The Ugandan Bureau of Statistics (UBOS) is responsible for producing national accounts statistics (NAS). Estimates of gross domestic product (GDP) by economic activity and expenditure share are compiled on an annual basis and disseminated via the quarterly Key Economic Indicators and annual Statistical Abstract publications. Summary estimates are released in the government budget papers and via the UBOS website. UBOS commenced disseminating improved quarterly constant price GDP estimates through its website in October 2011. The GDP estimates are broadly consistent with the System of National Accounts 1993 standards.
