What the numbers mean for dating in Washington
Washington's 7.81 million residents include an estimated 1.37 million women aged 18 to 44, about 2.5% of the national pool. The Seattle metro, at just over four million, dominates and hosts Amazon, Microsoft, and Boeing — an employment base that has drawn hundreds of thousands of young transplants over the past two decades. Spokane anchors a 600,000-person market in the east, and Tacoma's Joint Base Lewis-McChord adds one of the country's largest military populations to the Puget Sound region.
The median Washingtonian is 38.2 years old, and about 40% of women 25 and older hold a bachelor's degree, among the top ten states. Roughly 34% of adult women have never married. The famous caveat is Seattle's sex ratio: tech hiring has produced one of the most male-skewed young-adult populations of any major U.S. metro, with studies finding on the order of 110 to 120 single men per 100 single women in some age brackets — numerically great for women, challenging for men.
A national probability from our calculator scales roughly with a state's share of the US population: preferences matching 1% of US women translate to about 13,670 women in Washington. State demographics like education and marriage rates shift the real figure up or down.
