Data enrichment is an ArcGIS service function that enhances your location data, such as an address, with information about the people and places nearby. It is performed by the GeoEnrichment Service in Esri products like ArcGIS Online, ArcGIS Enterprise, ArcGIS Pro, ArcGIS Business Analyst, ArcGIS Platform, and more.
The information provided from data enrichment can help you to perform location-based analysis and make decisions. For example, when you select an area on a map to enrich, the GeoEnrichment Service can retrieve information about that region, such as local spending habits, household wealth, or the average number of children per household. This might help you to produce projected results like sales territories, school districts, or voting precincts.
You can use data enrichment to:
- Choose from over 15,000 demographic analysis variables in more than 170 countries.
- Add location-based context about the people and places affected by your data.
- Learn about consumer spending habits, identify markets, and explore demographic traits to understand communities.
- Use location analytics to formulate business and policy decisions.
Typically, you perform data enrichment in an Esri product. Some products require that you sign in with an ArcGIS account that has GeoEnrichment privileges to perform data enrichment; this may consume credits or generate pay-as-you-go costs.
How data enrichment works
Data enrichment uses your input location data and selected analysis variables (also called attributes) and returns the requested information for that region.
When data enrichment is used in an ArcGIS mapping application, the result creates a map layer in the app. The GeoEnrichment Service uses the best available apportionment method to determine the value of each variable on the map layer.

To apportion data correctly, the GeoEnrichment Service relies on settlement points, which are a weighted estimate of population density (population per square mile/km).
There are several types of settlement points. Not every country or region produces settlement points in the same way, and depending on the country or region, a settlement point is one of the following:
|Settlement point type||Description|
Residential Address Settlement Points
Government-Sourced Grid Settlement Points
Census Block Centroid Settlement Points
Residential Generic Building or Parcel Footprints (GF) Settlement Points
All Building Footprints Settlement Points
Esri Raster Based Settlement Points
WorldPop.org Raster Based Settlement Points
Each country or region for which Esri provides demographic data uses settlement points to apportion analysis variables. The Data source section of each country or region page provides settlement points information, when available.
Data sources and reliability
Data enrichment is available in over 170 countries and regions. Data sources, enrichment variables, and data quality vary by country and region.
Some countries/regions, such as Australia, Canada, Japan, the Netherlands, and the United States, include variables that describe, in detail, the characteristics and consumer behaviors of their citizens. Other countries and regions have fewer variables based on coarser census or postal code geographies. Consequently, the reliability of data enrichment can vary by country or region and sometimes by location within a country or region.
When raster-based settlement points are used in an enrichment operation, the metadata returned includes a reliability statistic for each country or region. The ratings for reliability range from 1.0 to 5.0, where 1.0 is the most reliable. All other countries/regions that use different settlement point methods have scores of -1.
