Historic Oregon Population

It is important to note that due to racial predjudices held at the time, Native Americans in the region were not counted until about 1900. In fact, in the 1890 Census of Oregon, it is noted that 3,937 Native people living on reservations were "specially enumerated," implying that they were not previously counted. According to the National Archives' website, few Native people were identified in the fedral decentenial census prior to 1900, and were not identified in the census from 1790 to 1840 at all.


The slider runs from 1840, around the time Oregon (or "Oregon Country" as it was first called) was first claimed as a US territory, to 2000, around the last time county boundaries in Oregon were changed.
