Abstract

Work joint with Paige Maas, Eugenia Giraudy, and J.W. Schneider at Facebook.

In this talk we introduce a novel method of data collection for post-disaster displacement and examine its application to the specific case of the 2019-2020 Australian Bushfires. We build on recent work on geo-located data and use social media as a sampling frame for surveying hard-to-reach populations. This survey was conducted two months after the disaster events under study. Specifically, we leverage Facebook geo-location data to build a stratified random sampling frame for Green Wattle Creek Fire in Eastern New South Wales and the Cudlee Creek Fire in Adelaide Hills, South Australia. Surveying post-disaster and locating respondents has historically been difficult and expensive (Sastry, 2009); and an alternate sampling frame than classic phone, address or in person sampling is needed. Using our novel survey mode, we estimate that 17,973 (17,741; 18,205) people were displaced for at least one night between January and February 2020 in the Adelaide Hills, South Australia region. In our sample of respondents who were in the disaster affected regions, 25.5% were displaced at least one night; of those displaced, 42% returned home within a week, 32% within two weeks, 13% within a month and 9% were still displaced at the time of the survey.
