From the Fourteenth census of the United States, Volume 1, a look at Thurston County and how Tono compared at its most bustling:

Olympia 8,537
Tenino 1,420
Yelm 1,224
Tumwater 1,197
Rochester 942
Rainier 776
Tono 625
Bucoda 517

Certainly less than what I assumed when I set out to make the list, Wikipedia had Tono listed over 1,000 in 1920, I was hoping for a top three finish.
