Two military installationsGowen Field, in Boise City, and the Orchard Combat Training Center, located in unincorporated Ada County, play an important role in the overall health of the regional economy. The role of agriculture and food processing is also signicant. Ada County has the fourth highest number of operating farms in the state and agriculture and food processing jobs span several industries, such as manufacturing and transportation. In addition, food producers are increasingly seeking to locate near where the agricultural products they process are grown and in some instances these uses are better suited to more rural locations like unincorporated Ada County. Companies such as J.R. Simplot and PowerBar have facilities in Ada County and other companies have facilities in nearby Canyon County.6AgricultureTotal and Per Farm Overview, 2017 and change since 20122017 % change since 2012Number of farms 1,304 +6Land in farms (acres) 112,370 -22Average size of farm (acres) 86 -26Percent of county land in farms 16.6%FIGURE 7.
