Long-term missing persons in Australia

Data collected on persons considered a long-term missing person (LTMP) as at 19 May 2020. Persons included were listed as LTMP on National Missing Persons Coordination Centre (NMPCC) and Australian Missing Person Register (AMPR) websites on 19 May 2020. Searches were carried out using the LTMP’s name including variations and/or alternate names used or reported as used by that individual. This data was collected to determine if publicly available data could be gathered for the purposes of creating a dataset. This dataset was analysed to establish if such a dataset could be compared to results from existing studies and if so where those results similar or different. Having such a dataset created from publicly available data provided an additional avenue for datasets as opposed to relying only on stakeholder's information. Data was collected from Coroner's reports, law enforcement media releases (including archived) NMPCC and/or AMPR, Trove – online library of current and historical information obtained from universities, museums, galleries, and archives, crime stoppers, ancestry records, cemetery records/images, news/media reports, social network/media platforms i.e., LinkedIn, Facebook, and random ad hoc websites/pages.
