The PHC-1, "Summary Population and Housing Characteristics," report series provides data based on the 100-percent questions. The subjects are age, Hispanic or Latino origin, household relationship, race, sex, tenure (owner- or renter-occupied), and vacancy characteristics. Land area measurements and population density also are provided. This series is similar to the 1990 census CPH-1 series.

The PHC-2, "Summary Social, Economic, and Housing Characteristics," report series provides sample data on a wide range of characteristics. Population characteristics data include disability status; earnings in 1999; educational attainment; employment status; full-time, year-round workers in 1999; income in 1999; journey to work; language spoken at home and ability to speak English; nativity; place of birth; poverty status in 1999; residence in 1995; school enrollment and type of school; veteran status; and work status in 1999. Housing characteristics data include bedrooms; gross rent; house heating fuel; kitchen facilities; mortgage status; occupancy; owner costs; plumbing facilities; rental cost; rooms; telephone service available; tenure; units in structure; value of home; vehicles available; year moved into unit; and year structure built. In prior decennial census publications, the appendixes that explained these subjects, geographic terms and concepts, and other general product information were included in the volumes containing the statistical tables; for Census 2000, these appendixes are found in the PHC-2-A report, "Summary Social, Economic, and Housing Characteristics, Selected Appendixes." The PHC-2 series is similar to the 1990 census CPH-5 series.

Mapping Census 2000: The Geography of U.S. Diversity (Census Special Reports, Series CENSR/01-1) presents a synthesis of the basic patterns and changes in U.S. population distribution in the last decade. Each page features county-level detail for the 50 states, the District of Columbia, and Puerto Rico. Each page also includes a small state-level map for a simplified view of the population theme.

This report examines and discusses trends in residential segregation and includes tables, which provide descriptive statistics, changes over time, as well as magnitudes of changes for selected characteristics. In addition, there are graphical representations of residential segregation in the form of scatter plots, histograms, and maps.

The population trends in the United States reflect the country’s trends in fertility and mortality and in internal and international migration. These components underlie the changes in the size of our population, its geographic distribution, its age and sex composition, and its racial and ethnic composition. They also influence changes in the country’s housing and household composition. The trends examined in this report represent the subject areas covered by the population census of the United States on a 100-percent basis in Census 2000. That is, the data reflect information collected in census questionnaires for the entire population. Subject items collected on a sample basis (about one-sixth of all U.S. households since 1980) are not included.
