Affordable home price assumes the industry's average earner uses 30% of gross income for housing, with a 30-year mortgage at 7%, 5% down, $2,500/yr taxes & insurance, and 0.5% PMI. Adjust the Section 3 calculator for other terms. Affordable rent is 30% of monthly gross pay.

Section 5

Wages by Occupation

Selected essential-worker occupations for the MSA or nonmetropolitan area containing this county — jobs, the 10-year change, wages, and the housing each typical earner can afford. Both jobs counts and wages are reported at the MSA / nonmetropolitan-area level (BLS does not publish OEWS at the county level), so every county inside the same area shows the same numbers. For county-accurate employment totals, see Section 4 above.

Affordable home price uses the same Section 3 formula (30% housing budget, 30-year mortgage at 7%, 5% down, $2,500/yr T&I, 0.5% PMI). Affordable rent is 30% of monthly wages. Negative job-change values are shown in red parentheses. A "prior-year code differs" note flags occupations whose SOC code changed between the two vintages (2010 SOC → 2018 SOC) — the change estimate is best-effort.

Source: BLS OEWS May 2025 (10-year change vs. May 2015). Jobs counts and wages reflect the MSA or nonmetropolitan area containing this county, not the county alone — OEWS is not published at the county level.

Methodology & sources

All figures derive from the 2024 American Community Survey 5-year estimates. State and national comparisons are population-weighted aggregates of county-level estimates (an approximation; ACS publishes its own state and national medians which can differ slightly).

The affordability calculator uses a 30% housing-budget rule with a 30-year mortgage. Defaults are 7% interest, 5% down, $2,500/year taxes and insurance, and 0.5% PMI — adjustable above.
