Key findings from our county-level economic dataset spanning eight major industry sectors across the United States.
Concentrated in coastal metros and emerging tech hubs. Highest GDP per capita of all sectors.
Midwest and Southeast industrial corridors. Steady growth with pockets of rapid automation-driven expansion.
Dominated by New York, Charlotte, and Chicago metros. High-value but concentrated employment.
Fastest-growing sector nationally. Distributed broadly with clusters around research hospitals and biotech hubs.
Texas, North Dakota, and Gulf Coast. Volatile but high-GDP impact with renewables reshaping the landscape.
Great Plains and Central Valley anchors. Lower GDP per capita but essential for food system stability.
Coastal resorts, national parks, and urban destinations. Cyclical but resilient long-term growth.
DC metro, state capitals, and military bases. Stable employment base with moderate GDP contribution.

US county boundary data from the US Census Bureau, rendered as TopoJSON for efficient browser delivery. The map uses Leaflet.js with CartoDB dark tiles for a professional dark-theme basemap.
Each county carries a seeded economic profile: GDP per capita baseline, annual growth rate, dominant industry sector, population, and employment. The model supports 2010–2024 time-series projection.
Three colour modes — Industry classification, Growth rate heatmap, and GDP per capita gradient. A time slider animates economic evolution. Click any county for a detailed profile with rankings and peer comparisons.
