Richest Zip Codes in Illinois

In the table below, we've ranked the richest zip codes in Illinois 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.

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 Illinois 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 Illinois

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.

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.

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 Illinois because it can show how many people are actively looking for work and how many people are unable to find a job.

Median Age in Illinois

The median age is an interesting metric because it gives us an idea of the age distribution of people in Illinois. 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 Illinois is 38.7 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:
