Was the baby boom in the 1920s?

No, the baby boom did not occur in the 1920s; it took place after World War II, roughly between 1946 and 1964. The 1920s, known as the "Roaring Twenties," were characterized by economic prosperity and cultural change, but birth rates did not see a significant increase during that decade. The post-war baby boom was driven by factors such as returning soldiers, economic stability, and societal norms favoring larger families.
