These are counts of establishments physically operating in the county, not listings, so they are the supply side a feasibility study measures demand against. County Business Patterns counts private establishments with paid employees in March 2023, while the Quarterly Census of Employment and Wages above counts every unemployment-insured employer, public ones included, as a 2024 annual average, so the two establishment and employment counts differ.

The county's own community in the status book, unincorporated Clark County (community 460258), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Clark County in radon zone 1, a predicted average indoor radon screening level greater than 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. 100.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
