I'm glad the Japanese government is doing a better job of clean up than the U.S. did with Katrina. I'm still worried about the fact that Japan has not expanded the evacuation zone around the reactors.
Here is a study about NO population in three periods, the last being post Katrina.

While the Army Corps of Engineers and the employees of Jefferson and Orleans parishes drained the flooded city, the demand for laborers to clean up the soggy mess surged. Foreign-born Hispanic migrants were the first to respond to that demand, just as they have followed the construction boom throughout the New South. That is not surprising, since workers born in Mexico and Central America make up about 21 percent of the U.S. construction labor force. Although many New Orleanians were unprepared to see those unfamiliar faces and hear strange languages in their nearly empty city, the newcomer Latino migrants were the rapid-response labor force that was necessary to reconstruct New Orleans.<15>
Nevertheless, the migrants received a mixed reception. The federal government welcomed the labor force by suspending the Davis-Bacon Act mandating that federal contractors pay prevailing wages and by waiving sanctions against employers who hired undocumented workers, thereby letting market forces reign.<16> New Orleanians able to return home were pleased to find workers to clean out their moldy belongings, gut houses and other buildings, repair and replace roofs, and paint over the cryptic markings left on their doors by search-and-rescue crews. Displaced New Orleanians in the newly formed diaspora, many of them former renters, resented the speedy arrival of Hispanic workers while they waited to find out when they could return home or receive assistance or whether the city would devise a plan for rebuilding the most devastated neighborhoods. Such New Orleanians, many of them working-class blacks, understood that they would not be part of New Orleans’s reconstruction labor force, at least not unless they accepted the conditions—dangerous work without adequate protection, lack of housing, low wages—that migrants tolerated. New Orleans’s history with race and class shaped the experience of the flood and evacuation. Low-income black neighborhoods in low-lying areas suffered a disproportionate share of the floodwater, while wealthier, whiter neighborhoods on higher land stayed dry. Those disadvantages accumulated more rapidly for those who were already disadvantaged—mostly low-income blacks—creating more obstacles to their return.<17>

The repopulation of the city has disproportionately drawn those with more resources. Resources in this case are defined by what you had before the storm—a home, job, savings, and insurance—and whether it survived. The return rate has been highest among the 34 percent of the city’s households deemed to have minor or no damage, while a much smaller percentage of the population from the 66 percent of households that experienced serious and severe damage returned. Those returning to homes in the damaged areas were those with the financial resources to rebuild. The largest federal source of rebuilding aid to low-income homeowners, the Road Home program, proved too little, too late for most. On the second anniversary of Katrina, the city of New Orleans is only 67.6 percent of its pre-Katrina size, with little promise of regaining its pre-storm numbers.<18>
The demographic composition of the city is difficult to pin down given the state of flux of the population. It is widely held that the city is “older, whiter, and more affluent” than before Katrina, since black and poor residents were more likely to have lived in devastated areas and in ruined rental property. Many thought residents with children were less likely to return because schools were so slow to open. Statistics produced since Katrina are subject to large margins of error, but they confirm those impressions. By summer 2006 New Orleans had gone from having a population that was two-thirds black and less than a third white, with small Asian and Hispanic minorities, to having nearly equal proportions of blacks and whites (47 percent and 42.7 percent respectively) and somewhat larger Asian (3.5 percent) and particularly Hispanic (9.6 percent) minorities. At the time of that survey, the city was less than half its pre-Katrina size, and a larger proportion of whites had returned than blacks. Furthermore, the proportion of Hispanics had grown, no doubt as a result of the reconstruction labor force. (See figure 4.)<19>
