Education Data Portal - Summary Endpoints

These experimental summary endpoints extend the functionality of the Urban Institute's Education Data Portal application programming interface (API). Where the original API allows researchers to easily access millions of raw records for further analysis, the summary endpoints provide rapid, customized access to aggregated statistics in seconds for policymakers, journalists, and community groups.

Please note that these summary endpoints are a initial proof of concept, and only six tables are currently available at this time. We hope to do a more complete rollout in a future release. We appreciate all feedback, which can either be filed as an issue in this GitHub repository or sent to:

For additional background, see our Data@Urban blog post from January 2019: Democratizing Big Data to Support Proactive Policymaking.

This work was supported in part by the Amazon Web Services (AWS) Imagine Grant Program.

User Guide


The general form of an API call is as follows:{section}/{source}/{topic}/summaries?var={var}&stat={stat}&by={by}


  • {topic} is one of college-university, school-districts, or schools.
  • {source} is the data source, i.e. ccd, crdc, ipeds, edfacts, saipe, or scorecard.
  • {endpoint} is the endpoint, i.e. enrollment, ap-exams, etc.
  • {var} is the variable to be summarized. Must be a numeric, non-filter variable.
  • {stat} is the statistic to be calculated. Valid options are:
    • sum
    • count
    • avg
    • min
    • max
    • variance
    • stddev
    • median (note that this is mapped as an approx_percentile(var, 0.50) query)
  • {by} is the variable(s) to group results by. Multiple variables can be given as a comma separated string, i.e. by=fips,race. All queries are also automatically grouped by year by default.

Example Use

A simple call will look like:

This will return the sum of enrollment by fips code and year for the schools/ccd/enrollment endpoint.

Where applicable, tables have been pre-joined against their associated directory file, providing additional options for by and filter arguments. For example, we can call:

even though school_level is only available in the schools/ccd/directory endpoint and not the schools/ccd/enrollment endpoint.

Adding Filters

Additional filters can be added to the API call as additional query string parameters in the form {filter}={value}. Multiple values can be given as a comma separated string. For example:,2

will return the sum of enrollment by sex and year for the schools/ccd/enrollment endpoint where fips is 6 and race is either 1 or 2.

Additional Help

See the full documentation for the Education Data Portal for additional information on the project.

In particular, the topic specific documentation may be useful when constructing a query:

Available Endpoints

The endpoints currently available are:

  • schools/ccd/enrollment
  • schools/crdc/ap-exams
  • schools/crdc/enrollment
  • schools/crdc/harassment-or-bullying/allegations
  • schools/crdc/restraint-and-seclusion/instances
  • college-university/ipeds/completions-cip-6
    • Note: this endpoint will only return data when award_level is specified as a by variable.

Data for additional endpoints is currently being tested. This list will be updated as new sources are added.
