Correlation Between GDP Per Capita and Total Fertility Rate in Japan (1990-2010)

This research investigates the extent to which economic growth, measured by GDP per capita, correlates with the total fertility rate in Japan between 1990 and 2010.

The methodology utilizes secondary data from the World Bank and Japan's Ministry of Health, Labour and Welfare, applying Pearson Correlation Coefficient (r) and R² analysis to quantify the relationship. The findings reveal a weak negative correlation (r = -0.35), concluding that economic growth is a contributing but not sole factor in fertility decline.

The exemplar is distinguished by its rigorous statistical approach, integration of the demographic transition theory, and a critical evaluation of regional disparities and latent economic effects.
