I want to know the answer to the following question:
When was the Bronx's boom period?
All the background I'm provided with is that "The history of the Bronx during the 20th century may be divided into four periods: a boom period during 1900–29, with a population growth by a factor of six from 200,000 in 1900 to 1.3 million in 1930.". Is that enough to answer the question?
