One complexity here may be in how members are treating taxation and tax deductibility in relation to their donations. “income” in your sample is self-reported and it is presumably pre-tax income. However, per GWWC: “While we have defined income as pre-tax in the past, after speaking with members in a variety of situations we believe there should be some flexibility here.
If you expect to receive a tax deduction for your donation, we recommend basing your giving on your pre-tax income.
If you expect to get little or no tax deduction, for example because your country does not offer tax deductions on donations, you may choose to donate based on post-tax income.”
Thus people may be keeping to the terms of their pledge but donating less than 10% of their pre-tax income if they are not getting a tax deduction
I checked and ~22% of GWWC members* did not donate more than 5% of their income in 2017, so even assuming taxes accounted for a large portion of the issue, there are still a lot of people who are not reporting data consistent with keeping the GWWC pledge.
*this analysis was limited to people who (a) took the 2018 EA Survey, (b) reported having taken the GWWC pledge, (c) reported income and donation data, (d) are non-students, (e) have income >$10K, and (f) reported joining GWWC prior to 2017. N=253.
