(2001); ^(14)Queensland Government (2008); ^(15) Gerritsen, Stefanoiannis and Galloway (2008); ^(16)Sourced from Australian and NZ census of population, 1991, 1996, 2001 and 2006. Australian data is by place of enumeration, NZ data by place of usual residence. Intercensal years estimated by linear interpolation. All populations are 18 plus. ^(17)Numbers in italics have been estimated from PGSI scores as discussed above; ^(18)The study was across jurisdictions and only surveyed part of those jurisdictions, hence population and EGM data was not readily available. As discussed elsewhere the result appears statistically anomalous; ^(19)Two casinos were operating in Tasmania in 1994 and 1996. Official gaming machine data is only retained since 1998. EGM numbers have been estimated by casino operators for these two years.
