The population was 1,787 at the 2020 census. The village of Butler exists due to the railroad. It began in the season of fall in 1909, when people from the Milwaukee, Sparta, and North Western Railway visited farmers living on the eastern area of 124th Street and bought their land to start railroad yards around the City of Milwaukee to relieve congestion in the downtown rail yards. These railroad yards were called "New Butler". Butler was probably named for William Butler, a large property owner in the area who had emigrated from England in the mid-1840s. In 1911, the settlement of "New Butler" was started within Waukesha County, Wisconsin. This community was started by railroad workers and their families and was incorporated with 200 people on May 5, 1913, from what land that was previously parts of the towns of Brookfield and Menomonee. The village grew as more railroad activities started, and allowed real estate speculators to buy parcels of additional land for development. In 1926 the "New" was removed from the name of the village.
