In particular, those that show the impact of policies in cities at advanced stages of the ageing process will become useful information for cities in the early stages of ageing. One such example is the EU Ageing Report (European Commission, 2012a), which includes a set of indicators that illustrate expenditure projections for a large older population, covering pensions, healthcare, long-term care, education and unemployment. Internationally applicable indicators that help assess the social sustainability of cities and their urban form are particularly important.
