The Irish Council for Social Housing has called on Minister for Housing Darragh O'Brien to take "decisive action" on a housing plan for older people following the impact of Covid-19.
It said such a plan will be a critical challenge for the Government.
The organisation, which represents approximately 270 member organisations, is holding its annual general meeting today.
The ICSH said it has identified five challenges the Government needs to address to ensure it is responding to the housing needs of the population.
They include returning to a full-scale social housing build in the aftermath of Covid-19, developing a new cost rental scheme, housing for older people, and preventing a resurgence of homelessness.
The ICSH also said that approved housing bodies need to be reclassified.
According to the Central Statistics Office, the population of people aged 65 and over will increase from 629,800 in 2016 to nearly 1.6m by 2051.
