The last population estimate before Hurricane Katrina was 454,865, as of July 1, 2005. A population analysis released in August 2007 estimated the population to be 273,000, 60% of the pre-Katrina population and an increase of about 50,000 since July 2006. A September 2007 report by The Greater New Orleans Community Data Center, which tracks population based on U.S. Postal Service figures, found that in August 2007, just over 137,000 households received mail. That compares with about 198,000 households in July 2005, representing about 70% of pre-Katrina population. More recently, the Census Bureau revised upward its 2008 population estimate for the city, to 336,644 inhabitants. In 2010, estimates showed that neighborhoods that did not flood were near or even greater than 100% of their pre-Katrina populations.
