Question

developed (those with higher income per person) countries tend to have low total fertility rates which results in a lower birth rate. what is one cause of this?
easier access to birth control
high death rates in factories
lack of education for women
greater amounts of good food

Explanation:

Developed countries have widespread access to contraception, which allows individuals to plan and limit the number of children they have, directly lowering total fertility and birth rates. The other options are incorrect: high factory death rates are not a feature of modern developed nations, lack of women's education is associated with higher fertility, and access to good food does not reduce birth rates.

Answer:

easier access to birth control
