Notes:
Created by statecancerprofiles.cancer.gov on 03/21/2026 6:11 am.
Φ Rural–urban county classifications are based on the 2023 USDA Rural–Urban Continuum Codes (except for Connecticut Counties which use 2013 codes). State-level cancer rates for rural areas are calculated using cancer cases registered exclusively in rural counties, while state-level cancer rates for urban areas are calculated using cases registered exclusively in urban counties.
Puerto Rico is treated as urban because over 90% of the population lives in urban areas.
Source: Demographic data provided by the Census Bureau and the American Community Survey.
For more information about Education: At least bachelor's degree, see the dictionary.
Note: This website still uses Connecticut counties instead of planning regions for consistency of geographies across data topics. If/when all data sources have new planning regions, then this website will switch to using them.
Data for United States does not include Puerto Rico.
