- About Segregation
Racial residential segregation remains one of the root causes of racial inequality in the United States, but the problem does not receive the public attention it deserves. Measuring segregation is difficult and data-intensive. We aim to make this as easy as possible by providing you complete calculations for six different measures of segregation.

Every census tract in the United States is labeled as higher, moderate, or low segregation for each index. Furthermore, you can run your cursor over a tract to see both it's index score and it's demographic profile. In addition, you can click the 'show change over decades' button to see how segregation has changed for that tract over time, examining changes between any two points from 1980 to 2010.
