Population and Housing Unit Counts, Oregon, 1990
U.S. Census Bureau · 1993
In the story: 6. The emblem outlives the club, 1930–2010.
CPH-2-39, the volume that supplies 1980 and 1990 — and the first of the two official 1990 figures.
This volume prints Bend at 20,469 for 1990 and 17,263 for 1980. The 2000 and 2010 volumes print the 1990 count as 20,447, flagged “r” for revised.
Both are Census figures and they differ by 22 people. This site uses the revised 20,447 and says so wherever the number appears.
