Title:	Bridging the Gaps: Dealing with Major Survey Changes in Dataset Harmonization

Abstract:	Large shifts in the survey methods employed by the Current Population Survey (CPS) and the National Health Interview Survey (NHIS) make analytical harmonization difficult. Changes present a special challenge to researchers interested in constructing an analytically consistent time series. Sampling, instrumentation, and data processing changes are the three most common challenges causing potential gaps in the analysis of trends. Changes in sampling can cause problems for variance estimation. Instrumentation changes can cause estimates to vary. These include question wording and question universe definitions. Data processing changes also can alter estimates over time. These include how missing data is handled and how out-of-range values are edited.
