We all age — some early, some late — depending on our health and how well we care for ourselves. As we age, our bodies slow: muscle mass declines, reflexes and thinking speed ease off, balance becomes less sure, and arthritis makes movement harder. Beyond these changes come higher risks of diabetes, heart disease, stroke, and hypertension, whose symptoms make daily activities harder still.
Traditionally — and still today in many societies — it was understood that adult children would gradually take over tasks and shift into caregiving roles. In America, that structure transformed within living memory.
How America stopped living together
U.S. census data tells a stark story: in 1900, 57% of older Americans lived with their adult children. By 1980, only 17% did — a 70% decline in 80 years, one of the most dramatic social transformations in American history. We went from a society where more than one in two older people lived with their children to one where fewer than one in five did.
What drove it? World War II and its aftermath disrupted families; the post-war suburban boom let young families establish independent households; Social Security reduced elders' financial dependence on children; improved healthcare extended independent years; career mobility scattered families across the country; and smaller families meant fewer children to share caregiving. By the 1970s and 1980s, solo living among older adults reached its peak.
The institutional answer — and its price
Those who could no longer live alone found themselves without the traditional family safety net, and institutions filled the gap. After Medicare and Medicaid arrived in 1965, the nursing home industry expanded explosively. By the 1980s, families seeking alternatives to institutional care embraced assisted living — a more home-like model that arrived perfectly timed for both demographic need and real-estate opportunity.
Assisted living operates primarily as a private-pay business: residents typically pay several thousand dollars a month — national surveys put the median cost around $5,000 monthly (Genworth Cost of Care Survey) — funded from home equity, retirement savings, and family resources. The model banks on middle-class homeowners liquidating a lifetime of accumulated wealth to maintain independence and dignity.
And everything comes with a price beyond money. Research consistently finds depression to be far more common among older adults in institutional settings than among those living in their own homes. Despite marketing promises of "active communities," these facilities can create artificial environments — standardized routines, relationships among strangers thrown together by circumstance, activities designed by staff rather than emerging from personal interests. Researchers describe an "institutionalization creep": the gradual loss of personal agency. No amount of amenities replaces the psychological benefit of living somewhere you are known, valued, and woven into the fabric of daily life.
Consider the contrast: at home, you might wake to tend your garden, chat with a longtime neighbor over coffee, help a younger housemate with advice, and keep the rhythms and spaces that have defined your identity for decades.
What people actually want
Three out of four adults aged 50 and over want to stay in their own homes as they age (AARP, 2024) — among the strongest and most consistent preferences in housing research, across demographics and income levels. Yet our housing and care systems largely funnel people toward expensive institutional options most actively want to avoid. That gap between preference and reality is a market failure: an industry built around what providers want to offer rather than what people actually want.
Working with modern life, not against it
We cannot rewind a century of change. Careers demand mobility; technology connects the globe; it is unrealistic to expect young people never to leave their hometowns. But we can create solutions that work with modern realities.
If you cannot be there for your own parents because of where your career has taken you, you can be there for an older neighbor where you live — while someone just like you does the same for your parents back home. A network of intergenerational care that honors both mobility and the human need for support.
The sharing economy has already proven the mechanics at scale. Uber transformed transportation using existing cars; Airbnb transformed travel using existing homes. Both overcame trust barriers through verification, reviews, and platform accountability. The same model applies to housing for older adults: using the bedrooms we already have, and building trust through screening, verified identities, and professional oversight.
The power of homesharing
Homesharing in a homeowner's spare bedroom provides help, companionship, and income without anyone moving out of the home they love — directly answering that overwhelming preference to age in place. The economics work for both sides: tenants typically pay well below the cost of a full apartment for a furnished room in a shared home, while homeowners earn meaningful monthly income — on ResidAlly, furnished rooms list for $400 to $800 per month in Lubbock and up to $1,200 or more in larger Texas cities. Earnings vary by room and features.
The research on intergenerational contact points the same direction: regular connection across generations is associated with lower rates of depression, better cognitive engagement, earlier detection of health issues through daily interaction — and, per the U.S. Surgeon General, strong social connection protects against risks as serious as heart disease, stroke, and dementia. Large studies have associated living alone with a 32% higher risk of early death (Holt-Lunstad et al., 2015). The loneliness epidemic affects young adults too; shared homes create natural support systems for both generations.
Addressing the safety question
The biggest barrier to adoption is safety — a valid concern. But professional screening, legal frameworks, and ongoing support address it more effectively than leaving people isolated. On ResidAlly, tenants complete TransUnion background checks, homeowners complete Checkr checks, identities are verified, conversations happen in secure in-app messaging, leases are signed digitally on an attorney-drafted Texas template, and payments run through the platform. The sharing economy already solved the trust problem at scale; homesharing applies that solution where it matters most.
The vision forward
Imagine neighborhoods where young professionals live with and support older homeowners, where technology keeps distant family involved, and where aging in place becomes not just possible but enriching for everyone. This isn't about going backward — it is about moving forward with solutions that honor both modern mobility and the timeless human need for connection and care.
The question isn't whether we can afford to try this model. Given what institutional care costs in both dollars and wellbeing, it's whether we can afford not to.
