Religion and birth control are both a question of indoctrination by the state. The Soviet Union and its satellite states managed to reduce religious belief fairly effectively, in the Czech Republic ~70% are atheist / non-believers, East Germany has similar numbers. They provided free access to birth control, abortions and infant child care. Of course none of this would be possible in most of the world, religious belief is too entrenched and there are no strong ideologies left that are prepared to fight it.
