Self-reported work-limitation data: what they can and cannot tell us.

Despite their widespread use in the literature, the Current Population Survey (CPS) and similar surveys have come under attack of late. We put the criticisms in perspective by systematically examining what the CPS data can and cannot be used for in disability research compared to the National Health Interview Survey. On the basis of our findings, we argue (1) that the CPS can be used to monitor trends in outcomes of those with disabilities and (2) that the dramatic decline in the employment of people with disabilities we describe in the CPS during the 1990s is not an artifact of the data.
