Derived statistics

  • ACS-based CBSA estimates are aggregated from ZCTA (ZIP) values for ZIPs in the CBSA; totals may differ from official CBSA ACS tables.
  • Health metrics (when shown) are derived from county-level CDC PLACES.
  • Median age, household size, and mean commute time (when shown) are estimated as population-weighted averages of ZIP values.
  • If a CBSA unemployment series is unavailable, unemployment is derived as a population-weighted average of member counties.
  • Population density is computed as population ÷ land area.

Data accuracy & methodology

CBSA pages use 2020–2024 ACS 5-year ZCTA (ZIP) estimates aggregated across ZIPs in the CBSA, plus other public datasets when available (see Sources). Aggregated ZIP-based totals can differ from official CBSA ACS tables. Health estimates are derived from county-level CDC PLACES data when available.
