The US governmental public health system, which includes federal, state, and local agencies, is seen by many observers as having a money problem, stemming from a lack of resources. During the COVID-19 pandemic, this lack of resources has had unfortunate consequences for the communities that public health practice leaders are expected to protect. Yet the money problem is complex and involves understanding the nature of chronic public health underinvestment, identifying what money is spent in public health and what the country gets for it, and determining how much money is needed to do the work of public health in the future. This Commentary elucidates each of these issues and provides recommendations for making public health services more financially sustainable and accountable. Well-functioning public health systems require adequate funding, but a modernized public health financial data system is also key to the systems' success. There is a great need for standardization and accountability in public health finance, along with incentives and the generation of research evidence demonstrating the value of and most effective delivery for a baseline of public health services that every community should expect.
