This layer displays cancer screening and risk factor information from the State Cancer Profiles data – a collaboration between the Center For Disease Control and Prevention (CDC) and National Cancer Institute (NCI). County level model-based estimates are calculated by combining responses from the Behavioral Risk Factor Surveillance System (BRFSS) and the National Health Interview Survey (NHIS), and uses the U. S. Census Small Area Estimates (SAE) methodology to estimate data for non-response areas. Low (-95%) and High (+95%) confidence intervals are also included in the popup. The width of a confidence interval depends on the amount of variability in the data. Narrow confidence intervals tend to imply greater certainty in the estimate, while wide confidence intervals tend to imply more variability in the data and could mean there is less certainty. For more information visit the State Cancer Profiles Methodology Page.
Real-time Air Quality Index (AQI) – Ozone and Particulate Matter
This US EPA feature layer is updated hourly and reflects the latest hour of air quality data received from each monitoring site that reports to AirNow. The concentration and AQI values are for Ozone and Particulate Matter (PM) only. Air quality index ranges from 0-5,000 with higher values indicating worse air quality.
Rural-Urban Commuting Zones
The USDA, Economic Research Service’s (ERS) Rural-Urban Commuting Area (RUCA) codes are a classification scheme allowing for flexible, census tract delineation of rural and urban areas throughout the United States and its territories. RUCA codes were designed to address a major limitation associated with county-based classifications; they are often too large to accurately delineate boundaries between rural and urban areas. The more geographically-detailed information provided by RUCA codes can be used to improve rural research and policy—such as addressing concerns that remote, rural communities in large metropolitan counties are not eligible for some rural assistance programs.
The RUCA codes consist of two levels. The primary RUCA codes establish urban cores and the census tracts that are the most economically integrated with those cores through commuting. The secondary RUCA codes indicate whether a census tract has a strong secondary connection (through commuting) to an even larger urban core. For more information, visit the “RUCA website” here.
Health Insurance Marketplace Enrollment, 2025
Area Deprivation Index by Census Block Group
The 2023 Area Deprivation Index is now available! The ADI map displays rankings of neighborhoods by socioeconomic status disadvantage in a region of interest (e.g. at the state or national level). It includes factors for the theoretical domains of income, education, employment, and housing quality. It can be used to inform health delivery and policy, especially for the most disadvantaged neighborhood groups. The 2023 ADI was constructed using the 2019-2023 5-year estimates from the US Census’ American Community Survey.
