The cities Hamtramck and Highland Park are enclaves of the City of Detroit. Hamtramck is known for being home to a large Polish community. This is evidenced in many ways, such as the celebration of Pączki pronounced: poonchki Day. In 1970, 91% of the residents were Polish. However, today its only about 22% because many Poles have moved to other parts of the area, and because of a large immigration of people from the Middle East and South Asia.
Highland Park is home to several architecturally significant buildings. It is also home to the Highland Park Ford Plant, the first plant in the world to use the assembly line.
