We use a variety of data sources to tailor our analysis to the location and to make our estimates as accurate as possible. However, sometimes data is unavailable, either because it has not been collected, or because it is not shared publicly. We encourage government agencies and other organizations to share their de-identified data online and researchers to prioritize the following gaps in the data.

Detailed Graduation Rates by Income and Race/Ethnicity – In order to model the impact of the intervention on health equity it is important to have data for the subgroups over which equity is estimated. In the intervention, equity was measured across income and race/ethnicity. Unfortunately, imputation was necessary to determine graduation rates by the appropriate subgroups. Furthermore, income is only classified by a binary classifier for students above or below a threshold. More detailed income classification would allow for more detailed equity impacts.
