We analyzed the migration consideration factors of residents from the Mississippi River Delta in southern Louisiana, which is under the influence of rising sea levels, subsiding land, and increasing flood risks. Through the use of a telephone survey of 1,125 adult individuals in twenty-four parishes, we gathered the demographic data and flood risk experiences and perceptions of each respondent. The data were analyzed through descriptive statistics, means comparisons, and logistic regression to determine the factors with the highest influence on migration consideration. Results show that 21.5 percent of respondents considered moving, and they were mostly renters, were mostly younger, had experienced flooding before, and were less satisfied with their current living condition. Flood risk was found to be an important deciding factor, but it is not the most important one. Instead, economic opportunities have a greater effect on respondents’ desire to move or stay. The findings provide useful information and insights into the planning and management of a flood-prone region and whether managed retreat or other mitigation measures would be effective.

我们分析了路易斯安那州南部密西西比河三角洲居民的迁移考虑因素，这些因素受到海平面上升，土地沉降和洪水风险增加的影响。通过对二十四个教区的1,125名成年个体进行电话调查，我们收集了每个受访者的人口统计数据，洪水风险经验和看法。通过描述性统计，均值比较和逻辑回归分析数据，以确定对迁移影响最大的因素。结果显示，有21.5％的被调查者认为搬家，他们大多是房客，大多是年轻，以前曾遭受过洪灾，对当前的生活条件不满意。发现洪水风险是一个重要的决定因素，但这不是最重要的。取而代之的是，经济机会对受访者的迁移或留下的意愿有更大的影响。这些发现为洪水多发地区的规划和管理以及有管理的撤退或其他缓解措施是否有效提供了有用的信息和见识。
