Public schools have long been considered a public good in America. But that ideal is far removed from the lives of millions of schoolchildren. Public school district doors are not always open to every student in a community. Instead, geographic boundaries of school districts mostly determine who is eligible to attend district schools -- limiting access to those who can afford to live within those boundaries. The public school system should provide every student with a fair chance to achieve the American dream. However, in far too many communities, the structure of district boundaries and the market for rental housing limit options for the highest-need students while simultaneously providing added advantages for their affluent peers. Unless policymakers address the interrelated problems of school district boundaries and housing affordability, millions of families will continue to find themselves priced out of their preferred public school systems. This brief examines the relationships among rental housing access, per-pupil funding, and school district boundaries in the country's 200 largest metropolitan areas by exploring three core questions: (1) How much access do low-income families have to housing in each public school district?; (2) What is the relationship between the accessibility of rental housing in school districts and per-pupil funding?; and (3) How do school district boundaries affect low-income families' access to public schooling options within their broader communities?
