Abstract:

The New York City (NYC) Community Health Survey (CHS) is a telephone survey of non-institutionalized adults conducted annually since 2002 by NYC's Department of Health and Mental Hygiene (DOHMH). The CHS collects information describing a wide variety of health outcomes and behaviors and is extensively used in planning and evaluation. The survey is designed to obtain estimates at the neighborhood-scale and produces estimates for 34 neighborhoods aggregated from 180 populated zip codes. However, there is growing interest in using CHS responses in conjunction with administrative data collected at the zip code scale to discern the relationship between measured health outcomes and behaviors. We use unit-level small area estimation techniques calibrated to officially-released neighborhood estimates. Despite such methods being well developed in the statistical literature, we encountered a number of practical statistical challenges not yet adequately addressed including: handling observations not associated with zip codes, collapsing small zip codes, adjusting and accounting for complex survey design, choice of population controls, and estimating trends consistent with official estimates.
