editSize of Berlin Metro Area makes no sense
editIn the current revision (link), size of berlin metro area is listed as 30,546 km^2. This number is larger than the entire Brandenburg State, which is 29,480.24 km^2. To put this in perspective, it's like saying San Francisco is larger than California itself. Is this possible? I'm not trying to do original research here. 89.245.157.175 (talk) 20:21, 10 June 2023 (UTC)
- I think the statistic for the Metro Area size comes from this source, Initiativkreis Europäische Metropolregionen in Deutschland. I'm still trying to find out about the rest. Card Zero (talk) 20:59, 10 June 2023 (UTC)
- The area of Brandenburg doesn't include the area of Berlin itself, so your comparison with San Francisco/California is a bit off (San Francisco is part of California, but Berlin is not part of Brandenburg). —Kusma (talk) 21:11, 10 June 2023 (UTC)
- Yes. Old versions of the Brandenburg article said
Brandenburg surrounds but does not include the national capital and city-state Berlin forming a metropolitan area.
Newer versions have rephrased this toBrandenburg surrounds the national capital and city-state of Berlin, and together they form the Berlin/Brandenburg Metropolitan Region.
Probably it was better phrased the first way. Also, the articles should be citing sources for the numbers. Card Zero (talk) 21:15, 10 June 2023 (UTC)
- Yes. Old versions of the Brandenburg article said
- The area of "Haupstadtregion Berlin-Brandenburg" is given here as "30.545,5 qkm". We give the area of the State of Berlin as 891.3 km2 and that of the State of Brandenburg as 29,480.24 km2, together 30,371.5 km2. Can the discrepancy of 174 km2 be due to the source including the areas of lakes not accounted for in our data? --Lambiam 21:13, 10 June 2023 (UTC)
- We also have a Berlin/Brandenburg Metropolitan Region article, which uses that 30.546 km2 figure. Card Zero (talk) 21:20, 10 June 2023 (UTC)
- Ha, it uses "30,545 square kilometres (11,793 sq mi)" in the lead, but "30,370 km2 (11,730 sq mi)" in the infobox. The official website of Berlin-Brandenburg gives the area of Berlin as 891 km2 and that of Brandenburg as 29,654 km2,[1] which adds up to 30,545 km2. The German Wikipedia gives the area of Brandenburg in the infobox as 29,654.16 km2, but the official website of Brandenburg has "seine Gesamtfläche von 29.476 km2",[2] so now the discrepancy has grown to 178 km2. --Lambiam 10:22, 11 June 2023 (UTC)
