Labor Force Participation Rate

Primary source

All values come directly from BLS via FRED (CIVPART). We do not modify, smooth, or interpolate published values.

The percentage of the working-age US population that is either employed or actively seeking work. Structural measure of labor market engagement. Declines from aging demographics and pandemic effects; used alongside unemployment rate for a fuller labor picture.

Update schedule

Monthly — we refresh daily; new values typically appear on the upstream release calendar.

We gate dateModified updates to actual value changes (threshold: 0.01% absolute or 0.5% relative) to prevent freshness spoofing. If the upstream value hasn't moved, we don't claim we updated the page.
