Two comparisons, both shown. The national basis ranks New Castle 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 Delaware'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.

Pillar breakdown — national percentile ranks

What this means for New Castle County

New Castle County scores 60.7 on the national CAERI basis — 502nd of 3,142 scored U.S. counties, placing it in the 75th–90th band nationally by percentile, with a high-confidence rating. Within Delaware it ranks 1st of 3 counties (83th 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 94th national percentile. The largest concentrations of locally estimated employment in high-exposure occupations are customer service representatives, office clerks, general, software developers. The share of exposed-industry jobs held by workers under 25 is 6% — well below the state median of 8%; 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 27% (below the state median) — a higher share historically means slower workforce adjustment when industries restructure. Fiscal sensitivity ranks at the 64th percentile among Delaware's counties. Census of Governments data shows state aid at 15% of this county's general revenue (well above the state median), and wage- and consumption-sensitive streams (sales, income, and similar own-source taxes, where levied) at 3% 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.
