13. Florence-Graham, California

With the cost of living over a third over the national average, and the typical household yearly earning just a little above half of the state’s median, about 21,000 of Florence-Graham’s 63,000 residents live below the poverty threshold, making it very difficult for them to enjoy the basics in life. This could be explained by the lack of higher education among its workforce, limiting them to low-paying jobs as only 4 out of every 100 able-bodied adults have bachelor’s degrees.
