Those millennials are not a part of the study:

The Pew Research Center’s definition of millennials is people born from 1981 to 1996. In 2012, the youngest millennials were still in their teens. In order to exclude those who were likely still in school, the analysis was done only on people who were at least 20 in 2012, i.e. born between 1981 and 1992.
