Methods to Improve the Precision of Health Statistics for Non-hispanic Asians in the National Health Interview Survey

The National Health Interview Survey (NHIS) is a major national household survey conducted by the National Center for Health Statistics (NCHS) to monitor the health of the U.S. civilian noninstitutionalized population. The NHIS is redesigned following each decennial census to achieve new survey requirements and reflect changes in the distribution of the U.S. population. The current (in use since 1995) NHIS sample design oversamples Black and Hispanic persons; however, there is no special procedure to sample Asian persons, and current statistics for this group do not meet desired precision requirements for the next NHIS design. One of the primary research objectives for the next NHIS design is to improve the precision of annual estimates for Non-Hispanic (NH) Asian persons at the national level.
