Activity limitation increases with age. For the 66.5 million noninstitutionalized persons in the U.S. under age 18, where the major activity is playing or attending school, 6.1% have activity limitations: 0.6% are unable to play or attend school, 3.9% are limited in the amount or kind of play or school they can participate in, and 1.6% are limited in a nonmajor activity. In contrast, for the 20.8 million people over age 70, where the major activity is housekeeping and self-care, a total of 39.7% are limited: 8.3% are unable to keep house or do self-care, 12.3% are limited in the amount or kind of housekeeping or self-care they can do, and 19.1% are limited in a non-major activity.
Technical Note: The definition of major activity changes after age 69, to self-care and housekeeping from work, and percentage rates for age groups above 69 years drop initially, but then increase.
