Income Data for Policy Analysis: A Comparative Assessment of Eight Surveys. APPENDIX B: QUESTIONNAIRES, DATA DICTIONARIES AND DOCUMENTATION

QUESTIONNAIRES, DATA DICTIONARIES AND DOCUMENTATION

 

Questionnaires, Data Dictionaries and Documentation

 

This Appendix provides internet addresses for detailed documentation and other information for each survey used in the study—the 2001 SIPP panel, 2002 files for ACS and MEPS, 2003 files for CPS (ASEC), NHIS, MCBS and PSID, and 2004 files for HRS.

The Appendix first lists main web sites, then internet addresses for questionnaires, data dictionaries, file- and year-specific documentation, information on survey design including sampling and weights, and last, other documentation. However, some information on MCBS, as well as any information on internal NHIS files, is available only after a research plan has been approved. NHIS information listed below pertains to the public use files that have income brackets, not income amounts. <
