Summary File – 1
In cities and towns across the country, community leaders use census numbers to decide where to locate police and fire stations and other public services. The census helps local government and community organizations to locate facilities, such as day-care centers, senior citizen community centers, health-care clinics and even playgrounds
Notes:
The first release of Census 2000 information, the Redistricting Summary File (Public Law 94-171), provided a count of the population by race, Hispanic origin, and voting age.
The next release of Census 2000 information, Summary File 1, provides additional demographic and housing detail.
