Two comparisons, both shown. The national basis ranks Mendocino County against every scored U.S. county — its percentile band above is a relative national standing, not a condition. The in-state basis ranks it against California's other counties (rank and percentile only — bands aren't meaningful within a single state). A county can stand out in its own state while sitting mid-pack nationally. Neither is a forecast.
Mendocino County scores 45.3 on the national CAERI basis — 2058th of 3,142 scored U.S. counties, placing it in the 25th–50th band nationally by percentile, with a high-confidence rating. Within California it ranks 47th of 58 counties (20th in-state percentile). The score summarizes how concentrated local employment is in AI-exposed occupations against the economy's measured capacity to adapt; these are relative-standing bands, not a projection of local job change.
Direct occupational exposure stands at the 36th national percentile. The largest concentrations of locally estimated employment in high-exposure occupations are office clerks, general, bookkeeping, accounting, and auditing clerks, elementary school teachers, except special education. The share of exposed-industry jobs held by workers under 25 is 7% — near the state median of 7%; research on AI-era payrolls finds early-career roles in exposed work are where hiring patterns shift first, so this share indicates how soon exposure could be felt, not how large it is.
The share of exposed-industry jobs held by workers 55 and over is 33% (well above the state median) — a higher share historically means slower workforce adjustment when industries restructure. Fiscal sensitivity ranks at the 90th percentile among California's counties. Census of Governments data shows state aid at 26% of this county's general revenue (well below the state median), and wage- and consumption-sensitive streams (sales, income, and similar own-source taxes, where levied) at 34% of own-source revenue. Property taxes, which respond to economic change more slowly, are counted separately and are not part of that sensitive share. How this state's aid formulas and tax structure carry economic change into local budgets is covered in the state-specific fiscal analysis available to subscribers. All county occupation figures on this page are model-based ESTIMATES with the confidence rating shown above.
Across all 178 high-exposure occupations (top quartile of ensemble exposure) with estimated local employment, Mendocino County has an estimated 6,184 jobs — 20.4% of county employment — carrying an estimated $423M annual wage bill in high-exposure work. The five largest:
| Occupation | Est. local employment* | Exposure (0–1) | Median wage (area) |

| Mendocino County | California median | |
|---|---|---|
| Share of exposed-industry jobs held by workers under 25 (entry rung) | 7.1% | 7.1% |
| Share of exposed-industry jobs held by workers 55+ (adjustment friction) | 33.1% | 28.8% |
