This project provides a coding of EGP social classes that can be implemented for data sources, such as the General Social Survey, that utilize the 2010 US Census occupational classification. The associated report explains the rationale for the coding as well as the specific coding decisions. It demonstrates how to implement the coding for the General Social Survey, and it presents a comparison of EGP social classes in both the GSS and the American Community Survey. Additional detail ----------------- Beginning with the 2012 General Social Survey, job titles and job activity descriptions have been coded using only the 539-category 2010 US Census occupational classification. As of July 2016, most job titles and descriptions from prior administrations of the GSS were also recoded to the 2010 census occupation codes. A reasonable expectation is that the 2010 census occupation codes will continue to be used for the GSS at least until 2022. For analysts who wish to have a measure of social class, any principled coding of the 2010 occupation codes can be used to group related occupations into larger agglomerations, perhaps using additional information on individuals drawn from work histories and current labor market status. In the linked GSS Methodological Report No. 125, "A Coding of Social Class for the General Social Survey," I share the results of one such coding effort that I undertook in preparation for analysis of the 2016 GSS, during a time when conjectures about class-specific political attitudes and voting trends had received renewed attention in the United States. The specific social class coding explained in the report is available in the linked .csv file, occ10-to-egp-class-crosswalk.csv. It is also shown in tabular form in the report. Because this coding represents only one coding for how social class categories can be formed, it is not included as an official variable in any of the GSS data files. However, it can be matched to all GSS respondents who have valid codes for the variable occ10, as demonstrated in the report with sample Stata code. The social class coding can also be used with minor modifications in any other data source that has occupation codes traceable to the 2010 Standard Occupational Classification of the United States. This social class coding was first used in: - Morgan, Stephen L. and Jiwon Lee. 2017. “[Social Class and Party Identification During the Clinton, Bush, and Obama Presidencies][1].” Sociological Science 4:394-423. It has been used in a number of additional publications linked in projects on my OSF profile. An extension to the 2000 Census Occupation Codes is detailed in Table S5 of the" - online [Supplementary Appendix][2] to the article Morgan, Stephen L. and Jiwon Lee. 2017.
