Connecticut is the third smallest state by area, the 29th most populous,[ and the fourth most densely populated of the 50 United States. It is known as the "Constitution State", the "Nutmeg State", the "Provisions State", and the "Land of Steady Habits". It was influential in the development of the federal government of the United States. Much of southern and western Connecticut (along with the majority of the state's population) is part of the New York metropolitan area; three of Connecticut's eight counties are statistically included in the New York City combined statistical area, which is widely referred to as the Tri-State area. Connecticut's center of population is in Cheshire, New Haven County, which is also located within the Tri-State area.
Idaho prior to European settlement was inhabited solely by Native American peoples, some of which still live in the area. In the early 19th century, Idaho was considered part of the Oregon Country, an area disputed between the U.S. and the United Kingdom. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead being included for periods in Oregon Territory and Washington Territory. Idaho was eventually admitted to the Union on July 3, 1890, becoming the 43rd state.
