NBER's Mare-Winship Data
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.
File size: .Z files are 10-11 Mb; .zip files are 7-8 Mb. Uncompressed files are about 60 Mb.
Both ".Z" and ".zip" files can be uncompressed with winzip. In addition, ".Z" files can be uncompressed using the UNIX uncompress command and ".zip" files can be unzipped with uncompression software. To check ability to uncompress these files, download the small files compress.Z or compress.zip. These files give an example of how to read .Z and .zip ASCII files into SAS for UNIX without decompressing the files. To download files in Internet Explorer, right click on them and select "Save Target As...". If the pdf documents appear to be all blank pages, get the latest Acrobat Reader at www.abobe.com. 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
