Overview
Background Screening & Employment Verification companies vet candidates and workers through criminal, credential, identity, and employment-history checks to support hiring decisions and ongoing workforce compliance. The market is led by dedicated screening firms (HireRight, Sterling, First Advantage, Checkr) alongside the employment-screening arms of the major credit bureaus.
Demand is tied to hiring volume and a steadily expanding web of compliance requirements, with technology and instant-verification data the basis of competition. It has consolidated heavily, including several private-equity take-privates of the leading screening platforms.

The ~$6.2B is the investigation-and-background-check industry proper (561611). It corrects an earlier ~$21B that had wrongly folded in consumer credit bureaus (Experian/Equifax/TransUnion), a different business entirely. Tech-enabled screening (Checkr, Sterling, HireRight) is partly classified with software, so the employment-screening slice a buyer targets is a growing share of this figure rather than its whole.

Geographic concentration
Florida stands out as the clearest concentration at over 1.6 times its expected share of screening and investigation firms, on the back of the state's unusually large private-investigation, tenant-screening, and insurance-fraud economy. It is the one genuine hotspot; elsewhere the work tracks service-economy hiring and follows population.
