NBER's Mare-Winship Data -- 1964-1992

This page contains the NBER collection of Mare-Winship Data. The Mare-Winship Files are a (nearly) uniform subset of 168 variables from the Current Population Survey March Annual Demographic Supplement files. MWX.TXT is the documentation for the Mare-Winship Extracts. The original BLS/Census data and documentation is also available below. Information on weights, matching, missing data, and SAS source code for 1989-1992 are available below. Also, matching information and Stata .do files from NBER Working Paper t0247 by B. Madrian and L. J. Lefgren are available for March-to-March matches and can be modified for use in other matches. Technical Paper 63 contains more information about Design and Methodology.

Internal users can obtain the data from a UNIX shell at /homes/data/mare-winship or on an NBER PC via Network Neighborhood --> NBER --> home --> data --> mare-winship
