Quincy Demographics
A Portrait of Quincy
Walk through North Quincy or Wollaston and you will hear Cantonese, Mandarin, and Vietnamese on the same block. Quincy is the largest city on the South Shore and one of the most diverse in the region: nearly a third of residents were born outside the United States, and close to three in ten are of Asian descent, the legacy of decades of immigration. Figures below are from the U.S. Census Bureau and the Secretary of the Commonwealth. Follow the source links for the latest.
