The central statistical office, or CSO, is responsible for compiling data for calculating GDP. It aggregates the GDP data by coordinating with several federal and state-run agencies. Once the data collection process is completed, the task of calculating the GDP begins. There are two methods to arrive at the GDP number:,handball-world-cup-2021-online-stream
- Known as GDP at factor cost, the first method looks at the economic activity
- The second method is the expenditure-based method (at market prices).
- Further, the nominal GDP is calculated using the current market price, and real GDP is arrived after adjusting inflation.
Among the four sets of GDP numbers, GDP at factor cost is the most commonly used figure and reported in the media. While the GDP at factor cost reveals which industry sector is doing well, the expenditure-based GDP is indicative of the status of different areas of the economy; how the trade is doing or whether investments are on the decline.
For the calculation of GDP at factor cost, data is taken from eight sectors, namely agriculture; mining and quarrying; manufacturing; forestry and fishing; electricity and gas supply; construction, trade, hotel, transport and communication; financing, real estate and insurance; and business services and community, social and public services. For the calculation of expenditure-based GDP, all the spending incurred on final goods and services are added that include consumer spending, government spending, business investment spending, and net exports.
The government releases quarterly GDP numbers every two months, and the final numbers for the whole year are issued on May 31.
