Statistics on the 100 Day City Quiz series (and my own list)

From 1 June to 8 September 2025, there was a featured multiple choice quiz on a new city every day on Jetpunk, called the 100 day Multiple Choice City Quiz series. Some time after it started, I created my own list of 100 cities I would feature if the choice was completely up to me. The overlap between both lists was 77 cities, meaning 23 cities in either list did not appear in the other. The tables below show the breakdown of cities by continent and country, for all countries with at least two cities.

As you can see, the major difference between the two lists is the number of American cities – 28 vs 14, accounting for 61% of the discrepancy. In the Jetpunk list, 68% of cities are from the western world, compared to 52% in my list.

The quizzes also varied significantly in difficulty: After taking each quiz once, my average score for non-American city quizzes was 8.5/10, while for American city quizzes it was only 5.9/10 (for context, I'm from Europe). Out of the eight quizzes I still needed for the badge after the series was done (meaning less than 5/10 correct), all of them were about American cities.

In my view, these two statistics show the significant American bias in the selection of both cities and questions.

These are the 23 cities that appeared on Jetpunk, but not in my list (in order of appearance): Turin, Honolulu, Havana, Detroit, Monaco, Austin, Casablanca, Nashville, Phoenix, Houston, Cleveland, Memphis, Minneapolis, Glasgow, St. Louis, Baltimore, Beirut, Salt Lake City, Pittsburgh, Frankfurt, Portland, Sparta, Vatican City.

In contrast, here are the 23 cities that appear in my list, but not on Jetpunk (roughly in order of importance): São Paulo, Tehran, Lagos, Bogotá, Kuala Lumpur, Hanoi, Belgrade, Dhaka, Karachi, Kolkata, Cape Town, Chennai, Tianjin, Hamburg, Osaka, Xi'an, Bengaluru, Oslo, Nairobi, Brasília, Lyon, Kyoto, Alexandria.

After the series ended, I extended my list to 200 cities. This extension contained 15 of the 23 previously missing cities, again leaving out Monaco, Nashville, Memphis, Minneapolis, Beirut, Salt Lake City, Sparta, and Vatican City (note that I don't consider the Vatican its own city, otherwise it would have appeared). Of the 100 new cities, 35 are in Asia, 25 in Europe, 17 in North America, 7 in South America, 11 in Africa, and 5 in Australia. The US provides eleven cities, China ten, and the UK, Germany, India, and Australia three each.
