County data sources and method

Sources and vintages

• Census county Gazetteer: 2026.
• Census ACS B21001, veteran population: 2020-2024 ACS 5-year.
• Census ACS B21002, period of service: 2020-2024 ACS 5-year.
• Census ACS B21100, disability ratings: 2020-2024 ACS 5-year.
• VA GDX, county spending: FY2025.
• VA facilities cache: 2026-09-25.
• Local office directory: repository snapshot b62c9b773282.
• Regional office registry: repository snapshot b62c9b773282.
• Census county adjacency: 2024.
• Census ZIP Code Tabulation Area to county relationships: 2020.

Benefits pages link each program to its official source and checked date. Missing facts remain unavailable, never zero. Connecticut uses the nine Census planning regions; older VA county figures are not allocated to those regions.

Survey estimates and comparisons

ACS 2020-2024 margins of error use a 90 percent confidence level. Estimates and margins are rounded for reading. A coefficient of variation above 30 percent is marked as rough and excluded from comparisons. State and national estimates come from Census summary levels 040 and 010, not sums of counties. Equal rounded shares do not establish statistical equality; comparisons do not test statistical significance.

Rating shares use all civilian veterans as the denominator. Age shares combine male and female B21001 counts in each age band. Women veterans use the female total. Age-count margins combine by root-sum-of-squares; percentage margins use the ACS subset formula, with the sum formula when subtraction gives a negative squared margin. Missing margins prevent comparison.

Population ranks order county and equivalent ACS point estimates within each state. Equal counts share a rank; missing counts reduce the comparison group. A rough county total is not ranked. Survey uncertainty can change the order. Service-era counts keep the original, mutually exclusive B21002 categories, including multi-era groups.

Offices and distances

Distances are measured in a straight line from the center of the county, using the Census internal point. They are not driving distances or travel times. The first and second medical centers and Vet Centers use distinct facility IDs from the cached VA sandbox response, dated 2026-09-25. This cache may differ from current VA listings. Confirm locations and services with VA before traveling.

Regional office candidates describe state locations, not verified county claims jurisdiction. Office matches use county names; a blank office county is matched only where at least 80 percent of its ZIP area falls in one county. County adjacency uses shared boundaries; nearest-county links use internal-point distances.

VA spending

VA GDX FY2025 figures are county totals for one fiscal year, not individual benefit amounts. They do not establish what a veteran receives or could qualify for.

Local summary paragraphs

The summary paragraph was drafted by AI from the facts on this page and checked automatically against them.

This disclosure applies where a local summary is shown. Checks reject unsupported numbers, names and prohibited claims, but are not a human fact check. A missing, invalid or stale summary is omitted. The facts and office details remain available without a summary.
