Spatial Equity Data Tool

Measure Disparities in Your Data

Last updated February 27, 2024

Are libraries evenly located across the country? Do all residents in your state—regardless of race or income—have equitable access to polling places? Does your dataset accurately reflect your county’s or city’s population?

This tool can help government agencies, policymakers, and community advocates easily answer such questions by assessing demographic and spatial disparities in their data.

Choose a geography below to get started. Then check out our sample datasets or upload your own data.

Instructions

Your CSV file must have unique column headers.
Two columns must correspond to longitude and latitude.
Your file size must not exceed 2 GB
Note: The national tool can only analyze data from the entire US (50 states plus the District of Columbia). If your file contains data for only a subset of the US (e.g., a few states) it will be compared against the entire US, so results may not be accurate. Instead, you may want to choose a different geography from the home page to analyze the state, county, or city that appears most frequently in your data.
Note: The state tool can only analyze data for US states (the 50 states plus the District of Columbia) and for one state at a time.
  • If your file contains data from multiple states, only the state that appears most frequently in the data will be analyzed.
  • If your file contains data for a subset of the state (e.g., a few counties or a few cities), it will be compared against the entire state, so results may not be accurate. Instead, you may want to choose a different geography from the home page to analyze the county or city that appears most frequently in your data.
Note: The county tool can only analyze data for US counties (within the 50 states and the District of Columbia) and for one county at a time. If your file contains data from multiple counties, only the county that appears most frequently in the data will be analyzed.
Note: The city tool can only analyze data for US cities with populations above 50,000 and for one city at a time. If your file contains data from multiple cities, only the city that appears most frequently in the data will be analyzed.

Advanced options: Filter data

Choose a column to filter by and the tool will detect which values—text, numbers, or dates—are in that column. The filters will allow you to focus on data you want to use and hide data you don’t. Columns with both text and numbers will be treated as text fields.

For help, see our FAQ.

Weight data

Advanced options: Weight data

You can weight the rows by a numeric column in your data when calculating representativeness. For example, in a dataset of library locations, if you choose “sq_ft” as your weight column, higher–square footage libraries will be given more weight in assessing representativeness.
