The Displaced New Orleans Residents Pilot Study was designed to examine the current location, well-being, and plans of people who lived in the city of New Orleans when Hurricane Katrina struck on August 29, 2005. The study is based on a representative sample of pre-Katrina dwellings in New Orleans. Fieldwork focused on tracking respondents wherever they currently resided, including back to New Orleans. Respondents were administered a short paper-and-pencil interview by mail, by telephone, or in person. The pilot study was fielded in the fall of 2006, approximately one year after Hurricane Katrina. The goal of DNORPS was to assess the feasibility of the study design and thereby to lay the groundwork for launching a major longitudinal study of displaced New Orleans residents.

ICPSR only holds the public data for the pilot study. The main study (DNORS) was carried out 2009-2010. These data are not yet publicly available, but for more information, visit the RAND Corporation website.

The NIH-funded Katrina@10 Program consists of an interrelated set of three primary data collection projects that focus on specific sub-populations who were uniquely affected by Hurricane Katrina: households along Louisiana and Mississippi's Gulf Coast, low-income parents from New Orleans, and Vietnamese families living in New Orleans. In addition, the program contains two secondary analyses of data that are more broadly representative of the overall affected population, and three cores (Administrative, Data Collection, Data Management and Dissemination) to support the set of research projects. The following research questions represent the studies together as a whole:

• How well does the socio-ecological model of disaster recovery developed by the research team (Abramson et al. 2010) predict recovery across the three cohort studies?
• How do trajectories of long-term recovery differ among and within these sub-populations?
• How do the trajectories of recovery compare to those of mainstream populations?
• How do the effects of predisposing factors (such as poverty) and degree-of-impact (such as flooding depth) vary among the three sub-populations?
• How do interpretations of the disaster, resilience, and recovery differ among respondents?
• What are the determinants of long-term recovery in domains such as mental and physical health, socio-economic status, and community and social roles? How are these domains related to each other across individuals and across sub-populations?

The Katrina Impacts on Vietnamese Americans in New Orleans (KATIVA NOLA) study was a longitudinal study interested in measuring the impact of Hurricane Katrina on Vietnamese-Americans living in New Orleans. The original sample was taken in summer 2005 and was followed by three rounds of short and medium-term data collection in the 5 years following Katrina. This study measured a variety of outcomes, including physical and mental health, economic stability, housing stability, and social ties, to examine the long-term recovery trajectories of participants.

The data in this collection are from an additional, long-term follow-up survey conducted between 2017 and 2019. A public-use version (DS1) and restricted-use version (DS2) are available. Open-ended responses, continuous respondent age, continuous total household income, and a variable indicating exposure to specific flood events have been masked in the public-use version. These items are available in the restricted-use version.
