Among people legally eligible for expungement, just 6.5% obtain it within five years of eligibility.
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.
People 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.
