UDS Mapper: New Features and Updates

Map showing Health Center Program Grantee Dominance by ZCTA, 2011, for portions of Indiana, Ohio, and Kentucky.

UDS Mapper, a HRSA-funded project directed by the Robert Graham Center, helps inform users about the current geographic extent of U.S. federally (Section 330)-funded Health Center Program (HCP) grantees. It is one of many apps HealthLandscape has developed to visualize unique data sets.

Check out these new features and updates:

Individual Health Center Program Grantee Service Areas

In the Explore Service Area box (formerly the Define Service Area box), there are three optional functions:

  • By Geography: View patient and demographic data by Zip Code Tabulation Area (ZCTA).
  • New! By Patient Origin: Select individual HCP grantees and see their service areas according to patient-reported Zip Codes.
  • New! By Distance: Determine the potential service area included within a driving time or distance to a given point.

New! Population Indicator Sliders

In the Map Elements box, we’ve added a fourth tab, Population Indicators. Use this new feature to visualize the following population-based data by ZCTA:

  • % of population in poverty
  • % of population low-income (less than 200% of poverty)
  • % of population not employed
  • Low birth weight rate
  • Age-adjusted mortality rate (per 100,000)
  • % of adults ever told have diabetes
  • % of population uninsured
  • % of adults with no dental visit in past year
  • % of adults who have delayed or not sought care due to high cost
  • % of adults with no usual source of care

Data sources: American Community Survey (ACS) 2010 5-year and 3-year estimates; CDC Behavioral Risk Factors Surveillance Survey (BRFSS) 2010; CDC Vital Statistics 2009; CDC Area Resource File 2011

Use the indicator slider to adjust the rate. You will see the ZCTAs where the rate is greater than or equal to the number that you set on the slider.

Enhanced Rollovers

Roll your mouse over a ZCTA and see a list of up to five HCP grantees with the share of total HCP patients each center sees.

Most Current Data

UDS Mapper uses the most current data sets available, including the 2011 UDS data and the 2006-2010 ACS demographic estimates.
