Cost Of Living Hi-Lo Difference Within Individual States

From Pew Reseach Center, "The real value of a $15 minimum wage depends on where you live" by Drew DeSilver:

Living costs not only vary widely throughout the country, they can vary a lot within individual states as well. In California, the priciest metro area (San Jose-Sunnyvale-Santa Clara, more or less synonymous with Silicon Valley) is 42.3% more expensive than the least costly (El Centro, in the Imperial Valley across the border from Mexicali, Mexico). Metropolitan Miami is 30.3% more expensive than Sebring, Florida, roughly three hours to the northwest.
