There are usually two collections each Sunday.

I have never been to a Catholic Church that has two collections every Sunday. Second collections are only a few times a year for specific purposes usually dictated by the Bishops or Rome. Sometimes there is a second collection for a specific parish purpose but this is not regular or usual.

In every parish I’ve attended in the four dioceses I’ve lived in, two collections were taken every Sunday. The first for the parish, the second for some other charitable purpose. About 8 Sundays a year we have a special visitor raising funds for a specific mission project, not to mention the collections for our vicariate schools, our diocesan seminary each quarter, etc.

This is true. We will see second collections from time to time, but not every Sunday. My parish will also have a second collection every 2 or 3 months for debt reduction, but other parishes may differ.

Neither have I, and I've lived in five different states. Second collections are taken up, at most, once a month, again, as you said, unless the Parish is raising funds for the Parish School, CCD program, Youth Ministry,etc. and that's only once or twice a year.
