This study, now in its fifth decade, follows the lives of 1037 babies born between April 1, 1972 and March 31, 1973 in Dunedin, New Zealand. The multidisciplinary study produces a wealth of information on many aspects of human health and development.
This study, now in its third decade, follows the lives of 2232 twins born in 1994-95 in England and Wales. The study builds knowledge about how environmental and genetic factors shape behaviors, attitudes and health.
The Center for Open Science suggests that all study plans be registered in advance (see point 5 here).
