to at least one parent with U.S. citizenship. III. RACE AND ETHNIC DEFINITIONS AND CONCEPTS The racial classification used by the Census Bureau generally adheres to the guidelines in Federal Statistical Directive No. 15, issued by the Office of Management and Budget, which provides standards on race and Hispanic origin categories for statistical reporting to be used by all Federal agencies. The race and Hispanic origin categories are defined as follows: American Indian, Eskimo, and Aleut: A person having origins in any of the original peoples of North America, who maintains cultural identification through tribal affiliation or community recognition. Asian and Pacific Islander: A person having origins in any of the original peoples of the Far East, Southeast Asian, the Indian subcontinent, or the Pacific Islands. This area includes, for example, China, India, Japan, Korea, the Philippine Islands, and Samoa. Black: A person having origins in any of the black racial groups of Africa. Hispanic: A person of Mexican, Puerto Rican, Cuban, Central or South American or other Spanish culture or origin, regardless of race. White: A person having origins in any of the original peoples of Europe, North Africa, or the Middle East. IV. ALTERNATIVE PROJECTION SERIES Four alternative projections series are available. The assumptions used for each series are as follows: ASSUMPTIONS Life Net Fertility Expectancy Immigration ------------------------------------------ Lowest Series Low Low Low Middle Series Middle Middle Middle Highest Series High High High Zero International Migration Series Middle Middle Zero The zero international migration series assumes that net international migration is zero throughout the projection horizon. Therefore, the net migration rate to the U.S. is zero. However, a small net balance of U.S. citizens is assumed to migrate to the U.S. from abroad, and is shown as the net migration to the U.S. in the zero international migration components table. V. ASSUMPTIONS AND METHODOLOGY The population projections are created using the cohort-component model. For a detailed description of the model, the assumptions, and the data used to create these projections, see the working paper, "Methodology and Assumptions for the Population Projections of the United States: 1999 to 2100, Working Paper #38."
