During the 1920s, did American women want large families?
In the United States in the 1920s, women were starting to want smaller families. This is not true for all women, but it is true on average.
The 1920s were a time when women were becoming freer in American society. They were starting to work more outside the home. They were starting to be more interested in having fun. Because of these things, they started to want to have smaller families.
One famous thing that happened because of this is that Margaret Sanger became famous. She was an early leader who wanted to make birth control available to women. She was popular because women wanted birth control so that they could have smaller families.
I agree with the above answer. When it comes to the 1920's, though, society at that time was a little schizophrenic. While the promiscuous attitudes of young women "Flappers" and others revealed a more liberated view of life, most of the country was still socially conservative.
Margaret Sanger was an activist for birth control rights, but she also was arrested numerous times, and to distribute birth control or even information about it was often in violation of local and state laws. Attitudes by mainstream America towards her efforts and towards large families remained largely unchanged in the 1920's.
