A reader by the name of Woodlawn has kindly provided some information about locations in the USA where Mass in the usus antiquior is offered daily. It is as follows:
FSSP 38,
SSPX 31,
ICRSS 13,
Other 24,
Total 106 or 75 if SSPX is excluded.
Other includes both Diocesan churches and chapels, and the houses of religious communities. In England and Wales, Daily Mass in the usus antiquior is only offered in a few locations. I can only think of Reading (FSSP), New Brighton (ICKSP), Brompton Oratory (Oratorians), St Dominic's Dursley (Diocesan), Clapham Park (Diocesan)and Leicester (Dominicans). Of course, Preston (ICKSP) will soon be added.
This is another illustration of how much the traditional movement has advanced in America, compared with England and Wales.
