About the Oregon Historical Records Index
The records document the population, property, and agricultural production of the county. They may include census rolls and abstracts, farm schedules, abstract of assessment and census, enumeration of inhabitants and industrial products, and enumeration of inhabitants and military enrollment.
The information varies greatly from one census to the next but may include the number of males and females per age category; head of household; name, age, and gender of household members; occupation and relationship of household members to head of household; and description and value of real and personal property. Information may also include nationality, physical description, birthplace, health, and religion of household members and agricultural production statistics.
