This publication provides detailed population estimates by gender and age for state and county. Age data is broken into one-year cohorts for ages 0 to 19, 5-year cohorts for ages 0 to 84, and a single cohort for age 85 and older. In addition, population estimates by race (White, Black or African-American and Hispanic ethnicity) were developed for the state and selected counties. Population figures from the 2000 decennial census and 2003 estimates are provided for comparative purposes, in addition to graphs and maps illustrating population change.
