Description:

Abstract:

Population density for determining geographic areas that meet the population density requirements of the National Fire Plan. Population density was determined using tax lot data, where it existed and was available. Elsewhere, a process was used to assign the population of each census block to the geographic area most likely to have dwellings - on private land and near roads. The population density is based upon this area. Seasonal and resort communities (second homes) are largely overlooked by census data. Results were classified into 5 density classes: Unpopulated, scattered, rural, suburban, urban and non-forest. See GIS Process for Identifying Communities At Risk.doc.

Purpose:

Oregon Communities At Risk assessment for 2004 for the National Fire Plan. WUI Code was used to deliniate areas meeting the population density criteria in the National Fire Plan and determine a value for Life.

Overview_Description:

Entity_and_Attribute_Overview:

Population density was determined using tax lot data, where it existed and was available. Elsewhere, a process was used to assign the population of each census block to the geographic area most likely to have dwellings - on private land and near roads. The population density is based upon this area. Seasonal and resort communities (second homes) are largely overlooked by census data. Results were classified into 5 density classes.

Entity_and_Attribute_Detail_Citation:

Results were classified into 5 density classes as follows: Population Per Square Mile(dweelings per 40 acres), 0(0) = 0 (unpopul), 0.1-28(0-0.9) =1 (scattered), 28-111(1-3.9) = 2 (rural), 112 -560(4-19.9) =3 (suburban), 560 - 3731(20-99) = 4 (urban); 3732(100)+=5 (non-forest).
