Abstract

Laws permitting the expungement of criminal convictions are a key component of modern criminal justice reform efforts and have been the subject of a recent upsurge of legislative activity. This debate has been almost entirely devoid of evidence about the laws’ effects, in part because the necessary data (such as sealed records themselves) have been unavailable. We were able to obtain access to deidentified data that overcomes that problem, and we use it to carry out a comprehensive statewide study of expungement recipients and comparable non-recipients. We offer three key sets of empirical findings. First, among those legally eligible for expungement, just 6.5% obtain it within five years of eligibility. Drawing on patterns in our data as well as interviews with expungement lawyers, we point to reasons for this serious “uptake gap.” Second, those who do obtain expungement have extremely low subsequent crime rates, comparing favorably to the general population—a finding that defuses a common public-safety objection to expungement laws. Third, those who obtain expungement experience a sharp upturn in their wage and employment trajectories; on average, within two years, wages go up by 25% versus the pre-expungement trajectory, an effect mostly driven by unemployed people finding jobs and very minimally employed people finding steadier or higher-paying work.
