This map reflects the most recent redistricting, which was completed in 1991.
Precinct boarders are subject to a variety of factors.
However, changing demographics, new legislation and shifts in more predominate political boundaries, can lead to new precinct borders. Before precinct boundaries are decided upon, congressional, commissioner, and school district lines are solidified. It is then the job of the County Elections official to draw precinct boarders with these districts, precinct size, and community cohesiveness in mind. Ideally, relative homogeneity is desired in a given precinct, with as few splits and complications as possible. Currently, precincts within Lane County are more or less restricted to 2000 registered voters, but because boundaries are redrawn only once a decade, it is impossible to maintain an exact number in all districts.
