|

|
Release date: September 2026
|
Released as an ASCII file (with SAS, SPSS, STATA, and R programming statements), a SAS transport file, a SAS V9 file, an XLSX file, and a Stata file, this public-use dataset is a two-year longitudinal file of respondents from the MEPS Panel 28 sample. The persons on this dataset represent those who were in the MEPS population (U.S. civilian noninstitutionalized) for all or part of the 2023-2024 period. The file contains a longitudinal weight variable (LONGWT) and all variables from the 2023 and 2024 Full Year Consolidated Data Files (HC-251 and HC-256, respectively). When applied to the persons who participated in both 2023 and 2024, the weight variable (LONGWT) enables users to make national estimates of person-level changes in selected variables (e.g., health insurance, health status, utilization, and expenditures). In addition, LONGWT can be used to develop cross-sectional type estimates for the two-year period or for each year individually, based on only the Panel 28 sample.
