Meta information:

Description:
A chain index refers to a method of constructing a time series by linking indices calculated with the previous period as the base. In the estimation of GDP at constant prices, the chain index approach links period-to-period growth indices to measure real economic growth. A key feature of this method is that the base year is updated annually.
Methodology name
Methodology for estimating GDP chain-linking method (Order A/129 of Chairperson of NSO on December on 08, 2025)
About table
Calculation method
In estimating GDP at constant prices, three calculation methods are applied: the deflation method, the revaluation of quantities, and the extrapolation method. When estimating GDP at constant prices using the chain index approach, the deflation method is required. However, for some industries, appropriate price indices are not available, or output is expressed in physical quantities, making it impossible to apply the deflation method directly.
