Washtenaw County residents have a median age of 34-years-old as of 2021, according to US Census Data.

Median ages divide a population into two equally sized groups, rather than the average which takes all the ages of Washtenaw County residents and divides it by the number of residents.

OurWorldinData.org, an online project tracking global data and trends, says cities, states, countries and continents with higher median ages typically do better economically and residents earn higher wages than developing countries.

The median age of a United States resident has risen from 29.5-years-old in 1960 to 38.4-years-old in 2019. It has risen fairly consistently by two years every decade since the 1970's.
