New Orleans has had a complex history of population growth and decline. The city has experienced both periods of growth and decline.
After the Louisiana Purchase in 1803, New Orleans experienced a period of rapid population growth. The city's population increased from about 10,000 in 1803 to more than 100,000 by 1860, making it one of the largest cities in the United States at the time.
However, the city's population began to decline in the early 20th century. The population dropped from around 627,000 in 1910 to about 437,000 in 1960, due to factors such as economic decline, suburbanization, and the effects of World War II.
In the recent years, New Orleans has seen a rebound in population growth. After the devastating Hurricane Katrina in 2005, the population dropped significantly, but it has been steadily increasing since then. According to the U.S. Census Bureau, New Orleans' population was estimated to be 391,006 in 2020, this is an increase of 3.2% from the 2010 census.
