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. The Great Depression and post World War II years saw a slowing of growth leading into an eventual decline. The mid to late century were hard times, as the Bronx declined 1950–85 from a predominantly moderate-income to a predominantly lower-income area with high rates of violent crime and poverty. The Bronx has experienced an economic and developmental resurgence starting in the late 1980s that continues into today.
