This chapter focuses on older people’s living environments—where and how they live. Their living environments include the communities in which they live, with whom they share their accommodations, and the type of housing in which they live. As with most aspects of older adult life, great diversity is common in all of these areas. The opening scenarios indicate just that, with some older people aging in place, others moving to retirement communities with enticing amenities, and yet others sharing their accommodations with others. This chapter discusses living arrangements, housing options, and age-friendly communities for older adults. It stresses the importance of living environment to older people and outlines the factors that influence their decisions about where to live. The chapter also outlines the advantages and disadvantages of living alone and investigates the issue of homelessness among older adults.
