Data Repository

Urban health word cloud

 The Urban Health Collaborative Research and Data Core supports work that characterizes health in cities and conducts research on health determinants and the impact of policies. As part of its activities, the Core compiles data on health determinants and outcomes for the Philadelphia region. The Core is actively working to expand and update available data, in the region and beyond.

What data are available?

The UHC Research and Data Core may have the data you need, whether you're looking for data to support projects, pilot analyses or grant writing, or in-depth studies. Our Summary of Data document has detailed descriptions on available data.

Data have been compiled on vital records, inpatient and outpatient/ambulatory care discharge data for Pennsylvania.

Access the UHC Data Portal

Selected data from the UHC Data Repository can now be accessed via the online UHC Data Portal. Currently, this tool is available to UHC faculty and staff as well as students who either have UHC affiliations or work with UHC faculty on an APE, ILE, or other data analysis project.

Data are currently available in the following categories:

  • Demographics
  • Health Outcomes
  • Environmental Hazards
  • Social Environment
  • Built Environment
  • Natural Environment 
  • Spatial Boundaries

Updates on newly added categories and data sets can be found on our UHC Data Portal News page or in the UHC monthly newsletter. If you have any questions or feedback, please contact us at

How to request data

UHC faculty, staff, and students can obtain data directly from the UHC Data Portal. If data you need is not available on the UHC Data Portal, please contact with a summary of the data you need.

Non-UHC Drexel faculty, research staff, post-doctoral fellows, and students can request data from the UHC by submitting a proposal that briefly describes the project to The proposal should be between two and three pages and should include the following information:

  1. Working Title
  2. Project lead and list of collaborators (Please note that if the lead is a student, a faculty mentor should be part of the project team and a letter of support from the faculty mentor should be included, and date that the student anticipates graduating.
  3. Contact information for the project lead (email address and/or phone number).
  4. Background/rationale (1-2 paragraphs).
  5. Research Aims (objective) and Hypotheses (if appropriate).
  6. Summary of data needed including brief description. For example: dependent and independent variables, covariates, spatial data, etc., as appropriate to the research question. Please include the preferred spatial coverage and data year(s). See UHC Data Summary for information on data available.
  7. Brief analytical plan
  8. Timeline
  9. Proposals should also indicate whether GIS or data management/data analysis assistance from the UHC will be needed. Please specify the tasks that will be required by UHC staff (e.g. creation of spatial variables, statistical analysis).

The data information request sheet outlines the review process and next steps after your proposal is approved.
