Recently speaking with my father, the topic of California's unemployment came up. Trying to estimate the number of unemployed (this was before the official statistics came out), he used this formula: say there are about 30 million residents of California. Approximate that about 20 million are of the working age (18-65), and of those, say that about 15 million choose to work. If the unemployment rate is at 10%, this should equate to somewhere around 1.5 million unemployed.
