Quincy Population Tops 101,000


Quincy’s population has surpassed 101,000 residents, an increase of more than 10 percent over the past decade, according to recently released federal census figures.

The data also show that Quincy has become more diverse since the last decennial census.

The US Census Bureau on Thursday released results of the 2020 survey that show Quincy’s population had grown to 101,636 residents. That number is up from 92,271 residents in 2010, an increase of 9,365 people or 10.15 percent.

Mayor Thomas Koch said he expects Quincy’s actual population is higher than what the latest census indicates.

“The number that came in, I think, was a little low,” he said in a phone interview Thursday. “We knew we were going to be over 100,000.”

Koch said the Donahue Institute at the University of Massachusetts estimated Quincy’s population to be 106,000 earlier this year. He said city officials were awaiting ward and precinct data to determine whether to appeal the census numbers.

“I just want to make sure the count is as accurate as humanly possible,” Koch said, adding that immigrant populations can be difficult to count.

The mayor said Quincy would now be eligible for new federal and state funding because its population has surpassed 100,000.

The census data indicate that Quincy’s white population decreased from 67.3 percent in 2010 to 54.2 percent in 2020. The city’s Asian population rose from 24 percent in 2010 to 30.7 percent in 2020 and its Black population grew from 4.6 percent to 5.4 percent in that same time frame. The city’s Hispanic or Latino population increased from 3.3 percent in 2010 to 5.1 percent in 2020.

With 101,636 residents, Quincy is now the seventh most populous community in Massachusetts, up from eighth in 2010. Quincy edged out Lynn (101,253 residents) and New Bedford (101,079 residents) for the seventh spot – New Bedford was the state’s seventh most populous community ten years ago.

Only Boston, Worcester, Springfield, Cambridge, Lowell and Brockton have more residents than Quincy among Bay State cities and towns.

The new census figures will be used to draw up precinct and ward lines for local elections and will also be used to establish new federal and state legislative districts. The numbers are also used to determine how federal funds are allocated.

Overall, Massachusetts’ population grew from 6.55 million residents in 2010 to 7.03 million in 2020, an increase of 7.4 percent. The Bay State will continue to have nine seats in the US House of Representatives following the latest round of redistricting.

The Census Bureau has in the past released its community level-data by April 1. It was delayed to August this year, however, because of the COVID-19 pandemic.
