HCRC researchers are partnering with Northwestern University on a new phase of the seminal Chicago Longitudinal Study (CLS). Since 1985, the CLS has tracked the development of a group of 1,539 individuals who grew up in urban poverty. Intervention group members attended the Child-Parent Centers (CPC) beginning in preschool and continued participation through 2nd or 3rd grade. The new phase of CLS research, which began in spring 2017, further examines the connection between CPC participation, educational attainment, and physical and mental health outcomes at age 37-39.
