Current Population Survey

The US survey instrument (March Supplement and May/Outgoing Rotation Group extracts) whose differing sample sizes and a documented pre-1980-census push to improve coverage of low-skill Black men are the central mechanism in the Clemens & Hunt argument that George Borjas's measured Mariel Boatlift wage effect is a compositional-sampling artifact rather than a real labor-market response. Borjas's own reply uses the survey's year-to-year figures against that argument, showing the Black-share jump concentrated in a single 1978-to-1979 transition, decoupled in time from the wage decline he attributes to the Boatlift.
