Companion Care in Mercer Island, WA: the local picture
About 1,206 residents of Mercer Island aged 65 or older live alone, 22% of older residents in households (28% in King County). They are the people companion care is usually for: mostly independent, but on their own for long stretches of the day.
5.7% of Mercer Island households have no vehicle (11% in King County). A companion who drives can turn a week at home into appointments, shopping and visits.
Of the 5,610 Mercer Island residents aged 65 or older, 1,233 are 85 or older (22%). Before the first visit with someone in that oldest group, ask the family about hearing, eyesight, walking and any memory changes, so the visit is planned around them.
2,312 Mercer Island households headed by someone 65 or older own their home and 957 rent. A companion visiting a house may also help with mail, light chores and keeping an eye on things; in an apartment building, ask whether visitors sign in.
About 289 older Mercer Island residents (5.3%) live below the poverty line (9.3% in King County). For them, Medicaid home and community-based services or the local Area Agency on Aging may cover some companion or homemaker hours, depending on the state program; private pay is not the only route.
About 26% of Mercer Island residents aged 5 and over speak a language other than English at home. The most common are Chinese (2,302), other Indo-European languages (1,469), Korean (593).

What to know before hiring a companion caregiver
Isolation is a health risk, not only a mood. The National Academies of Sciences, Engineering, and Medicine found that nearly one in four Americans aged 65 and older living in the community is socially isolated, and linked isolation to higher risks of dementia, heart disease and early death (2020 report).
Questions worth asking: What do you enjoy doing with the people you care for? Are you comfortable driving, and is your car insured for passengers? How do you handle a client who does not want company at first? More in our companion care guide.
