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.

Average Household Income

A very commonly asked question is "what is the average household income in Connecticut?". The official term for the average household income is the mean household income. The mean household income is the total income of all households divided by the number of households.

14.54% of households in Connecticut are classed as high income households (making $200,000+ per year).

The difference between a median and an average income

The difference between a median and mean household income is that the median income is the middle point of the set of numbers whereas the mean income is an average of all numbers.

Both metrics are important when looking at the income statistics for Connecticut but because the median value doesn't depend on other numbers in the dataset, it doesn't change as much when some of the values are extremely low or extremely high.

Household Income Tiers for Connecticut

We can also look at the household income tiers. This lets you see how many households fall into each of the earnings brackets and what percentage that bracket is of the total number of households.

The chart below shows the household income brackets to see which age groups have the highest median income. The actual data is more granular than these brackets, but we've simplified them into bigger categories to make reviewing the data for Connecticut easier to view.

You can purchase the raw data above, which will have the full income tiers with smaller jumps in household income.

Education Levels

Educational attainment is a very useful statistic that can give insights into other data such as the average household income, unemployment levels, and literacy.

What this means is that it is likely for areas that have higher levels of education to have higher average household incomes, lower unemployment rates, and higher literacy rates.

The chart below shows the educational attainment of the population in Connecticut.

    35.14%

    2.27%

Unemployment Rates

The unemployment rate is the percentage of the population that is actively looking for work but is unable to find a job. The unemployment rate is a very important statistic for Connecticut because it can show how many people are actively looking for work and how many people are unable to find a job.

Lower levels of unemployment is generally seen as a positive sign for the economy. It also makes the government in Connecticut look good because it shows that they are doing a good job of creating jobs, working to capacity, being efficient, and keeping the economy strong.

The unemployment rate is calculated using the total population in Connecticut that are over the age of 16.

The unemployment rate in Connecticut is 34.00%, which means 1,004,654 people are unemployed.

Median Age in Connecticut

The median age is an interesting metric because it gives us an idea of the age distribution of people in Connecticut. You know when you see a median age that it is the age where half of the population is older and half is younger than it.

For demographic studies, this can be used to infer and compare date to things such as birth rates, the age of parents, and so on.

An increasing median age can be a sign of an aging population, which can be a sign of a declining population. This is because older people tend to have fewer children and die more often than younger people.

The median age in Connecticut is 41 years old.

We can also look at the median age by gender to compare the see how each group compares to the total median age:
