This is the most important factor that resulted in population growth. Improved sanitation, better housing, advances in medicine, and more nutritious foods all worked to reduce the rate at which people died from diseases and other natural causes.
2. Improvements in agricultural production:
New farming technologies, such as fertilizers, pesticides, and tractors, allowed farmers to produce more food on less land. This meant that more people could be supported by the available food supply, which in turn led to population growth.
3. Increased urbanization:**
As more people moved from rural areas to cities, they had better access to healthcare, education, and other resources that helped to improve their quality of life. This resulted in a decline in the death rate and an increase in the birth rate, both of which contributed to population growth.
