The first step in measuring an economy is establishing a profile of the GDP. Pakistan has only rebased twice, in 1969 to the 1960 base year, and in 1988 to the 1980 base year. In 1997, the Nawaz Sharif government began the technocratic process of rebasing. This process, which involved IMF representatives, was completed this year, and the economy was rebased to 1999 data.
