At a glance (2023)
Cost of living is the statewide price level for Connecticut (state avg).
The cost of living runs about 4% above the national average. These figures describe all residents, not just tax filers, come from separate sources than the migration data on this page, and do not indicate why anyone moved.
Not enough data to report
Too few tax filers moved to or from New Haven County, CT for the IRS to publish migration figures above its disclosure threshold in the 2022–2023 filing years. To protect taxpayer privacy, the IRS withholds flows that involve too few returns, which most often affects the smallest counties. Figures may appear in other years. The population and local context below come from Census and other federal sources, a separate universe from the IRS filer data. How the data works.
