DENVER - For the 24th straight month, the overall index for the Mountain States region, a leading economic indicator for the three-state area of Colorado, Utah and Wyoming, advanced above growth neutral 50.0. The national index has risen above growth neutral for 26 consecutive months (www.ism.ws) but has remained lower than the regional reading. The gap between the results of the two surveys has widened, primarily as a result of Mountain States' growth tied to the region's large energy sector, exports and agriculture.
