Richest Zip Codes in Idaho
In the table below, we've ranked the richest zip codes in Idaho 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.
|Rank||ZIP Code||County||Mean Income|
|1||83616||Ada County, Gem County||$144,860.00|
|4||83716||Ada County, Boise County, Elmore County||$125,563.00|

Average Household Income
A very commonly asked question is "what is the average household income in Idaho?". 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.
The average (or mean) household income in Idaho is $77,399.00.
5.65% of households in Idaho 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 Idaho 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 Idaho
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 Idaho easier to view.

Whether you want to target products or services to a particular race or ethnicity, or provide housing and new businesses to improve areas with a larger ethnic minority population, this data is very valuable for discovering suitable areas.
The chart below breaks down the population and percentage for each race and ethnicity in Idaho.

Population of Idaho by Age and Gender
Another very important demographics statistic for Idaho is the age and gender of the population. The age and gender of the population can be used to track trends in population growth or decline, and for businesses, the data can be used to identify people important to you and your business need.
In the table below, we show age groups at a 10 year granularity for ease of use. The raw data, which can be purchased above, includes age and gender at a 5 year granularity.

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 Idaho.
Master's degree or higher11.70%
Some college or associate's degree14.12%
High school diploma or equivalent37.15%
Less than high school diploma3.17%
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 Idaho 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 Idaho 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 Idaho that are over the age of 16.
The current population in Idaho that are over the age of 16 is 1,405,245 people.
The unemployment rate in Idaho is 36.80%, which means 517,268 people are unemployed.
Median Age in Idaho
The median age is an interesting metric because it gives us an idea of the age distribution of people in Idaho. 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 Idaho is 36.8 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:
