12% of Princeton households have no vehicle (11% in Mercer County). A companion who drives can turn a week at home into appointments, shopping and visits.

Of the 3,999 Princeton residents aged 65 or older, 608 are 85 or older (15%). 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.

1,936 Princeton households headed by someone 65 or older own their home and 494 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 321 older Princeton residents (8.2%) live below the poverty line (9.6% in Mercer 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 35% of Princeton residents aged 5 and over speak a language other than English at home. The most common are Chinese (2,803), Spanish (1,815), other Indo-European languages (1,633). If the person you care for is more at ease in one of these languages, say so in your posting; many caregivers list the languages they speak.

Cost

What companion care costs in Princeton

At the New Jersey median aide wage of $17.83 an hour, 20 hours of help a week comes to about $1,545 a month in wages, which is 11% of the $14,107 monthly median income of Princeton households headed by someone 65 or older. Private rates are agreed directly with the caregiver, so yours may be higher or lower. New Jersey's minimum wage is $15.92 an hour (U.S. Department of Labor table, updated July 1, 2026).

Hiring directly, you agree the rate with the caregiver and usually become the household employer (U.S. Department of Labor rules). Some families qualify for programs that pay for care at home; see Medicaid programs for family caregivers: who can be paid, and the rules in 12 states.

Before you hire

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.
