Re-posting from EH.net: Standard Industrial Classification (SIC) codes and North American Industry Classification System (NAICS) codes

Dear Colleagues,

I am happy to share a new research tool for crosswalking between Standard Industrial Classification (SIC) codes and North American Industry Classification System (NAICS) codes. My RA, Paul DeCelles, and I developed crosswalks with weighting variables that make it possible to smoothly bridge between systems and construct consistent time series in a nonarbitrary way. Three different weighting schemes are included. The first based on employment, the second based on number of establishments, and the third based on annual payroll.
Please use freely and circulate to those who might find it helpful. Details and data available on my website, and on ICPSR: https://www.openicpsr.org/openicpsr/project/145101/version/V1/view

 

Best wishes,
