We’ve all noticed that Seattle feels like a younger city these days. Census data indicates that change is happening fast.

The number of adults under age 35 has been growing and much faster than in other tech capitals.

Since 2010, the proportion of the city’s population that is under age 35 has jumped 1.4 percent, according to Seattle’s demographer Diana Canzoneri.

In an email to KUOW, Canzoneri said a lot of this jump occurred around 2015 and 2016.

At the same time, San Francisco has also gotten younger, though not as fast. Silicon Valley has gotten slightly older.
