What the chart says

92 of 143 cities carry more women than men in the band. Across the 143 cities the net surplus is 464,775 women aged 20 to 34.
The top of the list is one country, not a region. Honduras takes 8 of the first 12 places, which is a labour-migration signal as much as a demographic one: the men leave, and the census counts who stayed.
A city ratio is not a national ratio. Each row is that city's own census unit, so a capital and a beach town in the same country land far apart.

All 143

Every Latin-American city carried, most female-skewed first.

Surplus is women minus men inside the band, from the same census arrays as the ratio.

Where this is wrong

20 to 34, not 20 to 35. Censuses publish 5-year groups, so the window is 20-24 plus 25-29 plus 30-34. Nothing here reaches age 35.
Latin America is defined here as the Spanish and Portuguese speaking Americas. Belize, Guyana, Suriname, Jamaica, Haiti and Trinidad sit in the same latitudes and are not in this set.
The census unit is not always the city you picture. Some rows are a municipality, some a metro. The level is stated per market on its country page.
A ratio counts people, not availability. It says nothing about who is single, interested, or in your age range.
