* Estimates are based on data from the National Vital Statistics System and the National Health Interview Survey (NHIS). NHIS collects information in household interviews of a sample of the civilian noninstitutionalized U.S. population. Expected years free from activity limitations combines estimates of total life expectancy and prevalence rates of activity limitations associated with chronic conditions, which are determined from responses to several questions in the NHIS Family Core component. Questions and methods used to compute total life expectancy and expected years free of activity limitations are included in the source report.
In 2006, total life expectancy was greater for females than males and for whites than for blacks. Total life expectancy ranged from 80.6 years for white females and 76.5 years for black females to 75.7 years for white males and 69.5 years for black males. Expected years free of activity limitations was greatest for white females (69.1 years), followed by white males (65.7 years), black females (63.4 years), and black males (59.3 years).
