Many older adults want to stay in their own homes for as long as possible. In England, about one in three people aged 65 and older falls at least once every year. Older adults living in crowded homes had a 3.3% higher risk of falling, possibly because it is harder to move around safely or avoid obstacles. Simple changes such as repairing electrical and plumbing faults, improving lighting, and reducing clutter may help many older adults remain safe and independent. Overall, this large long-term study provides strong evidence that the condition of a home can affect the health of older adults.
