Education data

These data provide disability-specific earnings referenced by gender, education level, and disability status.  Education earnings for persons without a work disability are based on the latest year of data from the Current Population Survey (CPS).  Earnings for persons with a work disability are derived by using the average differentials between persons with and without a disability over multiple years of the CPS.  The differentials (which are specific to gender, educational level, and disability status) are applied to the latest year's nondisabled averages to derive disabled averages.

Sources are also provided for earnings from the American Community Survey and the 2000 Decennial Census.  These are specific to disability type and are referenced by gender, education level, and disability status.
