Connecticut Population 2016

3,587,010

Our 2016 estimate for Connecticut's population is 3,587,010. This figure is based on the 2015 official estimates released by the US Census, and the current rate of decline.

The last confirmed population data for Connecticut was recorded during the 2010 Census, which revealed that the state had a total population of 3,574,097. The latest Census Bureau estimate took that number to 3,590,886, which makes Connecticut the 29th largest state in the United States.

Over the past couple years, Connecticut has actually started to decline in population, currently losing .11% of its population per year. This makes the state one of just 7 that is declining in 2016.

Connecticut Population Density and Demographics

The population density of Connecticut makes for some very interesting reading. Connecticut has a very small land mass -- just 5,543 square miles (14,357 square kilometers) making this only the 48th largest state in the Union by size.

However, Connecticut crams a significant number of citizens into its surface area. The terrain is very flat, and very few areas of the state are inhospitable. As a result, there are an impressive 738.1 people for every square mile (285 per square kilometer), and this ranks Connecticut at 4th place in terms of population density.

Connecticut Population History

Because of its location on the East Coast, many of the early settlers would have set up home in Connecticut - something that is clear from the early population figures.

In 1790, the population of Connecticut was recorded as 237,946, which ranked it 8th among the 16 states recorded in the 1790 census.

From this point, the population within the state grew but at a slower rate than in many other parts of the country. By 1800, the numbers had grown by just 5.5% to 251,002, and similar rises were recorded throughout the first half of the 19th century.

In the latter half of the 1800s, however, numbers were on the rise by significant margins and increases of 20% on a census by census basis were common. By 1900, the Connecticut population exceeded one million for the first time.

The greatest decade of growth for Connecticut was the 1960s, where the population grew at 2.36% annually. This pushed the state over 3 million by 1970. Since 1970, the state's population has continued to grow at a fairly steady rate, to the nearly 3.6 million estimated today.

In 2005, natural growth figures were released and they showed that in the five years since the previous census in 2000, there was an increase in numbers of 67,427. This was calculated based on 222,222 births in the five year period minus 154,795 deaths and a net migration figure of 41,718.

Connecticut Population Projections

Predictions about the future of Connecticut are varied. The last official figure from the 2010 Census and estimates from July 2015 show a 0.5% growth rate. If Connecticut continues to grow these rates, it is estimated that the population will exceed 3.7 million in 2020, and approach 3.75 million by 2025.

On the other hand, others are predicting a continuation of the decline since 2014. The decline is mostly driven by domestic out-migration to New York and Massachusetts, with reasons ranging from high taxes to challenging winters and a worsening real estate market.
