Data sources
Primary data were collected through three institutional survey rounds in 1997-1999 (jointly by IFPRI and ISNAR), 2007-2009, and 2013-2014 (under ASTI). These data were combined with a few secondary sources for the pre-1996 period.

Estimation procedures
- For a number of agencies, research staff and expenditure data were missing for certain years. These have been interpolated or in a few cases extrapolated.
- Expenditures for the higher-education agencies are estimates based on the average expenditures per researcher for the government agencies.
