Why are Religious Orders in the U.S. dying?
Some are dying and others are growing.
For example, among the Religious Sisters, a number of active communities are dying while others are growing.
Let’s look at the women:
After Vatican II, a number of active communities of Religious Sisters decided to stop wearing their habits (not all but some of the active communities - not monastic ones)
Also, some of the active communities were established to very specific jobs, which after Vatican II were opened up to lay people.
For example: teaching in Catholic Schools, being missionaries to the poor, running nursing homes, etc.
Before & after Vatican II, some of the special missions these sisters had stopped being unique to Religious Life. Often, these sisters had a hard time (due to their Charismas) changing the focus of their orders to remain relevant.
Plus, I think today, when most young women decide they want to be a religious sister, they prefer the whole package … meaning if they are going to be a sister, they want to look the part.
The orders that wear habits (in general) are growing, while the orders that do not (in general) are dying.
As far as the men are concerned, the ones that faithful to Catholic teaching (like the Marian Fathers of the Immaculate Conception) are growing, while groups that have become less faithful are shrinking.
But think the major issue in the USA is that the religious groups (male & female) which are shrinking are typically larger & older orders founded in the 1800s, while the ones that are growing are typically newer & smaller ones founded in the 20th & 21st centuries.
