传闻证据表明，一个地区的灾难性事件导致生育率上升。在本文中，我们衡量这种生育率的影响，风暴咨询数据和生育率数据的大西洋和海湾沿岸的美国县。我们发现，低强度的风暴massories与一个积极的和显着的生育率的影响，高强度massories有一个显着的负生育率的影响。随着咨询类型从最不严重到最严重，特定咨询类型的生育效应从正到负单调递减。我们还发现了一些其他有趣的人口效应。
Anecdotal evidence has suggested increased fertility rates resulting from catastrophic events in an area. In this paper, we measure this fertility effect using storm advisory data and fertility data for the Atlantic and Gulf-coast counties of the USA. We find that low-severity storm advisories are associated with a positive and significant fertility effect and that high-severity advisories have a significant negative fertility effect. As the type of advisory goes from least severe to most severe, the fertility effect of the specific advisory type decreases monotonically from positive to negative. We also find some other interesting demographic effects.
