After a Disaster: Lessons in Survey Methodology from Hurricane Katrina

Abstract

In 2005, the National Science Foundation funded a number of projects to study the impact of Hurricane Katrina. The current article provides an overview of several research approaches used to conduct post-Katrina research. Each method had some advantages and disadvantages. The post-disaster context meant that experience from traditional survey methods often did not apply. Comparisons of advantages and disadvantages associated with each sampling method serve to

Breakup of New Orleans Households After Hurricane Katrina

“…Of these, completed surveys were conducted for 147 households, giving an adjusted response rate calculated at 51% after subsampling outstanding cases for the final stage of fieldwork. This compares favorably with the 35% to 39% response rates of the only other survey effort to have attempted to contact pre‐Katrina residents of Orleans Parish, including those who had moved outside the immediate region (Henderson et al, 2009, p. 75). Multivariate analyses of the probability of nonresponse by survey operational characteristics, including flood‐depth strata, and by area sociodemographic characteristics as assessed from 2000 U.S. Census block or block‐group statistics, were conducted by Sastry (2009b).…”

Pre-landfall evacuee perception of the meteorological hazards associated with Hurricane Gustav

“…This method was employed due to the time-sensitive nature of data collection, the exploratory nature of the analysis, and to survey as many evacuees as possible. Henderson et al (2009) noted the utility of employing convenience sampling when they used this method to query displaced residents in the aftermath of Hurricane Katrina. Using this sampling method, evacuees stopping at each rest stop were approached at random by a member of the survey team at various locations on the grounds of the rest stop, with every effort made to ensure only one member of a vehicle or caravan of vehicles was surveyed.…”

Modeling and simulation of extreme floods emergency management between hierarchical governments using evolutionary game

“…Especially in the past 20 years, affected by global climate change, extreme floods occurred almost every year [1] . According to statistics on intensity, frequency, duration, geographic distribution and area of influence, extreme floods are tending to normalization [2,3] .…”
