Layer name: DEMOGRAPHIC_INDEXSubject category: censusTitle: 2020 Consolidated Demographics IndexFeature Count: 397Feature Type: PolygonAbstract: This layer was originally created to support the STAR Rating System objective EE-4: Equitable Services & Access Community Level Outcomes for King County. Three demographics are combined into one attribute to determine King County services access analysis by census tract. Each demographic: English proficiency, people of color, and household income, was applied to census tracts separately. This demographic information is based on the 2016 - 2020 American Community Survey from the Census Bureau. The demographic was sorted into five classes using the Natural Breaks classification. Then each class was given a score: 1 for the first class, 2 for the second class, 3 for the third class, etc. Next, each census tract received a score based on the class it was in: 1 if it was in the first class, 2 if it was in the second class, 3 if it was in the third class, etc. So each census tract will have a score for English proficiency (ESL_Score), a score for people of color (RE_Score), and a score for household income (Income_Score). These scores were added up (TotalScore) and an evenly weight average was determined (WeightedTotal333333). Thus each score for the census tracts represents a combination of demographics where lower scores mean a wealthier, less diverse community and higher scores mean more diverse, less wealthy community.Purpose: Combines three demographic characteristics into one category. English proficiency, people of color, and household income are scored and combined into a equal weighted score.Status: CompleteUpdated: None plannedTime period of content: (single date,as YYYYMMDD):: Time period of content: (date range, as YYYYMMDD):: 20130101 - 20171231Spatial reference: WA State Plane NorthFGDC Documentation: Classic or FAQOpen Data Availability: YesPlace Keywords: Pacific NW, King County, WA, Washington state, Theme Keywords: census, demographics, persons of color, median income, english, ESL, American Community Survey, Lineage: Not available
