The 10 healthiest counties in Utah

Wasatch County made strides in this year's healthiest county rankings, knocking Summit and Davis counties down a notch and taking hold of fourth place.

Several other Utah counties shifted slightly in the results of the annual study, released Wednesday by the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute.

Morgan, Cache, Utah, Summit and Davis counties have traditionally held the top five spots, with Carbon, Sevier and Duchesne counties at the bottom. Daggett and Rich counties were not included in the rankings.
