San Francisco saw its homeless population rise by 17% in the last two years, but the rise in many surrounding counties has been worse.

A report Monday by Curbed San Francisco summarizing the figures noted: “Five out of nine Bay Area Counties—i.e., all of those not located in the North Bay—saw their homeless counts spike during the same period, with each other county showing worse homelessness surges than SF.”

As Breitbart News has noted, homelessness has been rising rapidly in urban areas throughout the state. San Francisco’s rise in homelessness has been accompanied by a spike in Los Angeles that some say has brought the city to the brink of an outbreak of deadly disease — perhaps bubonic plague. San Diego recently suffered an outbreak of hepatitis A among the homeless, partly due to a plastic bag ban making it harder for homeless people living on the streets to dispose of excrement.

Now the problem is leaving downtown areas and hitting the suburbs. Curbed reports:

San Mateo County: rise of more than 20% in two years

Santa Clara County: rise of more than 31% in two years

Alameda County: rise of more than 42.5% in two years

Contra Costa County: rise of 42.8% in two years

In addition, the San Francisco Chronicle reported Monday that homelessness in the City of Oakland alone rose 47% over the past two years.

The Curbed report adds some “good news”: ‘While the rest of the Bay Area saw the levees break, homelessness actually declined significantly all over the North Bay during the same period.”

President Donald Trump has warned that federal intervention may be necessary to deal with the problem — a suggestion that has met with protest from the state’s Democratic leaders.
