Not so....bad math work.  Your numbers assume that all priests beginning in 1950 served 30 years forward in time...but of course that's ludicrous.  Priests were retiring in 1950, and every successive year after, being replaced, plus or minus.

There are just short of 100 parishes in Sante Fe.  

You also assume once a priest is in Sante Fe...no one leaves the archdiocese..and no one comes in mid-vocation.  

Show you work where you also counted for the "religious priests" coming and going into the archdiocese; few of these do whole careers in the archdiocese. 

Santa Fe is a wonderful place to retire (one of the best in the countries)....priests retire too...and they often serve for free there.  Did you account for those?  

Show your work. 

Fix your assumption..and you'll get between 1 and 2 thousands.

Thanks.
