Census Data
1. Most rates for birth, death and morbidity are calculated with census population estimates as the denominator; misreporting occurred in 1990 Census with undercounting of Blacks, American Indians and Alaskan Natives, Asian and Pacific Islanders, and Hispanics at higher rates than Whites
- Any rate that uses an undercounted denominator is overestimated in proportion to the undercount in the denominator; unfortunately, estimates of undercount are generally only available at the national level
