Unlike the average age, the median age is the age that splits a population into two halves: one half younger than the median and the other half older. While the average can be influenced by outliers, the median is generally less susceptible to extreme values, making it a more reliable measure of the population's age tendency.

According to the 2021 census, the median age varied across different ethnicities in the state. White residents had a median age of 38 years old, while the median age for African Americans was 26 years old. The Asian population was median age is 42 years old, and Hispanics had a median age of 27 years old.

Data also shows that Tumwater's population leaned towards the 25 to 29 years demographic.
