Most people have an idea of what it means to be poor. We think of conditions like hunger, homelessness, preventable diseases, unemployment, and illiteracy as elements of poverty. Those and other issues will be covered later in this book. However, from a social and economic standpoint, poverty is a complex topic that can be difficult to describe in objective terms. Most governments and social service agencies have their own definitions of poverty, including how it is measured and who is considered poor.
