New Orleans Loses a Third
Much of that loss is due to the devastation following Hurricane Katrina in 2005.
"Census workers counted 343,829 residents in New Orleans last year, down from 485,000 in 2000, or a 29% drop, according to the data. The count was slightly lower than previous estimates of 355,000.
The city has struggled to repopulate since Hurricane Katrina and a breach of federal levees flooded 80% of the city in 2005, scattering much of its citizenry. Just before the storm, there were about 455,000 people living in New Orleans, according to Census figures."
