Estimates are based on a sample of US adults rather than the entire population. Comparisons between unadjusted or adjusted prevalence rates for different groups should take into account the 95% confidence limits
Estimates adjusted for age, sex, and race using the projected 2000 U.S. population as the standard population.
LCL is the Lower Confidence Limit.
UCL is the Upper Confidence Limit.

The National Health Interview Survey (NHIS) is an annual, in-person health survey and the principal source of information about the health of the civilian, non-institutionalized, household population of the United States. The survey is conducted by the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. The NHIS sample is designed and weighted to produce national estimates. NIOSH uses data from the NHIS to estimate the prevalence of various health conditions and health behaviors among US workers. The charts available here are based on respondents to the NHIS that were employed in the week prior to interview. Several years of data have been combined in order to create a dataset that includes adequate subsamples for various industries and occupations.
