About 96 percent of U.S. adults have had sex.
Sixteen percent of adults first had sex before age 15, while 15 percent abstained from sex until at least age 21.
The proportion of adults who first had sex before age 15 was highest for non-Hispanic black people (28 percent) compared with 14 percent for Mexican-Americans and non-Hispanic white people.
Six percent of black people abstained from sex until age 21 or older, fewer than Mexican-Americans (17 percent) or non-Hispanic white people (15 percent).
Black men and women were more likely to report having 15 or more partners in a lifetime (46 percent and 13 percent, respectively) than other racial or ethnic groups.
Twenty-five percent of women and 17 percent of men reported having no more than one partner of the other sex in their lifetime.
Twenty-six percent of men and 17 percent of women have tried cocaine or other street drugs (not including marijuana).
Non-Hispanic white people had a higher percentage of ever using cocaine or street drugs (23.5 percent) than black (18 percent) or Mexican-American (16 percent) people.
Adults who were married or had more than a high school education were less likely to use street drugs than others.
The survey, formally titled the National Health and Nutrition Examination Survey, did not include the homeless, prison inmates or other institutionalized adults.
