The first issue of the Population Profile of the United States was published in 1974. Originally updates were published every year, but the schedule was soon modified to alternate years. The last printed version of the Population Profile used 1999 data and was issued in 2001. In 2002, the first Internet-only version of the Profile was posted on the Web. The individual chapters of the new Dynamic Version of the Population Profile will be updated on an ongoing basis.
The primary sources for this report are the U.S. Census Bureau’s Population Estimates Program, the Current Population Survey (CPS), the American Community Survey (ACS), the Survey of Income and Program Participation (SIPP), and the American Housing Survey (AHS). Data for the United States cover the 50 states and the District of Columbia.
Estimates from survey data are based on responses from a sample of the population. The different population universes for these surveys are noted in each chapter. As with all surveys, estimates may vary from the actual values because of sampling variation or other factors. All comparisons of survey estimates made in this report have undergone statistical testing and are significant at the 90-percent confidence level unless otherwise noted. For more information on the accuracy of the data, see Appendix A.
