Economy Of Connecticut

Connecticut has been a global leader in industrial development since colonial times. When it was still a colony, Connecticut’s industries were crucial enough to attract complaints from other competitors in England. Just like all the other parts of the northeastern U.S., Connecticut lost a huge percentage of its industries in the 1940s and 1950s to the Sunbelt region. Connecticut experienced an economic rebound during the 1970s and 1980s. Since then, this state has been ranked as one of the top states in the U.S. in terms of personal income-per-capita. Connecticut’s GDP increased from $225.4billion (2011) to $229.3billion in 2012. Connecticut had the highest per-capita personal income in the country of $60,847 in 2013.

Connecticut has the third-highest number of millionaires-per-capita in the country. The unemployment rate of Connecticut was 3.6% in September 2019.
