A minimum wage of $10.10 would mean earning about $21,000 per year.
Q: How many Americans work for minimum wage?
A: About 1.6 million, according to the U.S. Bureau of Labor Statistics. They are a smaller share of the workforce than in previous decades.
Another 2 million people are paid even less, because of various exceptions in the law. Many are waiters, bellhops and others whose wages are augmented by tips from customers. Their minimum is lower — $2.13 an hour — and hasn't gone up for more than two decades. Obama supports boosting the minimum for tipped workers to $7.07.
Together, both groups make up 4.7 percent of workers paid by the hour, and even less of the workforce when salaried workers are included.
Q: Are these the only workers who would get a boost from Obama's plan?
A: No. Millions more people who earn less than $10.10 an hour would get an automatic raise. Many of them work in states that have imposed a minimum wage that's higher than the current federal one.
And some people who already make more than $10.10 would get raises, too, as businesses adjusted their pay scales upward.
Democratic lawmakers pushing for the increase predict it would lead to raises for some 30 million people. Republican opponents counter that it could force companies to reduce hiring or even lay off some workers.
