The code that creates the EPI extracts and documentation is available on Github.


The current extracts draw extensively from excellent work by

  • CEPR: extensive scripts for processing raw data and uniform coding of several variables
  • EPI: useful data library code that processes raw CPS data, creates uniform extracts, and analyzes data
  • IPUMS: clear variable-specific web pages providing a model for how variables should be documented
  • NBER: helpful scripts for transforming BLS/Census flat files into Stata data, as well as the resourceful NBER MORG data files
