In 1910, Highland Park, then a village, had 4,120 residents. Between 1910 and 1920 during the boom associated with the automobile industry, Highland Park's population grew to about 46,500, an increase of 1,081 percent, reaching its peak around 1927. The growth of Highland Park and neighboring Hamtramck broke records for increases of population; both municipalities withstood annexation efforts from Detroit. In 1925, Chrysler Corporation was founded in Highland Park. It purchased the city's Brush-Maxwell plant, which would eventually expand to 150 acres and serve as the site of the company's headquarters for the next 70 years.
