The growth rate of population is determined by birth and death rates.
Birth rate refers to the number of live births per 1,000 people in a given population over a certain period of time. Death rate, on the other hand, refers to the number of deaths per 1,000 people in a given population over the same period of time. These two rates together determine the growth rate of a population.
If the birth rate is higher than the death rate, then the population will grow. If the death rate is higher than the birth rate, then the population will decline. If the birth and death rates are roughly equal, then the population will remain stable.
Various factors can influence birth and death rates, including access to healthcare, education, economic development, and cultural norms. For example, in areas where access to healthcare and education is limited, birth rates may be higher due to a lack of family planning resources and limited knowledge about contraception. In areas where there are high levels of poverty and limited economic opportunities, death rates may be higher due to malnutrition, disease, and other factors.
Improvements in agriculture and technological know-how can indirectly affect birth and death rates by improving living standards, increasing access to healthcare and education, and creating economic opportunities. However, these factors do not directly determine population growth rate; birth and death rates are the key drivers of population growth or decline.
