Bad map

Im suspicious of the map showing the distribution of lactose intolerance. https://commons.wikimedia.org/wiki/File:Worldwide_prevalence_of_lactose_intolerance_in_recent_populations.jpg

Why would populations in Iceland and Greenland have 80-100% lactose intolerant, while the rest of Scandanavia is 0-15%?

The areas don't follow political boundaries. — Preceding unsigned comment added by Aero13792468 (talk • contribs) 07:27, 16 April 2022 (UTC)[reply]

Yes it's pretty bad. According to the original source the percentage was calculated per country, so it's strange that it doesn't align with political boundaries, but they don't cite the sources for their data so it's impossible to investigate why. We talked about replacing it a few years ago, which led to the second, more accurate, map being added, but it didn't have the western hemisphere so we kept both. Maybe now there's enough data available to produce a good map of the whole world?

Greenland does make sense though. Its population is 90% ethnically Inuit and has very high rates of lactose intolerance. – Joe (talk) 07:14, 19 April 2022 (UTC)[reply]

The current map is very inaccurate. Another obvious error is that it seemingly implies that lactose intolerance in Italy is lower than in Spain, when the opposite is true (72% of the population might be lactose intolerant in Italy, compared to 29% in Spain. I've seen many sources supporting this. https://milk.procon.org/lactose-intolerance-by-country/). I've seen I remember seeing another map in this article some time ago that was much better -- it only showed Europe, though. I don't know what happened to this other map. Schweinchen (talk) 22:39, 12 August 2022 (UTC)[reply]

Yes, map is terrible. I think it's more likely to be made on stereotypes and prejudices than on real estimations. As an example, Uruguay and Argentina are 28th and 33rd in milk consumption per capita rankings. While there isn't official data, academic researchers estimate Uruguay's lactose intolerance to be at 40%. I haven't found a similar estimate for Argentina. In this map, they both appear on the range of 80-100%. Halvenvideo (talk) 19:28, 18 October 2022 (UTC)[reply]
