  • Environmental migration as short‐ or long‐term differences from a trend: A case study of Hurricanes Katrina and Rita effects on out‐migration in the Gulf of Mexico
Title: Environmental migration as short‐ or long‐term differences from a trend: A case study of Hurricanes Katrina and Rita effects on out‐migration in the Gulf of Mexico
Abstract An environmental event that damages housing and the built environment may result in either a short‐ or long‐term out‐migration response, depending on residents' recovery decisions and hazard tolerance. If residents move only in the immediate disaster aftermath, then out‐migration will be elevated only in the short‐term. However, if disasters increase residents' concerns about future risk, heighten vulnerability, or harm the local economy, then out‐migration may be elevated for years after an event. The substantive aim of this research brief is to evaluate hypotheses about short‐ and long‐term out‐migration responses to the highly destructive 2005 hurricane season in the Gulf of Mexico. The methodological aim is to demonstrate a difference‐in‐differences (DID) approach analysing time series data from Gulf Coast counties to compare short‐ and long‐differences in out‐migration probabilities in the treatment and control counties. We find a large short‐term out‐migration response and a smaller sustained increase for the disaster‐affected coastal counties.  more » « less

    Abstract We introduce the consideration of human migration into research on economic losses from extreme weather disasters. Taking a comparative case study approach and using data from the Federal Reserve Bank of New York/Equifax Consumer Credit Panel, we document the size of economic losses attributable to migration from 23 disaster-affected areas in the United States before, during, and after some of the most costly hurricanes, tornadoes, and wildfires on record. We then employ demographic standardization and decomposition to determine if these losses primarily reflect changes in out-migration or the economic resources that migrants take with them. Finally, we consider the implications of these losses for changing spatial inequality in the United States. While disaster-affected areas and their populations differ in their experiences of and responses to extreme weather disasters, we generally find that, relative to the year before an extreme weather disaster, economic losses via migration from disaster-affected areas increase the year of and after the disaster, these changes primarily reflect changes in out-migration (vs. the economic resources that migrants take with them), and these losses briefly disrupt the status quo by temporarily reducing spatial inequality.

    After Hurricane Katrina decimated the Gulf Coast in 2005, thousands of Latinx immigrants arrived in the region to work in reconstruction, one case of the growing and global phenomenon of disaster migration. Drawing on newspaper content analysis, in-depth interviews with immigrant service providers, and archival materials from Mississippi for the years surrounding Hurricane Katrina (2003-2009), we ask what reception these disaster migrants encountered upon arrival and how that reception changed as they settled permanently in the state. We find that public discourse about immigrants became markedly more positive when disaster migrants arrived en masse, with the media and public characterizing immigrants as valuable, hard workers. Negative characterizations shifted to portray immigrants as drains on public resources. However, these changes were temporary. By 2009, public debate about immigrants reverted to pre-disaster trends with only one exception. Across our study period, we find a steady rise in claims that immigrants faced racism and discrimination. Our findings suggest that disasters may briefly transform the social and cultural bases of material inequalities but are unlikely to produce lasting change.

    Abstract Extreme weather events, such as hurricanes with intense rainfall and storm surges, are posing increasing challenges to local communities worldwide. These hazards not only result in substantial property damage but also lead to significant population displacement. Federal disaster assistance programs are crucial for providing financial support for disaster response and recovery, but the allocation of these resources often unequal due to the complex interplay of environmental, social, and institutional factors. Relying on datasets collected from diverse sources, this study employs a structural equation model to explore the complex relationships between disaster damage (DD), social vulnerability (SV), public disaster assistance (PDA), the national flood insurance (NFI), and population migration (PM) across counties in the contiguous US. Our findings reveal that communities with lower SV tend to experience higher levels of DD across US counties. SV is negatively associated with PM, PDA, and NFI, both directly and indirectly. Furthermore, PDA is positively linked to PM, whereas DD has a direct negative effect on PM but an indirect positive effect through PDA.

    Background: The amount of literature on environmental migration is increasing. However, existing studies exhibit contradictory results. A systematic synthesis of the environment–migration relationship is much needed. Objective: This study summarizes research findings, calculates the effect sizes of environmental stressors, identifies publication bias, and investigates heterogeneous environmental effects on migration. Methods: We collected 3,380 estimates from 128 studies published between 2000 and 2020 to explore the environment–migration relationship and performed weighted instrumental variable regression to unveil the heterogeneous environmental effects on out- and net migration. Results: The majority of environmental stressors were not important predictors of out- and net migration. Among the results showing environmental impacts on migration, 58% and 68% reported that environmental stressors increased out- and net migration, respectively, while 58% reported that environmental stressors decreased in-migration. The overall environmental impact on migration was small; however, disaster-related stressors showed a medium effect, and rapid-onset stressors had a stronger impact than slow-onset ones. Multivariate meta-regression analyses demonstrated that environmental stressors were more likely to trigger internal migration than international migration and that developed countries were less likely to experience out-migration. Rapid-onset environmental stressors did not increase out-migration but played an important role in decreasing net migration toward environmentally stressed areas. Meanwhile, we also found a publication bias toward studies showing a positive relationship between environmental stressors and migration in the previous environmental migration literature. Conclusions: Environmental stressors may affect migration; however, the environmental effect depends on migration measurements, environmental stressors' forces and rapidity, and the context in which migration takes place. Contribution: This study contributes to migration studies by synthesizing and validating the environment–migration relationship and enhancing our understanding of how and under what circumstances environmental stressors may affect migration.

    Amenity migration in the Intermountain West is a rapidly evolving process that has greatly impacted wellbeing in many rural communities over the past several decades. While the impacts of amenity migration have been discussed through both individual community case studies and cross‐community comparative analysis, there is an ongoing need for research that continues to build upon our understanding of amenity migration's effects on individual and community wellbeing. Remote and hybrid work opportunities, expanded during the COVID‐19 pandemic, have allowed for an increasing number of people to live part or full‐time in highly desirable rural locations, particularly those proximate to larger urban areas. In this paper, we discuss the historical and current trends of amenity migration in Kittitas County, proximate to Seattle, Washington, on the eastern slope of the Cascade Mountains. Drawing upon perspectives shared in 80 interviews with key informants and community members about community wellbeing in three towns, we discuss the implications of amenity migration for the perceived quality of life of both longer‐term residents and newer community members. Additionally, the setting and scope of this research allows for comparison between high‐amenity rural communities with larger recreation economies, and adjacent less—amenity‐based rural communities. Findings indicate that amenity migration continues to evolve and impact community wellbeing, primarily via community cultural changes and socioeconomic and housing inequality. However, there are nuanced geographical and longitudinal differences in the impacts of amenity migration. Additionally, participants perceived an increase in amenity migration patterns and impacts in the years following the COVID‐19 pandemic. To conclude, we discuss ongoing and potential initiatives that may help support community wellbeing, as well as possibilities for further improvements in policy and planning to equitably increase the quality of life for all residents.
