In this article, we'll explore most of the 190+ data points we have for California, covering popular demographics statistics like household income, race, age and gender, educational attainment, poverty, housing, and transportation.

Richest Zip Codes in California

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

1 94027 San Mateo County $539,992.00
2 94028 San Mateo County, Santa Clara County $396,740.00

The chart below shows the average household income by age in California.

  • Under 25
    $44,205.00

Average Household Income

A very commonly asked question is "what is the average household income in California?". 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 California is $111,622.00.

15.11% of households in California 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 California 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 California

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 California easier to view.

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

Per Capita Income

The per capita income is the average income of all people in California. This is calculated by dividing the total income of all people in California by the total number of people in California.

It differs from the average or mean household income because it includes all people in California and not just the people who earn an income (i.e. children, retirees, unemployed, etc.).

The per capita income in California is $38,576.00.

Population in California by Race and Ethnicity

The total population in California is currently 39,346,023 people.

Population of California by Age and Gender

Another very important demographics statistic for California 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.

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 California.

  • Master's degree or higher
    15.85%
  • Bachelor's degree
    37.89%
  • Some college or associate's degree
    10.21%
  • High school diploma or equivalent
    31.30%
  • Less than high school diploma
    4.74%

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 California 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 California 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 California that are over the age of 16.

The current population in California that are over the age of 16 is 31,499,704 people.

The unemployment rate in California is 36.10%, which means 11,370,542 people are unemployed.

Median Age in California

The median age is an interesting metric because it gives us an idea of the age distribution of people in California. 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 California is 37 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:
