What the numbers mean for dating in Idaho
Idaho has been one of America's fastest-growing states, reaching about 1.97 million residents with an estimated 334,000 women aged 18 to 44 — about 0.62% of the national pool. Growth centers overwhelmingly on the Boise metro, now over 800,000 people and absorbing waves of transplants from California and Washington. Beyond the Treasure Valley, Idaho Falls, Twin Falls, and the college town of Moscow anchor much smaller markets separated by long stretches of mountain and farmland.
Idaho's median age of 37.0 is younger than the nation's, buoyed by large families in its substantial Latter-day Saint population, concentrated in the state's southeast. That religious character shapes the dating landscape profoundly: only about 26% of adult women have never married — nearly the lowest share in the country — because first marriages here happen years earlier than the national norm. Around 31% of women 25 and older hold a bachelor's degree, with Boise and the university towns running higher.
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 3,340 women in Idaho. State demographics like education and marriage rates shift the real figure up or down.
