TECHNICAL NOTES Explanation of methods and/or definitions Population estimates: Population data are counts of the number of people living in a defined geographic area by selected demographic characteristics. Population estimates reported by race or ethnicity:The Washington State Department of Health recommends using the "7"groups classification (with Hispanic as race) and dropping the "multiple race" group.The seven groups included are: White only-NH, Black only-NH, American Indian/Alaskan Native only-NH, Asian only-NH, Pacific Islander only-NH, multi-race-NH, Hispanic as race (NH=non Hispanic).This Health Profile reports multi-race-NH as a classification group. Household income: A household consists of all people who occupy a housing unit regardless of relationship.At the Snohomish Health Reporting Area (SHRA) level, household income was based on the average household income for each census tract included in the SHRA. Data used for this estimate are American Community Survey (ACS) 5-year estimates because of their reliability. Unemployment: All civilians 16 years old and over are classified as unemployed if they (1) were neither"at work"nor"with a job but not at work"during the reference week, (2) were actively looking for work during the last four weeks, and (3) were available to accept a job. Also included as unemployed are civilians who did not work at all during the reference week,were waiting to be called back to a job from which they had been laid off, and were available for work except for temporary illness. At the SHRA-level, unemployment was based on the percent of civilians who reported being unemployed in each census tract. Data used for this estimate are ACS 5-year estimates because of their reliability. Family poverty rate:The family poverty estimate is the percentage of families in each census tract included in the SHRA whose income in the past 12 months is below the poverty level. In 2013,the poverty threshold for a family with four people,including two related children under age 18,was$23,624. Data used for this estimate are ACS 5-year estimates because of their reliability. Single-parent households:The percent of single-parent households is the number of male-only and female-only-headed households with one or more related children under age 18 divided by the total number of families with related children under age 18 in an SHRA. Data used for this estimate are ACS 5- year estimates because of their reliability. Adult educational attainment: Educational attainment refers to the highest level of education completed in terms of the highest degree or highest level of school completed among adults ages 25 years and older. At the SHRA-level,the percent of individuals who have less than a 9th grade,9th grade to 12th grade (no diploma), or high school graduate (including equivalency) education along with the percent of individuals who have a bachelor's degree or graduate or professional degree are reported.The ACS 5- year estimates were used in these two calculations because of their reliability. Life expectancy at birth:The average number of years lived for a person born today if observed mortality rates were unchanged over the course of his or her life. Aqe-adiusted mortality:The number of deaths per 100,000 people per year assuming that each SHRA had the same number of people in each age group. Age adjustment was used so that an SHRA with proportionally larger number of older people—who are more likely to die because of their age—does not show a relatively high mortality rate because of the older age of its residents. Years of potential life lost (YPLL):The number of years of life lost due to death before age 65. For example, a person dying at age 64 accrues one YPLL,while a person dying at age 30 accrues 35 YPLL.YPLL provides a measure of the impact of premature mortality on a population. Deaths that occur earlier in life contribute more years of life lost than deaths later in life. 12 NORTH EVERETT HEALTH PROFILE
