Idaho was admitted to the United States in 1890 as the 43rd state.
Idaho is in the northwest region of the U.S. with Washington and Oregon to the west and Montana and Wyoming to the east.
Idaho is the one of the least populated states in the U.S. Boise is the capital and largest city. Idaho's terrain is rugged and mountainous with wild rivers, deep canyons and vast lakes.
Climate in the west is affected by the Pacific Ocean, tempering the cold in the winter and causing above average precipitation. The eastern part of the state is drier with more extreme temperatures.
Agriculture, lumber, wood products and manufacturing, particularly semiconductors, lead Idaho's economy. Taxes in Idaho are higher than average.
