This paper examines financial literacy in the United States, using the 2021 National Financial Capability Study data. A large volume of papers have demonstrated the importance of financial knowledge and documented the low level of financial literacy in America. Using recent data collected during an unusual time when inflation was rising and the country was in the midst of the COVID-19 pandemic, we show that the knowledge of fundamental financial concepts continues to be low in the US, especially among people who are young, less educated, female, or not employed. Our analysis also highlights people’s lack of inflation knowledge and identifies the subgroups that are particularly vulnerable. Finally, we examine how financial literacy affects financial well-being and behaviors. Responses to the Big Three financial literacy questions are linked to important financial behaviors and outcomes, including planning for retirement, financial resilience, and not carrying too much debt.
