Hale’s goal as an employee of BLS is to find/develop a survey to enable measurement of the employment experiences of persons with a disability as it is defined by the ADA.  The CPS, however, does not use this definition, nor is this definition the best one to use when assessing lost earnings.  Other key criticisms in the article deal with the validity of the first work disability question (limited in the amount or kind . . .) and the presence of persons with a temporary disability. 

There is no official government position against use of the CPS to define work disability. In fact the Census Bureau regularly generates cross-tabulations of this data and publishes it on its web site.  In fact, two noted former Census officials (McNeil and Miller) have authored affidavits to the validity of CPS for measuring work disability.
