I’d be interested in a chart similar to “Proportion of GWWC Pledgers who record any donations by Pledge year (per cohort)”, but with 4 versions (median / average donation in $) x (inclusive / exclusive of those that didn’t record data, assuming no record is $0). From the data it seems that both things are true: “most people give less over time and stop giving” and “on average, pledge donations increase over time”, driven entirely by ~5-10% of extremely wealthy donors that increase their pledge.
