Since Hurricane Katrina struck New Orleans ten years ago, data has played a central role in tracking how the city has transformed.

The storm greatly changed the physical and demographic makeup of New Orleans. Monitoring these changes is important, since the needs of the city and it’s people are much different today. “After any disaster, applicable data is wiped away—all information becomes uncertain,” says Allison Plyer of The Data Center, a data collection and analysis group that serves Southeast Louisiana.
