Your health is shaped by far more than your doctor visits and your diet. Here is what is actually driving health outcomes — and why it matters for Detroit.

When we talk about health in America, we tend to frame it as a personal matter. Eat better. Exercise more. See your doctor regularly. Take your medication. The implication is that health is largely the result of individual choices — and that poor health outcomes reflect poor choices.

That framing is not just incomplete. It is wrong in ways that actively prevent us from solving the problem.

Public health researchers have established, with decades of evidence, that roughly 80% of health outcomes are determined not by medical care but by the conditions in which people are born, grow, live, work, and age. These are called social determinants of health (SDoH)— and understanding them is essential for anyone who cares about equity, policy, community development, or simply about why some neighborhoods in Detroit have dramatically shorter life expectancies than others just a few miles away.

What Are Social Determinants of Health?

The World Health Organization defines social determinants of health as the non-medical factors that influence health outcomes — the conditions of daily life and the structural forces that shape them. The U.S. Department of Health and Human Services organizes them into five core domains:

• Economic Stability: Employment, income, expenses, debt, medical bills, and support systems
• Education Access and Quality: Early childhood education, literacy, language, and higher education
• Health Care Access and Quality: Insurance coverage, provider access, quality of care, and health literacy
• Neighborhood and Built Environment: Housing quality, access to healthy food, crime and violence, environmental conditions, and transportation
• Social and Community Context: Social cohesion, civic participation, discrimination, and incarceration

These five domains are not independent. They are deeply interconnected. A person living in substandard housing is more likely to have a chronic health condition, which makes it harder to hold steady employment, which reduces income, which limits access to quality food and health care, which worsens the chronic condition. The cycle is not a personal failing. It is a predictable outcome of overlapping structural disadvantages.

Economic Stability — When Money Is Medicine

Poverty is one of the most powerful predictors of poor health outcomes in the United States. People living below the poverty line are more likely to develop diabetes, heart disease, asthma, and depression. They are more likely to die younger. And in Detroit, the numbers are stark: the city’s poverty rate consistently exceeds 30%, making it one of the poorest large cities in the country.

The mechanisms are direct. Low income means skipping medication because it costs too much. It means delaying a doctor’s visit because there is no paid sick leave. It means living in housing with mold, lead paint, or pest infestations because it is the only affordable option. It means choosing between food and heat in a Michigan winter.

For Detroit residents with disabilities — 43% of whom live below the poverty level — economic instability compounds an already difficult situation. Median annual earnings for a disabled Detroiter in 2023 were $23,405. When housing costs average over $12,000 per year, there is little left for anything else. The math does not work, and declining health is one of the consequences.

This is why Mayor Sheffield’s living wage executive order — $44,616 per year for all full-time city employees, effective July 2026 — matters beyond labor policy. It is a health intervention. A University of Michigan study found that only 36% of Detroiters earn a living wage. Closing that gap, even partially, has measurable downstream effects on health outcomes.

Education — The Long Reach of Early Disadvantage

The relationship between education and health is one of the most consistent findings in public health research. Adults with higher levels of education live longer, have lower rates of chronic disease, and are more likely to have health insurance. The effects show up early: children who attend high-quality early childhood programs have better health outcomes decades later.

Education shapes health through multiple pathways. It influences income and employment, which determine economic stability. It builds health literacy — the ability to understand medical instructions, navigate the health care system, and make informed decisions. It expands social networks and civic participation. And perhaps most fundamentally, it shapes a person’s sense of agency and control over their own life — what researchers call self-efficacy — which has direct effects on health behavior and resilience.

In Detroit, school quality and stability are deeply uneven across neighborhoods. Chronic absenteeism, which Detroit City Council has been actively addressing, is both a symptom and a driver of educational disadvantage — and therefore a health issue. Mayor Sheffield’s 120% increase in after-school programming funding and the free student bus rides initiative are not just education investments. They are public health investments.

Health Care Access — Necessary but Insufficient

Of the five SDoH domains, health care access is the one most people think of first — and the one that actually accounts for the smallest share of health outcomes. Estimates vary, but most research suggests that clinical care accounts for roughly 10–20% of what determines whether someone is healthy. That is significant. It is not the majority.

That said, access barriers are real and consequential. Detroit has significant primary care shortages in many neighborhoods. Residents without insurance — or with inadequate insurance — delay or skip care, which means conditions are diagnosed later, treated less effectively, and managed more expensively. Fear of ICE, raised repeatedly at Detroit City Council sessions earlier this year, has caused immigrant residents to avoid seeking care — a pattern that produces exactly the kind of preventable health deterioration and long-term disability that early intervention could have avoided.

Detroit’s HIV/AIDS data offers a useful counterpoint about what sustained, coordinated health investment can do. The city’s viral load suppression rate has climbed to nearly 88% — meaning fewer people are transmitting the virus. Seven community health workers are deployed citywide. Multi-year contracts worth over $10 million were approved by City Council in March 2026 alone. That is a model worth noting: not just treatment, but community-level infrastructure.

The placement of community health workers in every City Council district — announced through Mayor Sheffield’s administration — is a meaningful expansion of access. Bringing health resources into community centers and neighborhood spaces rather than expecting everyone to come downtown is the right direction.

Neighborhood and Built Environment — Your Zip Code as Your Prognosis

There is a phrase in public health that has become almost a cliché because it is so consistently true: your zip code is a better predictor of your health than your genetic code. In Detroit, this is not an abstraction. Life expectancy varies by more than a decade between neighborhoods within the city. The difference between living in a neighborhood with clean air, safe streets, accessible food, and functional infrastructure — and living in a neighborhood without those things — is measurable in years of life.

Housing quality is central to this. Substandard housing — with mold, lead paint, pest infestations, inadequate heat, and structural hazards — is directly linked to asthma, lead poisoning, respiratory illness, mental health conditions, and injury. More than 93% of Detroit’s housing stock was built before 1990, before modern health and accessibility standards took effect. The Leland Building crisis that dominated Detroit City Council sessions in February and March 2026 was not just a landlord accountability story. It was a public health story — one in which delayed enforcement produced measurable harm to real people, many of them seniors and people with disabilities.

Food access is another dimension. Detroit has long been described as a food desert — a term that captures the absence of affordable, nutritious food options in many neighborhoods. Residents who cannot access fresh produce consistently are more likely to develop diet-related conditions: diabetes, hypertension, obesity. Mayor Sheffield’s free fresh fruit and vegetable delivery program for senior buildings is a direct response to this. So is the Green Grocer Program for small businesses.

Environmental health belongs here too. The Kronos Concrete facility in District 3, raised at multiple City Council sessions this year, is a crushing operation that residents say is polluting the air in surrounding neighborhoods and schools. The connection between industrial pollution and respiratory illness, cardiovascular disease, and cognitive development in children is well-documented. A downzoning request has been submitted. That is an SDoH intervention.

Transportation shapes the built environment in ways that are easy to overlook. A resident who cannot reliably reach their doctor’s appointment because DDOT buses are unreliable is experiencing a health barrier — one that has nothing to do with their own choices. The $18.4 million ADA Complementary Paratransit contract approved by Council in March 2026, the 45 new buses, and the long-debated free student fare initiative are all health investments, not just transportation ones.

Social and Community Context — Discrimination, Belonging, and the Body

The fifth domain is the most diffuse — and in some ways the most powerful. Social and community context encompasses the relationships, institutions, and forces that shape whether people feel safe, seen, and supported in their communities.

Racism is a social determinant of health. This is not a political statement — it is a public health finding. Research consistently shows that the experience of racial discrimination produces measurable physiological effects: elevated cortisol, cardiovascular stress, disrupted sleep, accelerated cellular aging. The concept of “weathering,” developed by researcher Dr. Arline Geronimus, describes the cumulative biological toll of navigating a racist society — and it helps explain why Black Americans experience earlier onset of chronic disease and shorter life expectancy than white Americans even when income and education are controlled for.

Incarceration is a social determinant of health. People who have been incarcerated have significantly higher rates of chronic disease, mental illness, and premature death — and the communities with the highest incarceration rates bear the health consequences collectively, not just individually. Detroit neighborhoods that have seen mass incarceration have also seen the fracturing of social networks, the removal of working-age adults from families, and the economic destabilization that produces the other SDoH risk factors described above.

Social isolation is a social determinant of health. Research by former U.S. Surgeon General Dr. Vivek Murthy established that loneliness carries health risks comparable to smoking 15 cigarettes a day. For seniors in Detroit, for residents with disabilities, for veterans living alone — isolation is not an emotional inconvenience. It is a physical health risk.

Civic participation, conversely, is protective. Residents who feel connected to their community, who have mechanisms to voice their needs and influence decisions, show better health outcomes. This is one reason why the work of showing up at City Council, submitting public comment, and organizing at the neighborhood level is itself a public health activity. Democracy, when it functions, is a social determinant of health.

The Detroit Picture

Every major policy conversation happening in Detroit right now is an SDoH conversation, whether it is named as such or not.

• The housing accessibility crisis — 93% of the housing stock built before modern standards, seniors and people with disabilities in uninhabitable conditions — is an SDoH crisis.
• The $600 million in unaccounted property tax overpayments from 2009 that residents raise at Council every week — the financial instability that caused — is an SDoH issue.
• The fear among immigrant residents of seeking medical care because of ICE enforcement — that fear is an SDoH factor producing real health decline.
• The lead paint hazard reduction grant — $7.75 million targeting low-income families in older homes — is a direct SDoH intervention.
• The Disability Taskforce established by City Council in March 2026 — that is an institutional recognition that the structural conditions of disabled people’s lives are health issues.
• The RxKids maternal cash assistance program — giving mothers $1,500 during pregnancy and $500 monthly for six months after birth — is one of the most direct SDoH interventions any city government can make, because it addresses economic instability at exactly the moment it has the longest-lasting effects on child health.
• The 3,000 new midblock streetlights being installed this summer — safer streets mean more residents can walk outside, which means more physical activity, which means better cardiovascular health. Streetlights are a health intervention.

The point is not that every city service is secretly a health program. The point is that when we name the SDoH framework explicitly, we can evaluate policy decisions more honestly — asking not just “does this fix the immediate problem” but “does this change the underlying conditions that make the problem inevitable?”

What This Means for Advocacy and Policy

The SDoH framework has direct implications for how we organize, advocate, and make policy decisions at the local level.

• Siloed thinking is the enemy. Housing advocates and health advocates need to be in the same room. Transportation planners and public health officials need to share data. Workforce development programs and mental health services need to be connected. The conditions that drive poor health do not respect departmental boundaries, and neither should the solutions.
• Upstream investment pays off. It costs far less to ensure a child has stable housing, nutritious food, and a quality education than to treat the diabetes, depression, and cardiovascular disease that develop when those basics are absent. The math is clear. The political will to act on it is what remains in short supply.
• Data disaggregation matters. Health disparities are invisible when data is reported only at the city or county level. Neighborhood-level, race-disaggregated, disability-disaggregated data is what allows communities to name the problem precisely and hold institutions accountable.
• Community voice is not optional. The residents most affected by poor SDoH conditions are the experts on what those conditions actually look like. Designing solutions without centering their voices — in budget hearings, task forces, planning processes, and research — produces solutions that miss the mark.

The Bottom Line

Health is not distributed randomly. It follows the lines of wealth, race, housing quality, neighborhood safety, educational access, and civic power. That is not fate — it is policy. And what policy has created, policy can change.

Understanding social determinants of health means understanding that a city council budget vote is a health decision. That a building code enforcement failure is a health failure. That a bus that does not show up is a health barrier. That a living wage is a health intervention. That belonging — feeling seen and connected in your community — is medicine.

Detroit has the community, the advocates, the data, and increasingly the political will to act on this. The work is to make sure every decision — at City Hall, at the Health Department, at HRD, at the school district — is made with this framework in mind: not just what does this fix today, but what does this do to the conditions that shape our health for generations.
