<br/><br/> The underlying data from which the U.S. unemployment rate, labor-force participation rate, and duration of unemployment are calculated contain numerous internal contradictions. This paper catalogs these inconsistencies and proposes a unified reconciliation. We find that the usual statistics understate the unemployment rate and the labor-force participation rate by about two percentage points on average and that the bias in the latter has increased over time. The BLS estimate of the average duration of unemployment substantially overstates the true duration of uninterrupted spells of unemployment and misrepresents what happened to average durations during the Great Recession and its recovery.
