In a 2019 survey in the US found that 61% of elderly people prefered to age in their own home. Nearly 60% of adult children of those surveyed had concerns about their parents living in the own home into old age.
There are a number of minor modifications can be made to improve livability for older people in their own homes. The biggest idea from the literature for successful living in your own home as you age is planning. In other words recognising and removing hazards before an accident.
Planning also means organising help with gardens, house manitainance, and self care early.
These can be privately funded and some are also a funded by the Ministry of Health.
