E-book The Demography of Disasters : Impacts for Population and Place
The demographic make-up of populations at the time of disaster determines whois impacted and the extent of impacts on residents and others. Improving technolo-gies, improved warning systems, investments in disaster mitigating infrastructureand improving community preparedness and response in the face of disasters areexamples of attempts to reduce disaster impacts. While a range of studies havelooked at demographic impacts from individual disasters, these are generally short-term focused and concentrated on post-event analysis and evaluation. Our aim inthis chapter and generally in the book is to extend the nascent work to improvedisaster policy and planning process through the growing knowledge about thedemography-disaster nexus.Both the study of disasters and demographic issues themselves are broadconstructs in their own rights. While it may seem obvious to link the two, as wehave in this book, disasters can impact on populations and change populations inmultifarious, obtuse and complex ways. Populations may be the root cause of alocalised disaster or indeed be the main ‘victims’. Disasters can speed up pre-existingdemographic changes or create new population profiles through immediate impactsand human reactions to such events (as we learn in Chap.2by Karácsonyi et al.,in Chap.5by Carson et al. and in Chap.7by Bird and Taylor). Their impacts ondemographic change can occur on a complex time–space continuum which mayinvolve feedback loops. Most obvious are deaths and injuries, out-migration andthe temporary relocation of residents and others from affected areas which rapidlyand noticeably alter the pre-existing demographic profile of a town or region. Morevulnerable cohorts (like the elderly) are often disproportionately impacted. Disas-ters may also affect the gendered demography of places, as discussed in Chap.9by Barnes. Disasters may encourage populations not immediately affected by thedisaster at hand to adjust their demographic behaviours, such as around fertilityor migration. Such feedback loops may be complex, unknown and unpredictable,altering not only the population profile but the economies and social fabric of townsand regions well into the future (see for example, Chap.5by Carson et al., Chap.6by King and Gurtner, or Chap.8by Zander et al.).
