Richest Zip Codes in Connecticut
In the table below, we've ranked the richest zip codes in Connecticut based on the average (or mean) household income. To do this, we only look at zip codes that have a population of at least 500 people and a reasonable margin of error for the data.
If the margin of error for the mean income is greater than 50% of the estimate, we don't use it. This is to try and make the data less likely to be skewed by outliers with very small population areas or estimates that are not very accurate.
