Household experience of gambling-related harm by socio-economic deprivation in New Zealand: increases in inequality between 2008 and 2012

Although problem gamblers make up a small proportion of the New Zealand population, those who are living in more deprived areas at higher risk of harm from their own or someone else's gambling. The global financial crisis in 2008 has been linked with changes in gambling behaviour and with increases in inequality between areas of relative deprivation. Nationally representative datasets from in-home face-to-face health surveys in 2008, 2010 and 2012 were analysed to investigate changes in gambling behaviour, experiences of household-level harm related to gambling, and the association with economic deprivation. Although overall gambling participation had dropped, the experience of gambling harm at the household level was significantly higher in 2012 compared with 2008 and 2010. The increase in harm was experienced disproportionately by those in more deprived areas, who were 4.5 times as likely to experience gambling-related arguments or money problems. We consider possible explanations including more harmful gambling behaviour as a response to financial stresses, decreasing household resilience to financial stresses, and the concentration of more harmful forms of gambling product in more deprived areas. Causes of gambling harm in deprived communities, and the vulnerability of households in these communities, should be addressed if inequalities are to be reduced.
