The Fragile Families Challenge: A Scientific Mass Collaboration to Improve the Lives of Disadvantaged Children in the United States

In 2017, a team of researchers affiliated with Princeton University hosted a scientific mass collaboration, which used predictive modeling techniques to predict a set of six outcome variables at children's fifteenth birthdays based on data from the first five waves of the Fragile Families and Child Wellbeing Study. Participants were provided with a special merged version of the study data to be used to develop their models during the collaboration. These Fragile Families Challenge files contain their own unique identifier for each family in the study, and were constructed specifically for use during this project. These files should be downloaded in order to extend or replicate the work from the Fragile Families Challenge, but should not be merged with the Fragile Families and Child Wellbeing Study data files for new analyses.
