Following the Second World War Shaler became an affluent suburb with many former City of Pittsburgh residents now populating the Township. Shaler, along with Ross Township, was among the first outer-city areas to develop into the modern suburbs which today define the North Hills region of Allegheny County. Home building and development during this time period was extensive. Shaler remained and still remains a primarily residential municipality, and it was during this period which the Township came to acquire the attributes it still holds today.
