Business Employment Dynamics

The governmental BED standing age tables publish establishment-age classes, March observation periods, total establishment counts, and employment by establishment age for supported national/state industry tables. They directly supply externally observed operating-age distributions, not firm formation age.

BED's standing annual-opening-cohort table publishes opening cohort, March observation period, surviving establishment count, survival rate since birth, and prior-year conditional survival rate. Cohort and observation periods pin the survival horizon; this is establishment survival, not firm-level legal continuation, and is delivered by downloadable tables rather than a verified survival API.

BED's standing age tables publish total establishment counts and establishment net change by age, while the coordinated BED series publish openings, closings, births, and deaths. Together they directly distinguish net stock change from gross entry and exit for supported geography, industry, and observation periods.

BED publishes establishment openings, closings, births, and deaths as distinct documented classes, with count/job levels and rates by supported geography, industry, period, and seasonal-adjustment status. This directly supports establishment operating-entry and exit trends, but not firm startup or firm-death trends.
