About half a million people in Connecticut were born in another country.
Caribbean and South Americans are the biggest group of immigrants in Connecticut, accounting for about 150,000 of foreign-born residents. In addition, 55,000 Central Americans and 13,000 Canadians found their way to the Constitution State.
But this data, from the 2013 American Community Survey, shows that these large pockets of Latin Americans often live in the cities, while there is a halo of surrounding suburbs populated by Asian immigrants.
For example, Latin Americans account for a large proportion of the foreign-born population in New Haven — largely Mexicans, Jamaicans and Ecuadorians. But outside New Haven, West Haven and East Haven, and the foreign-born population hails from Asia — mostly China and India.
This same phenomenon can be seen a bit north, where the dominant foreign-born population in Hartford, East Hartford, Windsor and Bloomfield are Latin Americans — but, just outside in several surrounding suburbs, Asians are the largest group. This also occurs in and around New London.
The rest of the state’s foreign-born population hails mostly from Europe, but be careful about making any real conclusions in small towns in Connecticut. Foreign-born populations in small towns, such as Essex, are small enough that the margins of error render the data fairly meaningless.
When did they come to the U.S.?
The majority of foreign-born residents arrived in the U.S. before 1990 — about 40 percent. But in many cities, like Hartford and Stamford, the 2000s saw a boost in the arrival of foreign-born residents. (Click on your town below to see when the foreign-born population arrived.

What country are they from?
The clusters of Latin Americans, Asians and Europeans aren’t homogenous. Going back to the New Haven area, the city’s dominant foreign-born population is Mexican, and the same goes for West Haven. But in East Haven, Italians are the dominant population. In nearby suburbs, dominant foreign-born populations include Chinese, British, Polish and English.
Accurately counting the dominant immigrant populations is difficult in many Connecticut towns, because the sample sizes are just too small. But it is possible to see small pockets of homogenous ethnic groups in some areas.
For example, in and around Hartford, the dominant foreign-born population are Jamaicans. Southwest of Hartford, the Polish are the dominant foreign-born population. And to the east of Hartford, immigrants from India are the dominant population.
Be careful, however, when looking at this map, because the margins of error may be quite large. We did not color towns with margins that are extremely big.
