Studying twins allows us to better learn about the causes of children’s life outcomes — we can figure out how children may be affected by their genetics and their environments.

In a collaboration between the University of Illinois at Urbana-Champaign and Northwestern University, we are now recruiting families of twins and multiples in Illinois to participate in the Illinois Twin Project. The Illinois Twin Project is an effort to compile a list of parents of twins (identical and fraternal) and other multiples (triplets, etc.) who might be willing to have their children participate in future twin studies.
