Download data

The datasets and resources listed below are all updated annually and free to download and/or use. They are designed to be accessible not only to researchers, but also to policymakers, parents, journalists, and other stakeholders. Analyses of measures in both datasets can also be found in our annual reports and research briefs.

State Indicators Database

The SID is a dataset of roughly 125 state-by-state school funding measures for each state between 1993 and 2018 (not all variables are available in every year). It includes variables for assessing, between and within states (by district poverty level): the adequacy of spending levels; the fairness of state and local spending and revenue (whether poorer districts receive more resources); state “fiscal effort” (how much of states’ economic capacity is devoted to education); resource allocation (e.g., teacher pays, staffing ratios); and more.

  2. Download the full SID dataset in Excel format
  3. Download the full SID dataset in Stata format
  4. Use our online data visualization tools: view one-page state profiles or visualize key SID measures (effort, adequacy, progressivity, and teacher pay competitiveness) 

District Cost Database

The DCD is a district-level dataset that allows users to assessing the adequacy of spending in roughly 12,000 public school districts. For each district, users can assess spending adequacy by comparing: 1) actual per-pupil spending; and 2) the estimated per-pupil spending level required for that district to achieve national average test scores. (Note that the same basic measures, but for entire states, are included in our state database, above.) The DCD also includes a small group of variables measuring district characteristics, such as testing outcomes, enrollment, and Census poverty rates, that users can compare with adequacy. The database currently includes data for 2018 only (the 2017-18 school year).

  4. Use our DCD online visualization tool: select a district to display a profile of spending adequacy and other measures in that district 

The data sources for all of our measures are listed in the user’s guides. We recommend that users review this documentation and data use agreements contained therein.
