The lack of a public toilet in many town centres and leisure areas has a hidden social cost — it effectively makes older people a prisoner in their own homes. Age UK, who used to be called Help the Aged, published a paper entitled "Nowhere to Go", which highlights this matter. Twelve per cent of older people (1.2 million) feel trapped in their own home, it says. Furthermore, about 100,000 never go out. The organisation suggests that lack of public toilets is a major factor in this, and the situation will worsen as toilet provision continues to decline.
