Quarterly Estimates of Output-Based GDP

The Singapore Department of Statistics (DOS) compiles estimates of GDP using all three approaches, viz. output, expenditure, and income. Each of the three approaches views GDP from a different perspective. Taken together, these three approaches provide a more complete picture of an economy than any single approach could.

Annual real and nominal GDP estimates using the output approach are available from 1960, while the quarterly estimates are available from 1975. The quarterly estimates are important short-term indicators of Singapore’s economic performance.

The data sources and methodology adopted by DOS for the compilation of timely, quarterly estimates of output-based GDP are provided in DOS's Information Paper, titled "Quarterly Estimates of Output-Based GDP"   (6.1 MB).
