Where an adult-nightlife district is actually documented

A four-step flag on 901 cities: none, low, moderate, high. 44 are high, 95 moderate, 589 carry nothing known.

World map with dots marking cities flagged high or moderate for adult-nightlife visibility

Large dots are high visibility, small dots moderate. Cities flagged none or low are not drawn.

What the chart says

It is a flag, not a score. There is no order inside a step: every high-visibility city carries the same value, and no venue, price or quality claim is made anywhere.
Visibility is not legality. Several high-visibility cities sit in countries where the activity is illegal, and several countries where it is legal have no flagged city at all. Sex work law is a separate country-level metric.
589 of 901 cities carry nothing known. That is the normal case, and an absence here means nothing was documented, not that nothing exists.

All 139

Every city flagged moderate or high, high first, then alphabetical inside each step.

Alphabetical inside a step on purpose: no ranking exists, so any other order would invent one.

Where this is wrong

Hand classification from public open-source context. Not an official legal finding, not fieldwork, and not a venue guide.
An absence is a documentation gap. Cities with less English-language coverage are more likely to read as none.
Legality and enforcement are separate questions and change faster than this classification does. Check the country page before drawing any conclusion.
Nothing here is scored. The flag is excluded from the Quiz score and the Geomaxxing Score.

Sources

Manual city-level classification from public open-source context, seeded by the Wikipedia list of red-light districts and local reporting. Not an official legal finding.

Sex work law, at country level, sits on each market's deep-dive under countries.
