most of the past century, there has been a negative relationship between economic development and human fertility.They found that the fertility rates of countries are linked to their Human Development Index (HDI), which evaluates life expectancy, average income, and education levels, and that in some countries, particularly those with an HDI of over 0.9, fertility rates have begun to increase and, in some cases, are approaching two children per woman.While there are some exceptions, such as Japan, it appears that higher levels of wealth and education can ultimately lead to a desire for more children.

most of the past century, there has been a negative relationship between economic development and human fertility. This means that as a country's wealth increases, the average number of children born per woman decreases. While women in the poorest countries may have up to eight children, some European countries, like Italy, have experienced a decrease in the rate to as low as 1.3 children per woman, which is below the replacement level. This low fertility rate has two likely negative consequences: the population will fall in the long-term, and a growing number of old people will have to be supported by a shrinking number of young.
However, a recent study by Pennsylvania University researchers suggests that this trend may be changing.
