Reams of research have shown stark achievement gaps between white and Asian students and their black and Hispanic peers. But a new interactive database released Wednesday shows how pervasive the achievement gap is across the city and its roughly 900 elementary schools.

The interactive, created by the New School’s Center for New York City Affairs, shows strong correlations between students’ race and income and their elementary math scores, and also reveals that wide achievement gaps often exist even within individual schools.

The report comes with a few caveats: It is based solely on recent census data (not each family’s actual income) and last year’s math scores for students in grades 3-5, offering just one metric to judge student achievement.

Here are four takeaways the data:

  1. Math scores vary by race and income
  2. Low-income students of color are doubly isolated
  3. Socioeconomically diverse schools tend to have big achievement gaps
  4. Some schools manage to defy that trend such as academy charter schools
