Live federal series. County values pulled direct from Census ACS5 2023: B25064 median gross rent, B25071 rent-as-%-HH-income, B19013 median HH income, B01003 population.
State rollup = pop-weighted mean of county values (B01003 weights). Rent Index = county_rent / national pop-weighted mean × 100. US = 100.
Pending domains: D2 Mortgage (FRED MORTGAGE30US + ACS B25077), D3 Insurance (NAIC + III), D4 Childcare (DOL NDCP — killer feature), D5 Composite Burden Ratio.
Calibration audit (v1.1): 1062/3212 D3 HO counties at lower clamp (low-rent floor); 65/152 D4 cc-county-adj at lower clamp. Clamp [0.7,1.5] working as designed.

National choropleth covering all 50 states, DC, Puerto Rico, and 3,142 US counties at county-level resolution. Tract-level layer deferred to TSCI v2.1+ — see migration playbook for sprint sequence.

Owner monthly nut: owner_cost + cc_m + ho_ins/12

TSCI Composite Index (ti): weighted aggregate of rent burden, owner burden, P/I, childcare share — pop-weighted at state/national level.
State pop-weighted aggregation across counties uses ACS B01003 population. Counties with suppressed values are excluded from aggregation. Insurance clamps documented in Calibration_Audit sheet: 33.1% of states at HO insurance floor (NAIC published-precision limit); 42.8% of childcare-counties hit lower clamp in NDCP.

Census ACS5 2023 covers 2019-2023 conditions (released Dec 2024). DOL NDCP base year 2018, inflated to 2023 dollars. NAIC HO-3/HO-4 from 2022 annual report. Note: ACS5 2024 release expected Dec 2026.
• Currently county-level only. No tract resolution layer. See TCBI v3.0.0 for what tract resolution looks like — TSCI tract layer is the next planned major release.
• Childcare is the only domain with universal county coverage. Insurance is state-only.
• 8 states (AR, CT, IN, MO, NM, PA, VT) plus Puerto Rico are proxy-derived for one or more childcare slots.
• Composite weights calibrated against a synthetic family-of-4 reference budget.
