I agree. All too often, the default definition of a parishioner is a married person, whether male or female.  All too often, widows and widowers, the divorced (even if not unlawfully remarried) or simply those who chose to stay single, are invisible or ignored. Having been single for many years after my first marriage was annulled and now single again as a widow, that has been my experience in the several parishes in which I have been a member over the years.
