The "Segregation—Measurement, Causes, and Effects" conference brought together experts in economics, sociology, and geography to discuss the forms, measurement, and impact of segregation. Some researchers at the conference presented theoretical work on different concepts of “segregation” and their associated measurement strategies. Others discussed empirical work on the evolution and effects of school, housing, and income segregation. Cross-field dialog was central, enabling all attendees to learn about each others’ methods, findings, and open questions.
