Professor Caron also notes:

Independent Sector reports that 89% of American households contribute to charity, with an average contribution of $1,620 -- 3.1% of income.

IRS statistics reveal that the average taxpayer with AGI over $200,000 makes over $20,000 of charitable contributions:

• $15,000-$30,000 AGI: $1,916 average charitable deduction
• $30,000-$50,000 AGI: $2,158 average charitable deduction
• $50,000-$100,000 AGI: $2,703 average charitable deduction
• $100,000-$200,000 AGI: $4,057 average charitable deduction
• $200,000 or more of AGI: $20,434 average charitable deduction
