Child Care:  Notes & Sources

Data Sources

King County data on child care are from the Best Starts for Kids Health Survey (BSKHS) 2017. BSKHS is a survey about the health and well-being of King County children 5th grade and younger. Respondents who reported that their children had some type of regularly scheduled child care or after school care were asked ten questions about the quality of that care, including affordability. Data shown here are for collected in late 2016 and early 2017.

Confidence Interval (also known as error bar) is therange of values that includes the true value 95% of the time. If the confidence intervals of two groups do not overlap, the difference between groups is considered statistically significant (meaning that chance or random variation is unlikely to explain the difference).   

King County regions: The geographic boundaries of the four King County sub-regions (North, Seattle, East, and South) are defined by the aggregation of ZIP codes.

Race/Ethnicity: Federal standards mandate that race and ethnicity (Hispanic origin) are distinct concepts requiring 2 separate questions when collecting data from an individual. "Hispanic origin" is meant to capture the heritage, nationality group, lineage, or country of birth of an individual (or his/her parents) before arriving in the United States. Persons of Hispanic ethnicity can be of any race. Communities Count's terms for racial/ethnic groups are derived from those used by the U.S Census Bureau in 2010.

  • Communities Count terms:  Hispanic, Non-Hispanic, White Non-Hispanic, Black, American Indian/Alaska Native (AIAN), Asian, Native Hawaiian/Pacific Islander (NHPI), White, and Multiple Race (Multiple). Persons of Hispanic ethnicity can be of any race and are included in other racial categories. Racial/ethnic groups are sometimes combined when sample sizes are too small for valid statistical comparisons of more discrete groups. 
  • 2010 Census terms: Hispanic or Latino, Not Hispanic or Latino, White alone (Not Hispanic or Latino),  Black or African American, American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, White, Some Other Race, and Two or More Races.

Statistical Significance: Unless otherwise noted, any difference mentioned in the text is statistically significant (unlikely to have occurred by chance).

Quotes:  Communities Count interviewed 32 King County families across a broad range of racial, cultural, and socioeconomic diversity. We reached out to communities of color, recent immigrants, and residents with limited English proficiency. We interviewed both families with very low household income and those who earned up to median income (about $68,000 for a family of four in 2010). Family structures include single-parent households, couples living in consensual unions, married couples, and extended families. We also interviewed social service providers from agencies such as Crisis Clinic, Hopelink, Multi Service Center, and Child Care Resources, as well as staff from community colleges that offer worker retraining or similar programs to help King County residents find jobs.
