Project Description

Summary:  View help for Summary This dataset contains measures of the number and density of social services, such as community centers, child and youth services, services for the elderly and persons with disabilities, meal delivery programs, substance abuse counseling, day care services, and more per United States Census Tract or ZIP Code Tabulation Area (ZCTA) from 1990 through 2021. The dataset includes four separate files for four different geographic areas (GIS shapefiles from the United States Census Bureau). The four geographies include:
  • Census Tract 2010
  • Census Tract 2020 
  • ZIP Code Tabulation Area (ZCTA) 2010
  • ZIP Code Tabulation Area (ZCTA) 2020 
Information about which dataset to use can be found in the Usage Notes section of this document.

Methodology

Data Source:  View help for Data Source Business establishment data were taken from the National Establishment Time Series (NETS) database produced by Walls and Associates (2022) using archival establishment data from Dun & Bradstreet. NETS is a time-series database based on snapshots taken every January of the full Duns Marketing Information (DMI) file of over 80 million private for-profit and nonprofit establishments and government agencies. These snapshots used the DMI file to determine which establishments were active in January of each year from 1990 to 2021. This longitudinal data source classifies establishments by Standard Industrial Classification (SIC) code and provides detailed business microdata and address history (D. Walls & K. Perez, personal communication, October 4, 2022). We determined each establishment’s Census Tract or ZCTA for each year by mapping its latitude and longitude to the 2010 and 2020 TIGER/Line shapefiles from the US Census Bureau (United States Census Bureau, 2021a, 2021b). There are four versions of this dataset: Census Tract 2010, Census Tract 2020, ZCTA 2010, and ZCTA 2020. Each dataset is standardized to a single US Census geography; as a result, the variables are commensurable across all of the years in each dataset.The population denominator for the per capita density variables came from the American Community Survey (ACS) or Decennial Census (United States Census Bureau, 2015a, 2015b, 2015c, 2016, 2017, 2020, 2023a). ACS data were used for available years; Decennial Census data were used when ACS data were not available (1990-2005, 2020-2021). A detailed description of the denominator used in the per capita density variables can be found in the Appendix of this document.Data for the land area denominator came from the land area of the Census Tract or ZCTA from the 2010 or 2020 TIGER/Line shapefiles (United States Census Bureau, 2021a, 2021b). The IPUMS NHGIS crosswalks (Manson et al., 2023) were used to normalize data longitudinally.
