Underlying health and economic trends affect the vulnerability of the population to extreme weather . Poor housing quality is a risk factor for climate-related health threats . Homeless people lack access to temperature-controlled or structurally safe housing and often are excluded from disaster preparation and responses . These inequalities are reversible. For example, a government partnership with social housing providers in Australia improved the thermal performance of housing for low-income tenants . A postcode-level analysis of the vulnerability of urban populations to extreme heat in Australian capital cities  led to the development of an interactive website for purposes of planning and emergency preparedness  as well
