Answer:
Rich countries typically have a low total fertility rate, a low infant mortality rate, and a higher number of years of education than poor countries.
Explanation:
Developed countries are known to have a significantly lower fertility rate. This is usually correlated with greater education, urbanization, wealth, and other factors.
Inequality in income is a crucial factor in determining infant mortality rates. Thus countries with less income inequality - rich countries - experience lower mortality of infants. In essence, one of the major determinant of infant mortality is poverty.
