The Census Bureau reports the population of the Capital City is spread out and relatively young. While more than half of the population is under the age of 18, it is nearly half as old as that. Forty-one percent of people in the city are between the ages of 25 and 44, while another twenty-five percent is sixty-four and above. The median age of the city is thirty-six years, with eighty-nine males for every one hundred females.
Historically, the city was the capital of a territory and then was incorporated into the state in 1866. Its population has been increasing ever since. By the turn of the century, the city had more than five thousand residents, and the Women's Club and Country Club were founded in the city. In 1890, the city was home to the world's largest genealogical library, the Salt Lake City Family History Library, which is open to the public. Interestingly, Montpelier became the capital of Vermont in 1805 and has the least population of any state capital, at only seven thousand. However, the neighboring city of Burlington has over forty thousand residents.
Historically, the Capitol Hill neighborhood was a fashionable residential area until the turn of the century. By that time, wealthy residents began to move south and east, to the country club neighborhood and Cheesman Park area. In fact, Capitol Hill became a very low density neighborhood for single-family homes. Today, more than 80 percent of the city's single-family dwellings are in apartment buildings.
