There are more people who lack domestic situations in California than in any other state. Well, that should be obvious. There are more people in California than in any other state. 12% of all Americans live here. Even if the rate of houselessness were the same here as it is in other states, 12% of those who are houseless in American would live here. That is a significant number!
Since the rate of houselessness here is approximately double that of the rest of America, approximately 24% of those who are houseless in American should reside in California, although the actual ratio is approximately 22%.
This is not because houseless people migrate to California. More of the unhoused live in or near their hometowns than those who live within homes. Although the primary causes of houselessness are similar, albeit to various degrees, for most regions of America, the main difference is the cost of housing.
Homes and rents are ridiculously expensive here. It is extremely difficult for those who lose a home to procure another. If houselessness is the result of unemployment, it is very difficult for someone who lacks a domestic situation to procure new employment in order to procure a new domestic situation!
Recovery from houselessness is not nearly as difficult in other regions, even with significantly less income. Furthermore, since mortgages and rents are more affordable, it is not nearly as difficult to maintain a stable domestic situation in order to avoid becoming houseless. Many who live in poverty here can afford to directly purchase a home in other regions.
Not many houseless people migrate to California. More migrate from California to live in homes elsewhere. Unfortunately, they are replaced by more Californians who become houseless. Many prefer to stay in their respective home regions rather than migrate.
