"Nearly 30 million households have no bank account or have one but also use alternate financial services at least occasionally, according to the FDIC report. The survey, the FDIC's first in-depth study of the issue, was conducted by the Census Bureau.
The problem is most acute among minorities: 53% of African-American households and 43% of Hispanic households use check cashers or similar services instead of or in addition to banks."
Big numbers. I am surprised but would like to see the breakdown along monetary lines and not racial.
