Population growth is mainly driven by the decline in fertility rates, which has allowed more women to pursue education and careers. this has led to better access to healthcare, improved education, and more economic opportunities. this has resulted in more people having access to better quality of life and a longer life expectancy, which in turn has led to a growing population. additionally, advances in technology and transportation have allowed for easier movement of people, leading to an increase in migration and population growth.
