People who are homeless are not a distinct and separate population

People who are homeless are not a distinct and separate population. In fact the line between being homeless and not being homeless is quite fluid. In general, the pathways into and out of homelessness are neither linear nor uniform. Individuals and families who wind up homeless may not share much in common with each other, aside from the fact that they are extremely vulnerable, and lack adequate housing and income and the necessary supports to ensure they stay housed. The causes of homelessness reflect an intricate interplay between structural factors, systems failures and individual circumstances. Homelessness is usually the result of the cumulative impact of a number of factors, rather than a single cause.
Structural factors are economic and societal issues that affect opportunities and social environments for individuals. Key factors can include the lack of adequate income, access to affordable housing and health supports and/or the experience of discrimination. Shifts in the economy both nationally and locally can create challenges for people to earn an adequate income, pay for food and for housing.
