The march through the streets of the Lower East Side and Chinatown was dubbed 'A Call to Action, A Day of Unity,' and participants hoped to draw attention to the plight of the working class residents who have been displaced by gentrification.

"This country allowed Katrina to happen, this country allowed the disaster to occur. And they allowed people to be displaced,” said marcher Beverly Corbin.

"We not only march for the people of New Orleans, we march for those in Chinatown. We march for those in the lower east side, we march for those who have been priced out in Harlem, we march for those whose homes have been bulldozed in New Delhi," said another.

Criticism of the government, both federal and local, was a common theme Friday.

As the south prepared for Hurricane Gustav, Katrina survivor Jay Arena, a recent transplant to New York, had his friends back in New Orleans in his thoughts.

“It's very difficult to be here while they're facing this possibly devastating storm," said Arena, "and on top of that, the trauma that they've gone through because of a lack of adequate government response.”

"It’s important to remember it, especially since a lot of the people who survived are still unable to return to their homes… those that have them. And those that don't are unable to go back to New Orleans at all, especially is they are people of color," said another protester.

In Washington Square Park, the Judson Memorial Church hosted a fundraiser for those displaced by the storm, featuring work by Gulf Coast artists and photography that showed vividly that much work remains in the rebuilding effort, three years after Hurricane Katrina.

"We saw an opportunity to bring our forces together and really support the culture. What we have in New Orleans isn't found anywhere else in the world,” said Kasey Lockwood of NOLA Preservation Society.

The money raised by the group was intended to send volunteers to help rebuild the Gulf Coast. This year, they sent 30 volunteers and next year they want to sent 100.

Meanwhile, a new report released Friday found that nearly half of the 1,000 Louisiana residents who died in Hurricane Katrina were aged 75 or older.

Researchers from the Center For Disease Control and the Louisiana Office of Public Health said many elderly residents were ill-prepared for the aftermath of the storm or too frail to leave their homes.

The number one cause of death among all victims was drowning, and the number of deaths were fairly evenly divided among men and women and blacks and whites.
