Increasingly, studies are examining whether the incidence of natural disasters influences household migration. This paper examines whether the severity of natural disasters is important for migration decisions in Vietnam, rather than just examining their occurrence. Data for a sample of 1,003 farm households from the Vietnam Household Living Standard Survey are examined for the period 2006–2008. A residual generated regressor approach is adopted to isolate the direct impact of disasters on migration from the indirect impact they have on migration through reducing agricultural output and income. Findings suggest that more severe disasters are directly associated with a greater probability of migration. Furthermore, such outcomes are the same for poor households vis-à-vis their non-poor counterparts.
