Methodology: Statistics are compiled from aggregated official state registry records and refreshed monthly. City figures count the city listed on each registry record. Per-capita rates use 2020 U.S. Census populations. Aggregated counts can exceed what public registry websites display because some classification levels are excluded from public searches. Figures are estimates and change daily as registries update — always verify individual records with the official state registry.
