Crowdfunding is an increasingly popular way to raise emergency funding after disasters. However, for victims of a major Colorado wildfire, we find that crowdfunding raised more support for wealthier beneficiaries rather than helping the most vulnerable. Specifically, beneficiaries with income above $150,000 receive 28% more support on GoFundMe than beneficiaries with income below $75,000. High-income households are also 14 percentage points more likely to have a crowdfunding campaign at all. These findings hold conditional on the amount of property value destroyed by the fire. The regressive allocation of disaster crowdfunding relates to several network advantages possessed by high-income households, including more connections outside the disaster area. Our findings highlight substantial disparities in social network insurance, which, as we show, likely exacerbate income inequalities in the recovery process.
