Data are from the IRS SOI Tax Stats County Data. Charities receiving donations may be located anywhere. Individual donations to charity are grouped by tax return, so include both individual and joint filers. Data are limited to those who itemized deductions on their tax returns (45% in 2017, 24% in 2018, 23% in 2019, and 21% in both 2020 and 2021, for Santa Clara and San Mateo counties, combined); however, while only 21% of 2021 returns were itemized, those returns represented 60% of the regional adjusted gross income.

Data include only returns with itemized deductions.
