I would like to offer the following statistics instead:
22.61% contribute nothing
14.19% contribute up to $100
30.20% contribute up to $500
17.27% contribute up to $1000
9% contribute up to $2000
7.43% contribute more than $2000
I hope you will find these statistics informative and helpful.
I do. For example, over 77% of parish households contribute something using the envelopes. (Some of the 22.61% with no recorded contributions might be putting cash in the collection at Mass.) It does suggest some additional statistics that could be of interest. For example, what's the correlation between frequency of Sunday Mass attendance and amounts given?
