This book examines financial vulnerability: a state in which a person or household cannot absorb any substantial spending or negative income shock without substantial financial and ultimately broader harm such as job loss, emotional harm, or mental illness. The focus of the book is on the experiences of low- income and modest income Canadian families ¿ families which, by virtue of being in the lower income brackets, are particularly at risk of experiencing financial hardship. Looking at vulnerability from a conceptual and empirical lens, this book offers a framework to better understand the complex and interdependent ways in which financial vulnerability emerge and can be addressed.
