Development finance data are collected using a converged reporting system whereby bilateral and multilateral providers of development co-operation use a single file format (Creditor Reporting System – CRS) to report at item level on all flows of resources to developing countries. Item-level reporting is validated against key aggregates also reported by donors and then serves as the basis for producing various other aggregate statistics.

Below you will find the questionnaires used to report data as well as the reporting instructions and supporting documents needed for their completion: all data are reported against a single set of Converged Statistical Reporting Directives and supporting addenda.


  • Advance DAC questionnaire (xls, March 2019)
    used to collect preliminary aggregate ODA data which is then published each April for the preceding year.
  • Converged questionnaire (xlsm, May 2020) 
    used to collect detailed, item-level CRS data, and aggregate data for validation, published each December for the preceding year. In this year’s edition the whole section on TOSSD reporting was added. 

Most data reporters now report in the converged format.

However, during a transition period, those reporters not yet doing so provide CRS item-level data and DAC aggregates separately:

Reporting Directives and Addenda

The Converged Statistical Reporting Directives are essentially the rule book for how to report statistics on aid and other resource flows.

  • Addendum 1 contains supporting information on the classification of flows such as the List of ODA recipients, the List of ODA-eligible international organisations and various code lists which all require regular updates.
  • Addendum 2 contains detailed definitions (grant element, policy markers) and the comprehensive text of DAC Recommendations, which do not require frequent updates.
  •  Addendum 3 presents the reporting methods for private sector instruments and the technical details for the reporting forms.

The Data Cycle

Data cycle FSD

We collect development finance statistics from DAC member countries, non-DAC countries, multilateral organisations and private donors.

The DAC and CRS online databases are updated every quarter (April, June, September, December).


Latest update: The DAC online databases were updated in April 2019. This update includes the preliminary figures on ODA in 2018.
