CT's Population Remarkably Stable for a Century, Data Shows

Connecticut’s nickname as the Land of Steady Habits, is well-earned, as evidenced by a review of population origin during the past century.   Connecticut's domestic migration pattern has been remarkably steady through the decades, and most of the change has been due to immigration, according to data compiled by The New York Times. The hundred year comparison:  In 1900, 57 percent of the state’s residents were born in Connecticut.  A century later, in 2000, a nearly identical 55 percent of the state’s population was born in Connecticut.

The percentage of Connecticut residents born outside the United States was as high as 29 percent in 1910, steadily declined to a low of 10 percent in 1970 and 9 percent in 1980 and 1990, and then began to slowly climb, reaching 11 percent in 2000 and 14 percent in 2012.

The breakdown of Connecticut’s population origins, between 1900 and 2012, as reported in The New York Times, is currently:

• 55 percent born in Connecticut,
• 14 percent born outside the U.S.
• 10 percent born in New York,
• 6 percent born in other states in the Northeast,
• 4 percent born in Massachusetts,
• 4 percent born in states in the South,
• 3 percent born in other U.S. states (excluding the Northeast, South and Midwest),
• 3 percent born in Midwest states,
• 2 percent born in states in the Western U.S.

In 1900 and 2000, four percent of the state’s residents were born in neighboring Massachusetts.

By way of comparison, the percentage of Massachusetts’ population born in the Bay State was 55 percent in 1900 and 63 percent in 2012.  In New Hampshire the percentage of native born was 60 percent in 1900 and 42 percent in 2012 – when one quarter of the population, a robust 25 percent, were born in neighboring Massachusetts.  In Rhode Island, the population was 51 percent native born in 1900 and 57 percent in 2012.  Only 9 percent of Rhode Island’s recent population was born in Massachusetts.

The states with the lowest percentage of their population born in-state are Nevada, 25 percent; Florida, 36 percent; Arizona, 38 percent; Wyoming, 40 percent; and Alaska, 42 percent.

On the opposite end of the spectrum, 79 percent of Louisiana’s population was born in the state; 77 percent of Michigan’s; 75 percent of Ohio’s and 74 percent of Pennsylvania’s.

The largest immigrant population, by percentage?  California at 28 percent, New York at 25 percent, Florida at 23 percent and Nevada at 21 percent.
