This report contains the estimates for each of the thirty-six counties and the 240 incorporated cities of Oregon from 1975-1986.
The estimates are based on data such as births, deaths, school enrollment, housing, number of privately owned passenger vehicles, income tax returns, voter registration, and other data which are sensitive to population movement.
The methods used to develop the estimates have been tested over a period of years by this agency, agencies in other states, and by the United States Bureau of the Census. These methods produce the most reliable population estimates that can be made.
