Comparing New London County to the other seven Connecticut counties from 2009 to 2015, growth in median income was the highest in the state for women and lowest for men, according to a study released last month.

It also shows that for both men and women, the parts of the county that saw the highest income growth are in Groton.

The analytics company Pansop compiled estimates from the U.S. Census Bureau to examine changes in income for men and women in every county in the country.

Part of the rationale for compiling this information was to take a "slightly different angle," Pansop data analyst Kevin Pryor said, considering "there's not too much talk about the increasing rate in the news, as much as there is about the difference in pay."

The 2009 and 2015 figures come from the Census Bureau topic called "Median income in the past 12 months by sex by work experience in the past 12 months for the population 15 years and over with income."

Pryor acknowledged that the information is "pretty generic" and "it's hard to ascertain what's exactly happening," considering there are many factors in the gender pay gap, such as choice of profession, hiring bias and pay decisions.

The estimates show that median male income in New London County decreased from $41,899 in 2009 to $41,185 in 2015, or a growth rank of 2,477 out of the 3,129 counties and county equivalents Pansop examined.

Median female income in the county increased from $23,392 to $25,496 during that time, placing it at 1,970 for growth in the country.

Across Connecticut, median income increased 0.3 percent from 2009 to 2015 for men, and 6.5 percent for women.

Mark Hill, chief operating officer of the Eastern CT Workforce Investment Board, noted that there was a shrinking labor force in the region between 2009 and 2015, and that New London County was "five years delayed in terms of our job recovery over the rest of the state."

One of his main takeaways from looking at the data was that the places seeing the highest upward momentum are the places right around Electric Boat.

Pansop pulled out data for 16 cities, boroughs and census-designated places in New London County. This breakdown shows that for men, four of the five places that saw the largest growth in median income are in Groton: Long Hill, 26.7 percent; Groton Long Point, 23.1 percent; Groton City, 18.8 percent, and Poquonnock Bridge, 14.5 percent.

Among women, the largest gains from 2009 to 2015 were seen in Poquonnock Bridge, 70.5 percent; Noank, 34.4 percent; Long Hill, 29.5 percent; Conning Towers Nautilus Park, 20.7 percent, and Old Mystic, 19 percent.

Among the 16 places, income in 2015 was highest for both men and women in Groton Long Point, and lowest in New London.

Hill said that because of EB's growth, he'd be curious to see income figures for 2016 and 2017. The Census Bureau has income estimates for New London County for 2016, but the estimates for the individual cities, boroughs and census-designated places only extend through 2015.

Pansop is a newer site of the 10-year-old company Gridlex, which has 20 employees in New York and India. Pryor explained that Pansop is largely funded through the Gridlex site Dexur, which sells analyses of health care data to medical organizations.

The data for this study was compiled by a data analytics team at Pansop, but Pryor said the long-term goal is for the site to be a community-edited database.
