Over all, the national rate of homelessness rose by a modest 0.3 percent to 552,830 people without stable living conditions, the report found. But that represented the second annual increase after seven straight years of declines — the result, in part, of rapidly increasing housing costs that have only recently shown signs of leveling off.
