Occupation and Industry Coding in HRS/AHEAD

This document describes the codeframes that have been used to classify occupation and industry in each wave of the Health and Retirement Study. For AHEAD data collections in 1993 and 1995, occupation was coded using the SRC 2-Digit Occupation Code (adapted from the 1980 U. S. Census Occupation Code) which masked for public release.1 Unmasked codes for 1995 (but not 1993) have been released. Industry was not asked. For HRS data collections in 1992, 1994, 1996, 1998, 2000, and 2004, occupation was coded using the 3-digit 1980 U. S. Census Occupation Code and masked for public release. Industry was coded using the 3-digit 1980 U. S. Census Industry Code which was masked for public release. Except for 1994, unmasked codes have been released as restricted data. For the 2006 and 2008 interviewing periods, occupation was coded using the 3-digit 2000 U.S. Census Occupation Code; and industry was coded using the 3-digit 2002 U. S. Census Industry Code; occupation and industry were masked for public release. Unmasked versions of these codes have been released as restricted data. For HRS 2010 and beyond, occupation information was coded using the 2010 Census Occupational Classification System. Industry information reported by HRS respondents was coded using the 2007 Census Industrial Classification system. Unmasked versions of these codes have been released as restricted data.
