The aim of this study was to quantitatively combine the results of research conducted on the impact of population growth on economic growth, using meta-analysis method and comprehensive meta-analysis software (CMA2, STATA15) and searching in different databases among 143 articles, 48 ​​dissertations, and 32 selected articles. Finally, 18 studies were selected and reviewed based on six meta-analysis criteria.

Population growth has a negative effect on economic growth with an effect size of -0.38. Also, the age structure of the population with the effect size equal to 0.91 positive effect, the type of model used with the effect size of 2.27 in the self-explanatory vector pattern and 3.16 in the data panel pattern, the data type with the effect size (2.18, 3.13, and 0.40 respectively) in data (cross-sectional series, integrated data, and time series data) and skill combination with an effect size of 0.63 had a positive effect on economic growth.

According to the funnel diagram, the effect size of the studies did not have a diffusion bias. The magnitude of the effect on males is greater than females. Therefore, it can be said that men have a greater impact on economic growth. The effect of increasing education and skills were found to be significant.
