However, during the workday, the city swells to more than 120,000 residents, workers, and visitors, due to the more than 3,600 businesses that are located in the city.

From the North Georgia Mountains to the Chattahoochee River along a Cherokee Indian trail, a tiny village named New Prospect Camp Ground was formed. This village, made up of tents, a log school, and arbor became a trading post where Indians and white settlers exchanged their goods. The surrounding countryside provided excellent farming land, especially for cotton. On December 11, 1858, the town was chartered and became the county seat of Milton County. The town was renamed Alpharetta, a misspelling of Alfarata, a character in a popular period song (The Blue Juniata). Note that this conflicts with the city's version of how the name came about. Alpharetta's city website states the name is a combination of the Greek words for "first" and "town", however "town" in Greek is "Poli" or "Polis" and "Retta" is not even a Greek Word. Officially chartered on December 11 of that year, Alpharetta served as the county seat of Milton County until the end of 1931 when Milton was merged with Fulton County to avoid bankruptcy during the Great Depression.
