The tool organizes a collection of <br />indicators into these four categories. <br />The two census tracts in the study area <br />have an overall ranking of 2 and 5. Each <br />number from 1 to 10 represents 10 percent <br />of communities (or census tracts). For <br />example, Census tract 5100 has a rank of 2 <br />for Environmental Exposures. That means <br />only 10% of communities in Washington State <br />have a lower health disparity (or are less <br />affected by environmental exposures) and 70% <br />have a greater level of disparity (or are more <br />affected by environmental exposures). The <br />indicators are averaged within each theme or <br />Environmental Health Risk Factor. <br />Although the overall rankings for the study <br />area are low to moderate (indicating the <br />area is not disproportionately burdened <br />by environmental health risks), Table 3-9 <br />highlights a few severe disparities within <br />each risk factor that are present in the study <br />area. For example, both census tracts have <br />the highest rank (10) for transportation <br />expense, and they share high ranks in ozone <br />concentration (9, 8). <br />VOLUME I: FEASIBILITY REPORT 1-90 Corridor Easton to Cle Elum Feasibility Study I Sl <br />
