single having children

A downward fertility trend is occurring on the global front: women aren’t having enough children. Recent statistics place the Italian fertility rate at just 1.3, whereas the replacement rate is usually considered to be 2.1 children per couple.
Furthermore, 50% of Japanese women born in the 1970s are childless and many European countries face a 20% rate of childlessness in women in their 40s.

Some people may argue that the world population is out of control and that lower fertility is a good thing.
