These projections are created based upon several datasets and while these estimates are developed based on multiple data sources, actual population changes may vary from these projections. To assist in planning, analysis, and decision making, the population projections have been developed based on state and locally derived fertility rates.

About this dataset

Context

The dataset tabulates the Connecticut population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Connecticut across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2024, the population of Connecticut was 3.68 million, a 0.88% increase year-by-year from 2023. Previously, in 2023, Connecticut population was 3.64 million, an increase of 0.69% compared to a population of 3.62 million in 2022. Over the last 20 plus years, between 2000 and 2024, population of Connecticut increased by 263,563. In this period, the peak population was 3.68 million in the year 2024. The numbers suggest that the population has not reached its peak yet and is showing a trend of further growth. Source: U.S. Census Bureau Population Estimates Program (PEP).

About this dataset

Context

The dataset tabulates the data for the Connecticut population pyramid, which represents the Connecticut population distribution across age and gender, using estimates from the U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates. It lists the male and female population for each age group, along with the total population for those age groups. Higher numbers at the bottom of the table suggest population growth, whereas higher numbers at the top indicate declining birth rates. Furthermore, the dataset can be utilized to understand the youth dependency ratio, old-age dependency ratio, total dependency ratio, and potential support ratio.

Key observations

• Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Connecticut, is 25.2.
• Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Connecticut, is 27.6.
• Total dependency ratio for Connecticut is 52.9.
• Potential support ratio, which is the number of youth (working age population) per elderly, for Connecticut is 3.6.
