Full Description

AidData’s Core Research Release Version 3.1 provides a few fixes to the AidData Core Research Release 3.0. No new data has been added, but the following changes have been made:

  • This version of AidData's Core Research Release eliminates activity codes for 363,265 projects. This action was taken in response to an internal review, which revealed that these codes were incorrectly applied during an internal data migration exercise. This version also reapplies a corrected set of activity codes to 71,176 (of the 363,265) projects that were identified as having incorrect activity codes.
  • We have added a column providing the commitment amount of the projects in current USD, which will allow users to do their own deflation calculations if they wish.
  • We have removed a duplicate “finance_t” column in the dataset.

As with the 3.0 release, this dataset represents the most comprehensive project-level data tracking international development finance. The base of the Research Release is all core data exported from the AidData Portal at The Research Release serves as 1) a time-stamped version of AidData’s core data, which allows users and researchers to replicate their research results, and 2) a version of the data that is provided in a flat-table structure, allowing for users and researchers to analyze annual commitments more easily. This dataset was developed by AidData with the support of AidData’s core funders, including the Hewlett Foundation.
