The "Contiguous United States" refers to the 48 adjoining states located on the North American continent, excluding Alaska and Hawaii. This area stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west, and from Canada in the north to Mexico in the south. It encompasses a diverse range of landscapes, climates, and cultures. The contiguous states are often referred to as the "lower 48" and include major cities like New York City, Los Angeles, and Chicago. This region is significant for its economic activities, population density, and historical development, playing a central role in the overall identity of the United States.
