Forbes recently took a look at the nation’s fastest-growing cities and ranked Austin first, for the second year in a row. And it's no wonder, given that city's tech-heavy employment picture and young workforce. In fact, the list was dominated by metros with a strong base of technology companies and universities, such as Raleigh, N.C.; San Jose, Calif.; and Seattle.  

Beyond Austin, Texas has a big presence on the list, represented by metros like Dallas-Fort Worth, Houston and San Antonio. And much of the migration patterns over the last several years are toward lower cost-of-living locales: Seven of the top 10 cities are found in the south.
