Interstate 8 enters Arizona through the city of Yuma. The largest city in Yuma County, Yuma is a popular winter getaway for snowbirds and thrives due to its proximity to the international border with Mexico. As of the 2000 Census, the population of Yuma was 77,515 people, and by the 2020 Census that number grew to 95,548. This does not include winter residents, which bring in hundreds of millions of additional dollars to the local economy.

Yuma has gone by other names in its history: from 1854 until 1858, Yuma was known as Colorado City and from 1858 until 1873, Yuma was known as Arizona City. In 1873, Yuma received its current name, which is in honor of the Native American inhabitants from this region. Incorporation occurred three times in Yuma's history: as a village on July 11, 1876; as a town on April 6, 1902; and as a city on April 7, 1914. Yuma sits at 138 feet above sea level, receives only 2.94 inches of rainfall annually. The average year-round high temperature is over 87 degrees.1
