UHC Data Portal Updates: Aug 2023

UHC, August 28, 2023

During the summer, UHC R&D Team focused primarily on Data Portal developments by adding new tags to datasets to make the platform more accessible and user-friendly. The portal has also been updated with new datasets.

  • New Dataset Added

•              Gentrification measures: Gentrification is a commonly discussed topic. There are no universally accepted definitions of gentrification. The UHC gentrification working group developed a measure that uses shifts in affordability and economics and classifies census tracts as ineligible to gentrify, not gentrified, gentrification, and intense gentrification. The gentrification measure included on the UHC Data Portal uses census tracts in the top 25th percentile of median household income as being ineligible to gentrify (recommended definition) and represents gentrification from 2010 to 2020.

•              More information about how the gentrification measure was created and background about gentrification, see the UHC Methods Brief “A MEASURE OF GENTRIFICATION FOR USE IN LONGITUDINAL PUBLIC HEALTH STUDIES IN THE US” ( https://drexel.edu/uhc/resources/briefs/Measure-of-Gentrification-for-Use-in-Longitudinal-Public-Health-Studies-in-the-US/ ).

Please note that UHC has gentrification from 1990 to 2000 and 2000 to 2010 that can be requested after completing a data use agreement. There are also definitions for “ineligible to gentrify” using the 50th (more conservative) and 10th (more liberal) percentiles for sensitivity analysis. E-mail UHCdata@drexel.edu for information about accessing additional data.

As part of its ongoing efforts, UHC Research and Data Core is working to expand the types of data available from its repository. Reach out to UHCdata@drexel.edu with any specific requests. To ensure the accuracy of all data, the UHC Research and Data Core will update it as soon as possible.

UHC Data Portal Updates: July 2023

UHC, June 28, 2023

New datasets and updated documents

Added data will be updated regularly based on ongoing projects, with an emphasis on datasets useful for multiple projects.  Additional data are available in the UHC repository, which are not currently available on the portal. During the past month Research and Data core had more focus on updating documents for the current datasets rather than adding new datasets to the portal. Below are the list of updated documents and/or summary files for previous month.

  • Updated documents and/or summary files

·         Average percent impervious National Land Cover Dataset

·         Percent Green National Land Cover Dataset (NLCD) Contiguous US

·         American Community Survey 5-year_ZCTA (2015-2019)

·         Census Tracts 2020 Philadelphia Reading Camden CSA

·         ZCTA 2020 Philadelphia Reading Camden CSA

Links to documentation for Census Tracts 2020 and ZCTA 2020 are to the same document which addresses Census 2020 boundaries in general. This document includes information about special land use/low population tracts and includes summary information about tract differences between 2010 and 2020.

As part of its ongoing efforts, UHC Research and Data Core is working to expand the types of data available from its repository. Reach out to UHCdata@drexel.edu with any specific requests. To ensure the accuracy of all data, the UHC Research and Data Core will update it as soon as possible.

UHC Data Portal Updates: May 2023

UHC, May 1, 2023

 

  • New datasets and updated documents.  

Data added to the portal will be updated on a regular basis, based on ongoing projects, focusing on datasets that are useful for multiple projects. The UHC repository includes additional data that is not currently on the portal. The following is a list of new datasets and updates that have been added to the portal over the last month 

New Datasets 

  • ZCTA 2010 spatial file for metropolitan Philadelphia, Reading, Camden CSA (SAS, ZIP, SHP, CSV) and Variable list 
  • ZCTA2020 spatial file for metropolitan Philadelphia, Reading, Camden CSA (SAS, ZIP, SHP, CSV) and Variable list 

For information about ZIP Code Tabulation Areas (ZCTAs) see Policy Map’s blogpost 

  • PHL neighborhoods DSPH: 2010 tract (ZIP, SHP, CSV) and Variable list 
  • Percent Green National Land Cover Dataset (NLCD) Contiguous US (SAS CSV) and variable list : Percent green from 30 m resolution land cover data for 2010 tracts for contiguous US 2016 & 2019 
  •  American Community Survey 5-year (2017-2021) ZCTA (SAS, CSV) and variable list. 

 

Updated Dataset 

 

  • Census Tracts 2010 Philadelphia Reading Camden CSA : Tract boundaries were updated to include DSPH Neighborhoods. CSV, SAS, SHP files and documentation updated. 
  • Variable list for Census 2000 for main and population dataset updated. 

 

Updated Documentation  

 

  • Average percent tree cover NLCD, Average percent impervious NLCD and percent green: documentation updated to include contiguous US files. This documentation includes percent green and assumes in RECVD for 2006-2011. 

 

  • Hands-on experience with data access, analysis, and interpretation in a group setting  

The UHC Research and Data Core will be facilitating a workshop that aims to introduce researchers to the UHC Data Portal, and focus on three commonly utilized residential segregation measures: the Dissimilarity Index, the Gini Index, and the Index of Concentration at the Extremes (ICE). While measures of structural and institutional racism vary, residential segregation remains a consistent and often utilized measure to capture, at the neighborhood level, the continuum of disadvantage and privilege. Enabling researchers to measure and map various health and social inequities, often with a specific eye towards placed-based solutions ranging from interventions and policies targeted at health equity, is key. Workshop attendees will be introduced to the three measures for the city of Philadelphia, and shown how they can be used to conduct exploratory spatial data analyses. Finally, workshop attendees will have an opportunity to have brief hands-on experiences in data access, analysis, and interpretation in a group based setting.    

 

The UHC Research and Data Core is actively working to expand which data from the repository are available; reach out to UHCdata@drexel.edu with any specific requests. All available data will be updated as possible by the UHC Research and Data Core.
