Public health officials and urban planners have long known that one’s ZIP code is an especially reliable indicator of educational attainment, lifetime earnings and even life expectancy.

ZIP code is also a great indicator of risk for disease transmission. Cities across the United States, lower-income communities of color are experiencing disproportionately high rates of COVID-19 infection, hospitalization and death. One set of explanations for these geographical disparities focuses on the individual circumstances of neighborhood residents. Indeed, for the 60% of low-wage U.S. workers lucky enough to have kept their jobs through the crisis, those in “essential service” positions like construction, food preparation and retail cannot simply Zoom with colleagues from home.

They often rely on family members, who may themselves be in high-risk age groups, for child care and depend on crowded public transit for their commutes before returning home to crowded apartments or houses. And those with limited English fluency often struggle to obtain reliable health information. Lacking health insurance often leads people to delay seeking medical care, sometimes resulting in severe health consequences.

Neighborhood maps also reveal other influences. For example, maps of COVID-19 hospitalizations overlap with maps showing lack of health insurance and access to preventive medical care. Yet few people have focused on how neighborhood characteristics, or environmental factors, might play a role in virus transmission. Is it possible that neighborhoods themselves are making people sick?

It is likely. The CDC says that people with asthma are at higher risk for severe illness if they contract COVID-19, and rates of asthma are notoriously elevated near highways like those surrounding Valverde. Diabetes, hypertension and obesity rates are also strong risk factors for virus contraction; these conditions are linked to physical activity and diet, which are themselves directly influenced by access to quality walking and biking infrastructure, parks and healthy food outlets, all features that tend to be lacking in disadvantaged neighborhoods.

The legacy of redlining

Why does this geographical clustering of disadvantage and privilege occur in cities around the U.S.? Much of our present-day disparities in health, wealth and social mobility can be traced back to the 1930s, when Valverde and similar neighborhoods were “redlined” by the Home Owner’s Loan Corporation. In this racist practice, banks drew red lines on a map around neighborhoods with populations of color, restricting lending in these places and starving them of investment for generations to come.

The legacies of redlining are well-documented. Due to decades of disinvestment, once-redlined neighborhoods have higher poverty rates, lower-performing schools, more segregation, lower social mobility, greater exposure to extreme heat, fewer parks, higher gentrification rates, and more indicators of urban decline than those that were not. Property is also the primary way that families build and inherit wealth in America; the median white family now holds nearly 10 times the wealth of the median black family and several times that of the median Hispanic family.

Decades of legally sanctioned disinvestment and segregation made redlined neighborhoods fertile ground for the siting of polluting industrial facilities and two interstate highways, one of which runs directly through Valverde – a familiar story in cities around the United States.

These inequities have contributed to vast differences in levels of social vulnerability – the constellation of individual and environmental circumstances that weaken a community’s ability to prepare for and respond to crises like this pandemic. Mapping scores on the CDC’s Social Vulnerability Index in Denver reveals how these clear patterns of disadvantage coincide with COVID-19 hospitalization rates.

Building healthier cities

Given these realities, how can cities best contain this virus and plan for the next pandemic? A decentralized, health equity-oriented approach to fighting the epidemic that brings testing and support services into our most historically vulnerable neighborhoods can increase access to preventive health care and improve health across entire communities.

In the short term, critical efforts can include widespread free testing events in vulnerable neighborhoods, along with distribution of free hand sanitizer, cleaning supplies and masks, which also helps ensure that at-risk residents do not have to travel on crowded public transportation to shop for these items. This is also an opportunity to link uninsured residents to health care coverage and primary care providers.

Health care workers in these dispersed clinics are trained to provide culturally and linguistically appropriate medical information about what to do if one feels sick, what testing and treatment options exist and how to prevent further spread of COVID-19.

In the longer term, urban planners have demonstrated how a commitment to building healthy urban environments – those that prioritize walking and cycling, promote recreation, produce more affordable housing, allow residents to access healthy food locally and provide public transportation options – can have long-lasting impacts for all residents.

In addition, locating neighborhood health centers in at-risk neighborhoods has been proven to improve health and build a sense of community trust that can be instrumental in times of crisis. America is at a crossroads, and cities can embrace this opportunity to address health disparities. Health care officials and urban planning professionals are beginning to work together to help lift communities from the legacy of discriminatory policies.

By employing interventions that acknowledge the power of place, the country can mitigate harm from the current epidemic and help create more just, healthy and resilient communities that are better prepared for future challenges.

The Milwaukee Independent began reporting on what was then referred to as the mysterious “Wuhan Virus” in January 2020. Other local media did not picked-up on the story until many weeks later. Our early features focused on the economic impact, social issues, and health concerns long before other Milwaukee news organizations even mentioned the coronavirus. Over the following year, we have published hundreds of articles about the pandemic and how it has affected the lives of Milwaukee residents. This extensive body of work can be found on our COVID-19 Special Report page, a chronological index of links by month. Our editorial voice remains dedicated to informing the public about this health crisis for as long as it persists.
