Lyme saw a 15.1 percent increase in its median home values, the second-highest in the state. North Stonington saw a 15.8 percent decrease in the percent of the population with a bachelor's degree or higher, the fifth-greatest decrease in the state. New London has the fourth lowest median age, at 31.

These are some of the anomalous local takeaways from looking at CTData Collaborative's interactive map comparing American Community Survey five-year estimates for 2018 with those from 2013.

The American Community Survey is a program of the U.S. Census Bureau, which released its 2014-18 estimates last week. The survey is used, the Census Bureau notes, in decisions on where to locate schools and what goods businesses should provide to customers.

Every year, the Census Bureau contacts more than 3.5 million households nationwide to participate, and it gathers demographic, social, economic and housing data.

The United States, Connecticut and New London County each saw increases in the percentage of housing units that are renter-occupied and decreases in the percentage of owner-occupied residences; the percentage of housing units with no vehicles available declined in all three locations.

The population of veterans dropped from 9 to 7.5 percent nationwide, 7.9 to 6.2 percent in Connecticut, and 12.1 to 10.5 percent in New London County.

Among women who gave birth in the past 12 months, the percentage who are unmarried decreased nationwide and in Connecticut but increased from 32.3 to 38.9 percent in New London County.

The total Connecticut population decreased by 0.05 percent — about 2,000 people — while the U.S. population increased by 3.6 percent. Lyme was the only town in New London County to see population growth; the estimates increased from 2,417 to 2,469.

Here are five other takeaways, from both the CTData Collaborative's map, which The Hartford Courant previously reported on, and The Day's own review of some of the data.

The overall population is getting older

The CTData Collaborative noted that the median age — the one in the middle, if the ages of everybody were lined up in order — of the state's population increased from 40.2 to 40.8. The median age in the country overall increased from 37.3 to 37.9.

Only 31 of the 169 towns in Connecticut saw the median age drop, and only four of those had a decrease of more than two years. One of those is Ledyard, where the median age dropped from 42.2 to 39.1.

The population is getting more educated

In Connecticut, the share of people over age 25 with a bachelor's degree or more rose from 36.5 to 38.9 percent, while the national increase was from 28.8 to 31.5 percent.

In southeastern Connecticut, the largest growth in the number of people with bachelor's degrees from 2013 to 2018 was in Ledyard and Bozrah, with respective growth rates of 20 percent and 30.8 percent.

Connecticut home values are down

The median home value in Connecticut decreased by 2.2 percent to $272,700, the CTData Collaborative noted, while nationwide, values increased from $176,700 to $204,900.

In New London County, the only towns to see rising home values were Lyme, up 15.1 percent, and Sprague, up 5.5 percent.

Uninsured rates have gone down

Nationwide, the share of the civilian, non-institutionalized population that is uninsured declined from 14.9 to 9.4 percent. This figure went from 5.5 to 5.3 percent in Connecticut, and from 7.4 to 4.3 percent in New London County.

Commutes continue to get longer

The average commute to work increased from 25.5 to 26.6 minutes across the country, from 26.4 to 26.8 minutes in Connecticut, and from 22.8 to 23.5 minutes in New London County.
