About this Map

Current Status of Charter Schools in the United States

This map provides reference information on charter schools by state. Clicking on a state icon accesses Information for that state, including:

- The year of charter school legalization, with a link to the enabling legislation;

- The type and number of charter school authorizers;

- A description of the charter school funding mechanism;

- The number of charter schools in operation;

- Charter schools as a percentage of all publicly-funded schools; and

- Charter school students as a percentage of all students attending publicly-funded schools.

State icons also include links for additional information on funding and, for some states, links to helpful Question and Answer (Q&A) or Frequently Asked Question (FAQ) pages. The color gradient represents the percentage of charter schools by state as a percentage of the total number of public schools - a higher color indicates a higher percentage. Arizona and Washington, DC are outliers in the data and are represented in black

The map is a joint project of the Program on Human Rights and the Global Economy (PHRGE) and the NuLawLab, both based at Northeastern University School of Law. PHRGE’s Executive Director, Kevin Murray, conceived the map and Margot de Costerd and Ethan A. Dazelle designed and researched it with the assistance of Jules Rochielle Sievert, Creative Director at NuLawLab.

Margot de Costerd is a junior majoring in history at Smith College in Northampton, MA. Her interests include computer mapping, data visualization, and the use of technology to advance human rights.

Ethan A. Dazelle is a third-year law student pursuing a JD/MBA at University of Massachusetts School of Law. His interests include human rights, foreign policy, and researching enforcement mechanisms in international law.

The Program on Human Rights and the Global Economy (PHRGE) at Northeastern University School of Law was founded in 2005 to engage in study, promotion, implementation and constructive critique of rights-based approaches to economic development and social transformation. PHRGE supports cutting edge human rights scholarship and movement-building, with particular focus on economic, social and cultural rights, and works with students to ensure that human rights perspectives will continue to be vital to future generations of scholars and advocates.

The NuLawLab at Northeastern University School of Law was founded in 2013. It is the nation’s first U.S. law school interdisciplinary innovation laboratory. NuLawLab works to imagine, design, test, and implement pioneering approaches to legal empowerment and data representation.
