Where sports facilities sit: Spatial inequality in access and residents’ mental health
This study demonstrates that in China, the spatial inequality of public sports facility access—not just the overall supply—is a significant determinant of residents' mental health, as uneven distribution increases depressive symptoms by reducing physical activity and neighborhood trust, with these adverse effects disproportionately impacting low-income, less-educated, and rural-registered populations.

Mental health is increasingly recognized not just as a matter of individual biology or personal history, but as something deeply shaped by the world we live in. For decades, public health experts have understood that where we live matters. Access to clean air, safe streets, and green spaces are all known to influence how we feel. Among these environmental factors, the ability to move our bodies through exercise stands out as one of the most powerful tools for protecting the mind. We know that regular physical activity can lower the risk of depression and anxiety. But a crucial question remains: does simply building more places to exercise help everyone equally? Or does the specific location of these facilities matter just as much as the total number of them? If a city builds many stadiums but they are all clustered in wealthy neighborhoods, leaving poorer areas without any nearby options, the overall count of facilities might look impressive, but the benefit to the community's mental well-being could be severely limited. This is the puzzle researchers set out to solve: looking beyond the total supply of public sports facilities to see how their uneven distribution across a city affects the mental health of its residents.
A team of researchers from Yangtze University and the Jingzhou Emergency Center in China tackled this question by examining the relationship between sports facility access and mental health across dozens of cities. They did not just count how many gyms or courts existed in a city; instead, they mapped exactly where these facilities sat in relation to where people lived. Using detailed digital maps and population data, they calculated a measure of inequality for each city. This measure told them how evenly the opportunity to exercise was shared among residents. In some cities, facilities were spread out so that most people lived within a reasonable walking distance. In others, the facilities were concentrated in a few spots, leaving large numbers of people in "blind zones" where no public sports venue was nearby. The researchers then linked this data to a massive, nationally representative survey of Chinese households, which included information on the mental health of over 44,000 individuals. By comparing the mental health scores of people living in cities with unequal access to those in cities with fairer distribution, they could isolate the effect of location from the effect of simply having more facilities.
The study found a clear and troubling pattern: the more unevenly sports facilities were distributed within a city, the higher the levels of depressive symptoms reported by its residents. This result held true even when the researchers accounted for the average number of facilities available. In other words, two cities could have the exact same total number of sports venues, but the city where those venues were spread out more fairly had residents with significantly better mental health. The researchers identified two main reasons why this happens. First, when facilities are far away or hard to reach, people simply exercise less. The extra effort required to get to a distant gym acts as a barrier, and without regular movement, the natural mood-boosting benefits of exercise are lost. Second, the uneven distribution damages the social fabric of neighborhoods. Public sports facilities are not just places to work out; they are places where neighbors meet, talk, and build trust. When these spaces are missing from certain areas, the sense of community weakens, and residents feel more isolated and disconnected. Both of these factors—less physical activity and weaker community bonds—directly contribute to higher rates of depression.
Perhaps the most significant finding was that this burden was not shared equally. The negative impact of unequal access fell hardest on those who could least afford it. Residents with lower incomes, less education, and those registered as rural residents in an urban setting suffered the most. These groups often lack the resources to travel far to find a facility or to pay for private gyms to make up for the lack of public ones. For them, the location of a public facility is not a minor convenience but a critical determinant of their daily life and mental well-being. In contrast, wealthier residents could more easily compensate for poor local access by driving to a distant facility or paying for private memberships, making the city's layout less critical to their mental health. The study also showed that older adults and women were more sensitive to these inequalities, likely because they rely more heavily on their immediate neighborhood for daily activities and social interaction.
This research challenges the common assumption that simply building more sports facilities is enough to improve public health. It suggests that the geography of public resources is just as important as the quantity. If a city invests in new venues but places them only in already well-served areas, it may be widening the gap in mental health between the rich and the poor. The study implies that for public investment to truly benefit everyone, planners must look at the map and ensure that facilities are placed where they are needed most, particularly in underserved neighborhoods. By treating the fair distribution of public amenities as a health priority in its own right, cities can ensure that the benefits of exercise and community connection are available to all their residents, not just those lucky enough to live near a stadium. The findings offer a clear lesson for urban planners and policymakers: where you build matters just as much as how much you build.
