That's because condoms and other ways of birth control weren't very common yet before World War 2. In third world countries, most people still don't have the money and possibilities to buy these things.

It's not just money. There's also that pope guy trying to brainwash Africa into hating contraception.

Sure, it isn't just money, but money is the most important factor. Even in countries with a constitution based on religion, contraconception is now (partially) legal.
