Households (civilian, non-institutionalized)

Address Based Sample Frame developed by the Census with oversamples of Blacks, Hispanics, and Asians


Address-based sampling using a national sample frame developed by RTI for SAMHSA

Data Collection Mode





Response Rate

54.6 (2010, 50-state median)

82.0% (2011, Household Module)

57.2% (2009, full-year file)

74.7% (2010)

Survey Period

Sample Size

Approx. 350,000 persons (only one individual interviewed per HH)

Approx. 35,000 households containing 87,500 individuals

In 2009, 13,875 households containing 34,920 individuals

State Estimates

All 50 states and DC, and many large counties and large Metropolitan areas

States are not identified on Public Use File, but direct estimates are derived by NCHS for the largest 30 states preferably using Cross year pooling


States not identified in Public Use data but SAMHSA does release small area estimates for a pre-defined set of cross-tabulations


Since 1984, annually

Since 1957 and annually since 1962

Since 1996

Since 1988, annually

Data Lag

4-6 months

Usual Source of Care, Visits, Unmet need (including dental and Rx), Patient Experience, and Costs.

Visits and Mental Health Costs


No specific measure of Medicaid coverage and income data is not precisely measured

Cannot provide state-level estimates for all states by year. Also sample size of Medicaid recipients selected as sample adult or sample child within many states will be small

Small sample size within states and the data lag time is longer

There is no established process for gaining access to states identifiers (e.g., the NHIS allows access through the Census Bureau RDC and NCHS RDC system)
