SALT LAKE CITY -- New census numbers show Utah County is home to 11 of Utah's 12 fastest-growing cities, and the one exception is a city nearby.
University of Utah research economist Pam Perlich calls Utah County the epicenter of the state's growth.
While Utah's fastest-growing municipality is Heber City in Wasatch County, Utah County includes the next 11 cities on the list. Those are Saratoga Springs, Spanish Fork, Highland, Eagle Mountain, Springville, Pleasant Grove, Lehi, Lindon, Payson, American Fork and Orem.
Provo ranks 15th on the list.
State demographer Juliette Tennert tells The Salt Lake Tribune (http://bit.ly/MB2k9w ) most of Utah's post-recession growth comes from births as opposed to immigration. She says it's no surprise the most growth is coming from Utah County, where the fertility rate is highest.
