However, I do have a link to a new study just completed by CARA, Women and Men Entering Religious Life: The Entrance Class of 2016. This is a fascinating and detailed look at those who entered religious life--religious sisters and brothers--in 2016. I am a bit of a nut on hard data and research as opposed to impressions and opinions, so I find these kinds of study very helpful to the ministry. Among other things, this study gives an indication of the kinds of parish and institutional ministries impact individuals to the point of dedicating their entire lives to prayer, community and ministry. Much of this data on local church life is transferable to all parish, educational, and institutional settings in the Church.
A well-written study animates thought and impacts attitude. If you open the link, don't overlook the "raw" responses of participants, pages 59-117. This kind of window on religious life does not come along very often.
