The traffic proximity indicator is based on AADT count divided by distance in meters from the Census
block centroid. The proximity score is based on the traffic within a search radius of 500 meters (or
further if none is found in that radius). This distance was selected to be large enough to capture the
great majority of road segments (with traffic data) that could have a significant impact on the local
residents, balanced against the need to limit the scope due to computational constraints. The closest
traffic is given more weight, and the distant traffic is given less weight, through inverse distance
weighting. For example, traffic 500 meters away is given only one tenth as much weight as traffic 50
meters away.
Influenza Vaccination by County, Adult (2021)
This layer displays immunization rates for seasonal influenza among adults aged 18 and older. Data are from the Centers for Disease Control and Prevention (CDC) FluVaxView data portal. The county-level estimates within FluVaxView are derived from responses to the 2021 BRFSS.
EJ Screen RMP Facility Proximity
The RMP facility proximity is reflective of the total count of RMP facilities in each block group within 5
km of the average resident in a block group, divided by distance, calculated as the population-weighted
average of blocks in each block group
Influenza Vaccination by Vaccination Setting (Non-Medical Setting)
This layer displays the proportion of the county population immunized for influenza aged 18 years or older who have received the vaccination in a non-medical setting. Data are from the Centers for Disease Control and Prevention (CDC) FluVaxView data portal. The county-level estimates within FluVaxView are derived from responses to the 2021 BRFSS.
Cancer Incidence Rates by County, 2016-2020
Layer displays cancer incidence rates (all sites) per 100,000 population by state and county. Additional map layers from this update include incidence rates for breast cancer, colon and rectum cancer, lung cancer, prostate cancer, and more.
Occupied Housing Units
This layer displays information from the US 2020 Decennial Census, which provides occupied housing units for all geographic areas. An occupied Housing is when a person or group of persons is living in it at the time of the interview or if the occupants are only temporarily absent, as for example, on vacation. This data was released as part of the decennial census in April 2020. Learn more about this dataset at Census.gov.
Population Living in Rural Areas
This layer displays percent of population living in rural areas as of 2020. This data was released as part of the decennial census in April 2020. Learn more about this dataset at Census.gov.
Population Living in Urban Areas
This layer displays percent of population living in urban areas as of 2020. Urban areas are identified using population density, count, and size thresholds. This data was released as part of the decennial census in April 2020. Learn more about this dataset at Census.gov.
Vacant Housing Units
This layer displays information from the US 2020 Decennial Census, which provides vacant housing units for all geographic areas. A vacant Housing Unit is when no one is living in it at the time of the interview, unless its occupants are only temporarily absent. This data was released as part of the decennial census in April 2020. Learn more about this dataset at Census.gov.
Air Quality – Ozone Levels (O3) by Census Tract, 2019
This layer displays the daily average concentration of ozone and the percentage of days with concentrations of ozone above the National Ambient Air Quality Standard (NAAQS) of 0.075 parts per million in 2019.
