According to the main scenario of the projections, population will reach 107.7 million in 2069, and from this point, it will decrease to 107.1 million in 2080. TurkStat population projections method covers the dimensions which is based on the institution’s long term experience and data, the principles of the discipline of demography e, and international data compiled. My aim in this econometric study is to investigate the representation of the main scenario projections and the results of past censuses with five and six parameter Gompertz population growth model which was developed during this study and also sinusoidal function applications for the residuals. In addition, I also applied Verhulst five and six parameter functions and reached positive statistical and linearity test results made with all functions. The results of the econometric study confirmed that the main scenario projections of the Statistical Institute are valid and realistic.}, number={2}, publisher={TÜİK}
