Changes in Size, Race, Ethnicity & Age
Once every 10 years the U.S. Census Bureau attempts to count every person in the United States. These numbers are used to determine how many seats each state has in the U.S. House of Representatives. They are also used to redraw legislative districts in each state. In addition, these population numbers determine how much money local jurisdictions receive for many public services and projects. The Census Bureau expects that at least $182 billion will be distributed annually based on formulas using Census 2000 data. Census data on race and ethnicity are used to determine compliance with federal legislation. Census information also helps people at the local level determine where services and projects are most needed and to plan for the future. Following are Seattle statistics from Census 2000, including historical data and comparisons with other locales:
