Critical data, challenging circumstances:Lessons from implementing the 2006 Louisiana Health and Population Survey

Introduction: The 2005 hurricane season drastically altered the population size and demographics in Louisiana. Timely, accurate population estimates were needed to guide decision-makers in placement of public services and allocation of disaster recovery funds. As a result, the Louisiana Health and Population Survey was developed to rapidly compile critical health and demographic information on households in 18 hurricane affected parishes from June-December 2006.

Research Design: The survey methodology for the 2006 Louisiana Health and Population Survey was developed by the U.S. Census Bureau, the U.S. Centers for Disease Control and Prevention (CDC) and the Louisiana Public Health Institute (LPHI). The survey relied on a two-stage cluster sample design. The survey employed these standard survey methods with modifications made for applicability in the post-disaster setting.

Results: Results from the survey provided parish level health and population estimates in 18 parishes across southern Louisiana. Additionally, survey managers faced unique and challenging conditions caused by the magnitude of the disaster—habitability determinations, bulldozing of residences, and movement of FEMA trailers were among the challenges faced. Further analysis on survey management techniques revealed the need for alternative methods and evidence for change in future implementation of rapid population surveys in a post disaster setting.

Conclusion: The 2006 Louisiana Health and Population Survey provided timely, accurate population estimates critical to disaster management and recovery planning. Additionally there were several lessons learned from managing operations of this rapid, large-scale population survey in a post disaster setting. This presentation will focus on how operational challenges were overcome.
