Well I can say that in my own MO community, in the Riverdale section of the Bronx, all the MO shuls were packed every Shabbat until the shutdown. Young couples with small children have created a massive problem as the shuls do not have enough space to park all the strollers.
I heard one little old lady at a shul board meeting once say that we need to take the eruv down so that the women and small children would stay at home on Shabbat, solving both the space problems, but she was ignored.
