During World War 1 and 2 in France, population growth was low due to high death rates and low birth rates. Men were conscripted into the army, many died in battle, and reproduction was halted. Death rates were high in villages and towns targeted during the wars due to bombings and injuries. In England and Wales, stage 2 of the demographic transition saw vaccination and public health acts lower death rates through reduced disease spread. Banning child labor and poor laws increased birth rates. Stage 3 brought deliberate family restriction, and world wars lowered birth rates while improving health care lowered death rates.
