Summary health statistics for the U.S. population: National Health Interview Survey, 2005.
OBJECTIVE
This report presents both age-adjusted and unadjusted health statistics from the 2005 National Health Interview Survey (NHIS) for the civilian noninstitutionalized population of the United States, classified by sex, age, race, Hispanic or Latino origin and race, education, family income, poverty status, health insurance coverage (where appropriate), place of residence, and region of residence. The topics covered are respondent-assessed health status, limitations in activities, special education or early intervention services, injury and poisoning episodes, health care access and utilization, and health insurance coverage.


METHODS
NHIS is a household, multistage probability sample survey conducted annually by interviewers of the U.S. Census Bureau for the Centers for Disease Control and Prevention's National Center for Health Statistics. In 2005, household interviews were completed for 98,649 persons living in 38,509 households, reflecting a household response rate of 86.5%.


CONCLUSIONS
Nearly 7 in 10 persons were in excellent or very good health in 2005. About 34 million persons (12%) were limited in their usual activities due to one or more chronic health conditions. About 4 million persons (2%) required the help of another person with activities of daily living, and about 8 million persons (4%) required the help of another person with instrumental activities of daily living. About 6% of children received special education or early intervention services. Among persons under age 65 years, about 42 million (17%) did not have any health insurance coverage. The most common reason for lacking health insurance was cost, followed by a change in employment.
