AidData has developed an open source data collection methodology, called Tracking Underreported Financial Flows (TUFF), to collect project-level data from suppliers of official finance who do not participate in global reporting systems. This codebook outlines version 1.2 of the TUFF procedures that have been developed, tested, refined, and implemented by AidData researchers and affiliated faculty at the College of William & Mary and Brigham Young University. 

We first employed these methods to achieve a specific objective: documenting the "known universe" of Chinese official finance projects in Africa from 2000 to 2011. Since the launch of that pilot dataset (version 1.0), we have applied the data collection procedures outlined in this document to track project-level development activities sponsored by four Gulf Cooperation Council donors and Venezuela, and created an updated dataset of Chinese official finance in Africa (version 1.1). These data collection exercises have demonstrated that TUFF can be successfully applied to other official finance suppliers.

Since the release of the 1.1 version of the TUFF methodology in January 2014, AidData has continued to refine the methodology by identifying new sources of primary data and identifying systematic sources of bias that can be corrected or minimized. This 1.2 version of the methodology reflects the following changes: 

  • Expanded universe of information repositories scraped by TUFF, including aid information management systems, Economic and Commercial Counselor websites, and more academic sources.
  • Improved data standardization by merging project fields with the potential to be coded non-systematically (specific to “Chinese Official Finance to Africa” project).
  • Developed project templates for recurring Chinese aid activities.
  • Created automated coding rules related to specific funding agencies and project types, and developed methods for identifying projects which violated these coding rules.
