Hudson County's population grew at a faster rate than any other New Jersey county last year, according to new figures from the U.S. Census.

The county saw 0.8 percent population growth between July 2014 and July 2015, slightly above Bergen County's 0.6 percent growth, the figures show. Bergen remains the most populous county in New Jersey, at 938,506 residents as of July 1.

Since 2010, Hudson County's population has boomed, rising from 634,277 to 674,836, according to the Census.

2015 data on populations of towns and cities won't be available until May. It's likely that Jersey City's building boom is largely responsible for the county's increased population.

Since 2010, Jersey City's population grew by 14,549. Mayor Steve Fulop said he thinks it will soon overtake Newark as the state's most populous city. Census figures put Newark's 2014 population at 280,579 to Jersey City's 262,146.

"It's no secret that we have access to great mass transportation, and it's a diverse city," Fulop told The Jersey Journal. "It's a place where people want to live. I would expect those trends are going to continue."

While Jersey City may have added more residents than anywhere else in Hudson County, each of its 12 municipalities is growing. Between 2010 and 2014, Secaucus' population increased by 13 percent, to 18,416.

Secaucus Michael Gonnelli is less enthused about his town's population spike. More residential development, Gonnelli told The Jersey Journal, means an increased strain on town services and the public-school district.

"I'm not that keen on residential" [development], he said.

After Hudson and Bergen counties, Union County grew by 0.5 percent. The statewide population grew by 0.2 percent, bringing the New Jersey population to 8,958,013.

Hudson remains the fourth most populous county in the state, behind Bergen, Middlesex and Essex.
