Approximately what percentage of the total population lived in the suburbs in 1910 How long did it take?

In 1910, approximately 10% of the total U.S. population lived in suburbs. The suburban population began to grow significantly in the early 20th century, particularly after World War II, when factors such as the rise of the automobile and increased housing developments contributed to suburban expansion. It took several decades for suburban living to become a prominent trend, with substantial growth occurring from the 1940s through the 1960s.
