The results regarding evolution of Gross Domestic Product (GDP) are presented in this review paper. One of the major aspects of analysis of GDP is the correlation between GDP and Final Consumption Expenditure (F.C.E), which is an important macroeconomic indicator. The evolution of GDP is highly related with the evolution of final consumption. For analyzing the correlation, linear regression model has been used as it is one of the most suitable instruments for such approach. The regression model in this review paper uses FCE as the independent variable and GDP as the dependent variable.
