A study on the 4,000 international religious sisters serving in the United States was presented in Rome at a meeting of the International Union of Superiors General.

The study, conducted by Trinity Washington University and the Center for Applied Research in the Apostolate, found that sisters from at least 83 countries are serving in the United States and that they arrived, on average, at age 30.

One-third come from Asia, 28% from Europe, 27% from elsewhere in the Americas, and 10% from Africa. Approximately 60% entered religious life before coming to the United States.
