The Survey of American Family Finances was a project of the Pew Charitable Trusts' economic mobility project and financial security and mobility project, with funding from the W.K. Kellogg Foundation. It was administered in 2 waves during 2014 and 2015 to a nationally representative sample of adults who are the financial decision makers in their households by GfK's KnowledgePanel. The survey measures details of family finances, including assets, income, expenditures, and debt. Pew used the survey to study the impact of financial shocks, educational debt, housing costs, and the racial wealth gap - among other factors - on financial security. Demographic data, such as race and citizenship, was also collected.
