The release of total population estimates at the end of the calendar year also includes demographic components of change. In the spring, the Program releases population by age and sex, presenting tables for different age groupings as well as single year of age. A third release in the summer presents estimates by age, sex, race, and Hispanic origin.
All estimates are for the resident population unless noted otherwise.
The reference date for state estimates is July 1. In addition to the Census data released through FactFinder, there are other population tables and reports available. The reports include the Census 2000 Brief series, as well as tables providing rankings of population changes between 1990 and 2000 for states, counties, metropolitan areas, and large cities. Some of these files are also available in compressed format for faster downloading.
