When then-Bishop Dolan was named Archbishop of Milwaukee, the number of Catholics here was reported as "about 700,000".
The recent New York Times report of his designation as a Cardinal includes his recounting of the 2004 ad limina visit to Rome. "I said: ‘Holy Father, we have good news. The Archdiocese of Milwaukee is growing.’”
That same article gives the number of Catholics in our Archdiocese as 630,000.
