People living in urban areas:

Rates tend to be lower in developed countries, where raising children is much more costly because children don't enter the labor force until their late teens or early twenties.


TFRs tend to be low when women have access to education and paid employment outside the home.

In developing countries, women with no education generally have two more children than women with a secondary school education.
