Our study shows the potential for a negative cyclic  relationship between failures in infrastructure provision and population loss. While population losses have not yet accelerated, we found that many residents of Flint, Michigan are considering leaving the city because of a water crisis. If a large proportion of residents leave, the quality of the city’s infrastructure will further erode as the tax base continues to decline. We found that perceptions of the water’s safety and its long-term health effects—rather than sociodemographic variables or actual water lead levels—predict whether a resident considers leaving. Further, resident responses did not vary by demographics or home location—meaning that policy makers cannot target retention initiatives to one group or section of the city.

What is already known: The literature on migration in developing nations indicates that poor quality infrastructure is a “push” factor because people leave places that cannot provide water or other basic services. It is conceivable that the same phenomenon could occur in the U.S. as infrastructure deteriorates. This issue has not yet received a lot of attention in the academic literature or mainstream media; however water systems in the U.S. are now just reaching the point where they are old and failing.

What our study adds: The study adds to the paucity of work on the relationships between water infrastructure and population dynamics. Although itUses empirical analyses and a case study approach focused on the Flint, Michigan water crisis, the findings have wider implications.

Implications for policy and practice: Flint may be one of the first cities in the U.S. to experience a man-made, catastrophic water infrastructure failure on a large scale. It is conceivable that other legacy/shrinking cities could face similar challenges as their infrastructure ages and is not maintained due to financial constraints stemming from deindustrialization. This study emphasizes how disinvestment in water infrastructure has implications for community development,,  cities’ long-term financial health, and ultimately their sustainability. We argue that it is important for planners and policy makers to be aware of the public’s perception of infrastructure quality.
