Editors have highlighted the following attributes while ensuring the content's credibility: Within a decade, New Zealand will officially become a "super-aged" society, with more than one in five residents—around 1.2 million people—aged 65 or older. Much of the debate about this profound demographic shift has focused on what it will mean for superannuation, hospitals, residential aged care and the workforce needed to support them.
But there's another figure worth considering: More than 95% of New Zealanders 65 and older currently live in private homes. This means preparing for an aging population requires as much attention to our houses, streets and neighborhoods as it does to retirement villages and hospital beds. Are sidewalks easy to navigate?
Can people get around without driving? Are shops, services and public spaces accessible? And do communities give older people opportunities to remain socially connected and involved?
Such questions are becoming increasingly important—and there is already an international model for addressing them. A World Health Organization framework aims to make communities easier places to live as people grow older—from the design of streets, transport and housing to social participation, civic life and health services. Yet, compared with many countries, New Zealand has been slower to embrace it.
Falling fertility rates are one reason our population is aging. But so are longer lives and fewer premature deaths, reflecting decades of improvements in health care and living standards. Seen this way, population aging is a success story, despite the negative way it is often framed in media and politics.
We also shouldn't automatically equate growing older with frailty or dependence. While health risks increase with age, nearly 60% of ill health among people 70 and older is linked to factors that can potentially be changed. The environments people live and move within can make a significant difference.
