Financial capability is a multi-dimensional concept that encompasses a combination of knowledge, resources, access, and habits. The NFCS is designed to understand and measure a rich, connected set of perceptions, attitudes, experiences, and behaviours across a large, diverse sample in order to provide a comprehensive analysis. As with previous waves, the 2015 NFCS has been updated to include questions on additional topics that are relevant today, such as student loans and medical costs, while maintaining key measures to enable tracking comparisons over time.
