The gap in life expectancy between white and black populations in the United States has diminished since 1970. But by 2010, white populations still could expect to live about 4 years longer than black populations, according to the National Center for Health Statistics (NCHS).
In a recent data brief, the NCHS reported that overall US life expectancy has increased 11% in the past 40 years, to about 79 years in 2010 compared with approximately 71 years in 1970. For black individuals, the increase was 17%, to 75 years from 64 years. For white individuals, the increase was 10%, to about 79 years from approximately 72 years.
