It is important that you cite the date of the current edition (1945-2008) because the data on the web will change with the next annual update.

Yes, “no data are available” means there wasn't any foreign aid given to that country for that year/program. Also see question 12, “What is the difference between “.” and “0.0”?”

No. Foreign assistance data collection and reporting takes time. The Greenbook is updated annually and there is a two-year lag between the present year and the most recent data reported. In other words, in 2010, the most recent data available is for 2008. The 2009 data must be vetted, approved and ready for release in the fall of 2010.

Countries are organized alphabetically into eight geographic regions, plus Canada: Middle East and North Africa, Sub-Saharan Africa, Latin America and Caribbean, Asia, Oceania, Eurasia, Eastern Europe, Western Europe, and finally Canada. If a geographic region is selected, a total for that region will be retrieved.

Historical dollar amounts are the actual amounts. Constant dollar amounts are inflation-adjusted values. See "About Constant-Dollar Data" for more technical information on the inflation-adjusted amounts. The constant dollar series allows you to evaluate, on a comparable basis, loans and obligations that occurred in different time periods.

The Greenbook is a report on total U.S. foreign assistance, including military assistance, to every country in the world. It reports on fiscal year obligations and is produced annually for Congress.

United States Official Development Assistance (ODA), as reported to the OECD/DAC is a subset of total U.S. foreign assistance. Most notably, it does not include military assistance and is only reported for ODA-eligible countries. ODA is reported on a calendar year basis and tracks both obligations (the commitment/promise of funds) and disbursements (the actual delivery of funds).

Other difference between the figures presented in the Greenbook and those reported to the OECD/DAC do exist. They include the reporting of debt forgiveness and the inclusion of domestic refugee costs, both of which are reported to the OECD/DAC and not included in the Greenbook figures.

Though ODA as reported to the OECD/DAC is a subset of total U.S. foreign assistance, we recommend using ODA when comparing U.S. foreign assistance against other OECD members' assistance.

Note that the years appearing in the drop-down list will be the years for which there was foreign assistance from the U.S.

1976TQ contains funding data for a transitional quarter. The transitional quarter was an accounting device to accommodate the 1976 change of the U.S. Government fiscal year from July 1–June 30, to October 1–September 30.

Since its inception, responsibility for compiling the U.S. Overseas Loans and Grants report (the Greenbook) has passed among several organizations. Beginning with the 1999 edition, the Greenbook has been produced by DevTech Systems, Inc. for USAID.

A review of data for 1946–1998 by the DevTech Systems, Inc.'s staff revealed the following issues:

• Historical data had not been adequately revised as new information became available.
• New appropriations were not consistently captured as the number of U.S. government agencies undertaking foreign assistance activities increased.
• Historical data were not recorded by appropriations or accounts as needed to be consistent with today's reporting convention.

In addition, the timeliness of reporting varies by agency and program. For example, Food Aid and Military Assistance have traditionally had the greatest lag in reporting and, therefore, are often subject to revision.

As with most time series datasets, historical revisions are necessary to improve the accuracy and consistency of the dataset. Users are alerted to significant revisions in prior year data in the last section of the "Reporting Concepts" section of the Greenbook.

No, the Greenbook does not provide data by the type of program funded (e.g., irrigation, democracy promotion, literacy, HIV/AIDS). The Greenbook tracks foreign assistance by legislated funding accounts and a funding account may be used for many types of programs.

The only authoritative source for U.S. Government assistance by purpose, is the OECD/DAC Development Database on Aid from DAC Members. This database tracks "Official Development Assistance" by donor country, recipient country and sector/purpose of assistance. Please see the FAQ "What is the difference between the data on this site (Greenbook data) and assistance data presented by the OECD/DAC?" for more information.
