State-by-State Empirical Inventory (Deduplicated GEOID Household Summation)

Every state and regional rate below is calculated strictly from summed household numerators divided by summed household denominators (R_G = ΣY_i / ΣN_i), never by averaging neighborhood percentages. Click any row to inspect its cities.

Sources and methods

Household internet access is reported for entire Census block groups. Overlap with a historical HOLC polygon does not estimate the rate inside that polygon or show a causal effect.

The full atlas preserves the Pleasant Hill neighborhood, city, county, state and project region views. City and county benchmarks use separate published records; project region rates use summed state household counts.
