Abstract: The study of occupations has a long history in the social sciences. The United States Census Bureau creates occupation codes to systematically identify similar jobs and classify them into occupations; since 1980 Census occupation codes are based on the Standard Occupation Classification System. Periodic updates to occupation codes are necessary for documenting emerging and disappearing occupations and appropriately reflecting the labor market. While these updates are important for capturing the changing jobs that are performed in the United States, occupation code changes make it more complicated for researchers to make appropriate comparisons over time. This paper presents the methodology used at IPUMS to harmonize 2010 and 2002 Census occupation codes. Our work builds upon the foundation of existing harmonized occupation data available through IPUMS (variables OCC1950 and OCC1990). Combining our contribution with existing IPUMS infrastructure creates a consistent measure of occupation for all seven coding schemes over the 1950-2017 period.
