You might look into the great flu epidemic of 1919-20--it was actually part of of a worldwide pandemic and claimed its share of American lives.
Another was World War II--any war brings fatalities, so there were numbers of men and women who were unable to reproduce--HOWEVER--after the war, the birth rate was phenomenal. 1946-47 through the early '60's were the years of the so-called Baby Boom, when an only child was a relative rarity. My own mother had five, and most of the kids I started school with had at least one older and often on or two younger siblings as well.

the baby boom.... it was 1946-1964 (I believe) when all the war veterans from WWII came home, married and started families. The Industrial Revolution ended around 1920, but I'm sure that also changed the popuation. The Great Depression (1932).... thats all I can think of now, but those events did cause changes in the US popuation.

dust bowl in the 1930s was a huge contributing factor to the "great depression" not only were huge numbers of people out of work and jobs, there was no way to feed the huge masses that went looking for same, this in and of its own merits was a political contributing factor of wwII the war was a way to ramp up the industrial base of the us, providing income and wealth for the people thats still on a roll.
