Ireland has become the first country to be acknowledged as age-friendly by the World Health Organisation.

Representatives of the country's 31 local authorities were presented with charters by the WHO at a ceremony at Slane Castle, Co Meath.

The WHO says it gives recognition to the implementation of age-friendly policies and practices by all the local authorities under the Age Friendly Ireland Programme

It includes measures such as housing developments, libraries, airport guidelines, car parking and improved customer services and communication aimed at older people.

The WHO's Senior Health Advisor on Ageing, Alanna Officer, says it means "Ireland is committed to becoming a good place in which to grow old".

This year also marks the tenth anniversary of the launch of Ireland's Age Friendly Programme, which was introduced in a response to changing demographics.

The initiative is designed to enable older people to actively participate in the community by helping people to stay healthy and active and providing supports and services.

Since the 1980s, the country's population has been getting steadily older, with people living longer.

The number of people aged over 65 increased by 19% between 2011 and 2016.
