Forget ratios. Here is where the extra women actually are.

Women minus men, ages 20–39, in each city's own census. 408 of 895 cities carry a female surplus — 3.97 million women in total.

Horizontal bar chart of the 28 cities with the largest surplus of women aged 20 to 39, led by London at 123,657

Bars are coloured by that city's ratio on the site's 94/100/112 scale. A big surplus with a moderate ratio simply means a big city.

What the chart says

A ratio is a rate; nobody feels a rate. London's 91.9 sounds unremarkable until it is stated as 123,657 more women than men in the 20–39 band alone.
Size beats skew. The largest surpluses are big cities with moderate ratios, not small cities with extreme ones. The most female-skewed city on the site is nowhere near the top ten.

All 408

The chart shows 28. Here is every city carrying a surplus, largest first.

Surplus is women minus men in the 20–39 band, from that city's own census arrays. Cities with more men than women are excluded from this table by definition.

Where this is wrong

A surplus is not availability. It counts people in an age band. It says nothing about who is single, who is interested, or who would consider a foreigner.
23 cities are held back, not missing. Every UK city, and most of Taiwan, Thailand and South Korea, ship census arrays that are not population counts — a few hundred people against multi-million cities, and Belfast computing to 158 men per 100 women off 173 people. They are excluded until the source is rebuilt.
Population is the linked administrative unit, not always the metro. New York City's census arrays cover a borough, Mexico City's a delegación, Japan's four cities a ward. Those ratios are real ratios of real places, but read them as that unit rather than as the whole metro.
Surpluses do not add up across cities. Two cities of 20,000 each are not a pool of 40,000 to anyone who can only live in one of them.

Sources

Age by sex: national statistics offices per market — methodology.

The same numbers drive the research desk, where you can filter and sort every city here, and women-majority cities.

Same numbers, filterable — and the sub-national maps at sex ratio by region break these markets down below city level.

The per-market deep-dives — 13 tabs of cost, visa, tax, safety and sub-national ratio for one country — are behind the Pro gate. Everything on this page is not.
