Thirty states have explicit policies in place detailing how a community can secede from its current district, and most of those processes have no consideration for the needs of the students left behind. These laws, paired with school finance systems heighten the importance of local wealth, pave the way for gerrymandering that advantages the wealthy and deprives our neediest students of educational opportunities.

The inherent links between race and class in our country haven’t been remedied by school-funding lawsuits nor the passage of time. They remain ever present, and while we have made some progress on the issue of economic inequality in our schools, we still have a terribly inequitable system. For students of color, the problem is even worse. The concentration of low-wealth communities into partitioned communities is even more pronounced for communities of color due to the history of racial segregation in our country, both formal and informal. The ability of local districts to raise revenue for their schools is thus undermined. And political power in the state capitol is diffused and diminished, because there are six times more white districts representing their interests in state capitols than nonwhite districts.

The end result is fewer local resources and less state aid to compensate for it. And so, fifty years after Serrano v Priest, and despite decades of lawsuits throughout the country, there remains a $23 billion gap between white and nonwhite school districts, even though they serve the same number of children.

This interactive map provides a district-level visualization of financial and demographic data for most US school districts in years 2013–16. The data include poverty rates, per-pupil finances (adjusted for cost of living), income, property value, and racial composition. Taken together, the data in this tool help describe the wide gulfs in wealth and privilege that exist both across our nation and between our communities.

School district borders define both which students will be served by a district and where those schools get their dollars. When states rely on local taxes to support schools, borders can be drawn to provide a deep well of resources for all of the community's children—or they can segregate those children along lines of opportunity and wealth.

When shifting conditions leave a school district without enough local resources to get by, it may seek to improve its financial health by consolidating with a better-off neighbor district. But in most states, that's all but impossible. In thirty-nine states, consolidation is purely voluntary, and struggling districts are likely to be turned away by their wealthier neighbor districts. In twenty-five states, there are financial incentives meant to encourage mergers, but they are rarely successful at bringing about consolidations for the districts that truly need them. In fact, only nine states have mechanisms that allow the state to mandate a merger, even in the direst of circumstances.

Income-based segregation between school districts is rising. Today, high-poverty school districts enroll half of America's schoolchildren. Often these high poverty districts neighbor wealthier school systems where children have access to greater resources. Because property taxes play such an important role in school funding, affluent communities have an incentive to establish school district borders around their neighborhoods in order to ensure that the benefit of their wealth is reserved for their children alone. When the families with means isolate themselves in wealthy districts, low-income children are left behind and income segregation between school districts increases.

This report presents the results of EdBuild’s analysis of the degree of income segregation across America's school district borders. In particular, it highlights trends among the 50 most segregating borders, and tells the stories of Detroit, MI; Birmingham, AL; Clairton, PA; Dayton, OH; and Balsz, AZ, whose borders with wealthy neighboring districts are the most segregated in the country.

Schools have the potential to serve as a corrective, a way to bring students of different socioeconomic backgrounds together and to bring resources and opportunity into the lives of needy kids. The school funding system we have, though, only draws brighter lines between the haves and have-nots.

FundED is the first interactive web tool to aggregate and standardize information regarding each state’s education funding laws. The intent of this site is to enable better state-to-state comparisons and provide easy access to detailed information related to the funding policies of all 50 states.

FundED provides information related to the most common elements of state funding formulas through national maps and state pages, organized by the general categories below. Explore the tool using the navigation bar above to see at-a-glance national maps, detailed state comparisons, and downloadable reports.

The Los Angeles Times recently covered an EdBuild report about the California State Lottery, which is presented to the public as a means of generating funding for public education. What the program actually amounts to, however, after all the costs and winnings are siphoned away, is a transfer of $449 million out of the state's poorest communities and into schools in better-off areas.

We often hear this phrase in public education: “How much money we spend on education doesn’t matter; it’s how we’re spending it that’s important.”

While it’s true that our national average funding per student has increased significantly, what matters much more is the picture when we zoom in: who’s making the investment, who receives the funding, and which students need it most?

The state of California, like many others across the country, runs a lottery whose stated purpose is to increase funding for education. In practice, this government-run program results in a transfer of wealth of $449 million from lower-income to higher-income school districts. In California, poor neighborhoods pay much more into the lottery than their schools get out of it, while affluent areas contribute far less than their schools receive.

There’s a new blog post floating around attacking EdBuild that blatantly (and bizarrely) mischaracterizes what we’re up to. It touches on some important policy areas, so it’s worth correcting the facts.

In 2013, there were 26.3 million students living in high-poverty school districts throughout the United States. This is an increase of 60% since 2007. Launch the map to see how we got here.

Recently, EdBuild launched an interactive map that highlights student poverty in every school district across the United States. After receiving a number of inquiries about our methods, we created this guide to help answer common questions.

Schools have the potential to serve as a corrective, a way to bring students of different socioeconomic backgrounds together and to bring resources and opportunity into the lives of needy kids. The school funding system we have, though, only draws brighter lines between the haves and have-nots.
