Locating & Using Census Information

Census 2000 Summary File 3 (SF 3)

• Summary File 3 presents detailed population and housing data (such as place of birth, education, employment status, income, value of housing unit, year structure built) collected from a 1-in-6 sample and weighted to represent the total population.

• Allows users to access data from the 2000 and 1990 Decennial Census, the 1997 Economic Census, and the American Community Survey. American FactFinder is a service of the U.S. Census Bureau.

• As part of the Census 2000 geographic product series, the Census Bureau has produced Census Tract Relationship Files. (In previous censuses, this product was called a comparability file.) These files show how 1990 census tracts relate to Census 2000 census tracts. The files consist of one record per each 1990 census tract/2000 census tract spatial set. A spatial census tract set is defined as the area that is uniquely shared between a 1990 census tract and a 2000 census tract.

• A brief glossary of geographic terms you might run into as you look for census materials.

• Information about where and what census tracts are available in the UMBC Library.

• Population, demographics, and economic data for all states and counties, from the United States decennial census, 1790 - 1970.

• Use this to identify places to view with the Tiger Map Server or obtain census data from the 1990 Census Lookup server. You can search for places, counties or MCDs by entering the name and state abbreviation (optional), or 5-digit zip code.
