As the United States celebrates its 250th anniversary this year, Seattle ranks the 18th largest city in the nation.
A two-earner Seattle household at the city median pays roughly $874 a month more for infant care than a comparable family in the median U.S. metro. King County's $27,653 annual price for a center-based infant slot is the eighth-highest county figure in the index, $10,490 above the national median, and consumes 22.7% of Seattle's $121,984 median household income. The supply side is tighter still: 32 licensed slots per 100 working-parent kids under five, formally a childcare desert. Centers compete for caregivers against Amazon warehouses and Costco floors, where starting pay clears $21 an hour for less specialized work. Three-quarters of Seattle mothers with children under six are in the labor force. Seattle ranks 79th of 250.
Key highlights & actionable takeaways
- 79th nationally, score 56 (Moderate) — held back by King County's $27,653 infant-care price tag and childcare-desert slot count.
- A typical Seattle family spends 22.7% of household income on one infant slot — about $10,490 above the national infant-care figure.
- 74.7% of mothers with kids under six in the labor force — second only to Portland in the Pacific cohort and well above Washington's 62.8%.
Actionable takeaways
- Centers compete for caregivers against Amazon warehouses, Costco, and Starbucks corporate. Childcare workers earn $19.32/hr — solid in absolute dollars but only 66% of King County's $29.21 single-adult living wage. The bidding war is the supply-side mechanic that lengthens infant-room waitlists.
- The two-kids-in-care number is the local punch. A Seattle household with one infant and one toddler in center care simultaneously clears $51,960 a year — more than four times the city's median annual rent of $23,976. That's the figure that lands with families.
- Childcare costs $1.15 per dollar of rent here. A two-earner Seattle household at the city median pays roughly $874 a month more for infant care than a comparable family in the median U.S. metro — concrete grounding for the broader cost-of-childcare conversation.
Affordability — 35/100
A year of infant center care in King County now runs $27,653 — about $10,490 above the $17,163 national median and the eighth-highest county figure in the index. Against Seattle's $121,984 median household income, that single tuition bill consumes 22.7% of pre-tax pay. Toddler care drops to $24,307 and family-childcare-home rates land near $21,175. Statewide, the Washington average sits at $21,767 and 22.9% of income; Seattle sits roughly $5,900 a year above that state-average price for the same infant room.
Childcare to rent runs 1.15 here — for every dollar of shelter, families pay $1.15 toward a single child's care. The lived implication is concrete. A two-earner Seattle household at the city median pays roughly $874 a month more for infant care than a comparable family in the median U.S. metro. For a household with two children under five in center care simultaneously, the combined infant-and-toddler bill clears $51,960 a year — more than four times Seattle's median annual rent of $23,976.
Supply — 51/100
Roughly 32 licensed slots exist for every 100 kids under five with working parents in King County, which formally classifies the county as a childcare desert under the standard "more than three kids per slot" threshold. The headline density — 7.13 licensed establishments per 1,000 children under five — looks healthy on paper and runs nearly 70% above the national average of 4.21. The contradiction resolves in scale: Seattle has the providers, but the slots inside them don't keep pace with the 146,740 King County kids under five with all available parents working. Statewide, Washington logs a 45.3% gap between potential demand and licensed supply per the Bipartisan Policy Center — meaning nearly half of Washington children who could need care don't have a licensed slot waiting.
Workforce — 79/100
The median King County childcare worker earns $19.32 an hour — about $40,180 a year — equal to 66.1% of the local single-adult living wage of $29.21. That ratio puts Seattle workers ahead of the 62.6% national figure and just under Washington state's 68.4%. Roughly 2,220 OEWS-counted workers staff the metro's licensed centers and homes. The wage looks strong in absolute dollars, but King County's living-wage threshold is the issue: a $19.32 hourly rate that would clear a living wage in much of Ohio falls a third short here. Centers competing with Amazon warehouse pay ($22+/hr starting), Starbucks corporate ($24+/hr), and Costco floor wages ($21+/hr) for the same labor pool are losing the bidding war, which lengthens infant-room waitlists and concentrates turnover.
Family strain — 87/100
Mothers of kids under six work outside the home at a 74.7% rate in Seattle — second only to Portland in this regional cohort and 6.5 points above the national 68.2%. Single-parent share is 23.2%, well below the 31.8% US figure and one of the lowest among Beverly's anchor cities. Read together, those two numbers describe a city where the second earner is the norm, household structure is comparatively stable, and the demand for full-time care is driven less by single-parent necessity than by the math of two professional careers. With 31,396 children under five and 71.9% of them in households where every parent works, Seattle's care demand is functionally universal among local families.
Policy support — 57/100
Washington enrolls 17% of 4-year-olds and 8% of 3-year-olds in state pre-K, spending $12,808 per enrolled child and meeting 8.2 of NIEER's 10 quality benchmarks — among the strongest quality scores in the country. The state's CCDF subsidy reaches 19.8% of eligible families and serves about 24,500 children a month. Washington's Paid Family and Medical Leave program, in effect since 2020, offers up to 12 weeks at 90% wage replacement — one of the most generous state programs in the country. Policy is measured at the state level; every Washington city in this index inherits the same 57.1 score.
In-home care in Seattle
Seattle's in-home care market is the deepest in the Pacific Northwest. Full-time live-out nanny rates across King County typically fall in the $25-35/hr range for a single-child placement, with experienced career nannies, multiples specialists, and households on the Eastside (Bellevue, Mercer Island, Kirkland) routinely clearing the high end. Nanny shares between two families — long a Seattle-specific workaround for the cost gap between a center slot and a private nanny — have grown into a mainstream option, often landing each participating family in the $18-22/hr range per share. The au pair channel has a meaningful presence in dual-tech-career households needing live-in coverage for nonstandard schedules, with State Department-designated J-1 sponsor agencies placing several hundred au pairs annually across the metro. For families running the math on $55,000 a year for two kids in center care, an in-home arrangement is increasingly the path that pencils.
Methodology: The the score is a 0-100 composite score across five dimensions: Affordability (30 pts), Supply (25 pts), Workforce Health (15 pts), Family Strain (15 pts), and Policy Support (15 pts). City-level prices and supply use the city's primary containing county. Policy Support is measured at the state level. Full methodology and data sources: beverly.io/research/methodology.
