These graphs make zero sense due to the break in the line and overlap between them in 2010. So they should be deleted as OOS due to the inaccurate data. Or did the population completely die off while being replaced to about the same level at exactly the same time?

- Hello,
- The graphs rely on the official figures of the statistics department of Brandenburg and Berlin. Due to the census 2011 there have been two figures for the yearend of 2011. Under Bevölkerungsentwicklung und Flächen der kreisfreien Städte, Landkreise und Gemeinden im Land Brandenburg 2011 you find that the population of Ahrensfelde on December 31st, 2011 was 13002 inhabitants. When you open Bevölkerungsentwicklung und Flächen der kreisfreien Städte, Landkreise und Gemeinden im Land Brandenburg 2012 you find that the population of Ahrensfelde started the year 2012 with 12727 inhabitants. This drop of 275 within a day was the result of the new figures that came up with the census in 2011.
- This gap of nearly 2% of the population of Ahrensfelde resulted from the difference between the yearly update of the local registers and the data collection from scratch done by the census. The city of Berlin lost about 180,000 inhabitants due to the census. The single big reason were foreign students. In order to start their studies they had to register with the local authorities. But when they finished their studies and went home, they often forgot to check-out. So they stayed as sleeping members in the statistics. Only the census made evident that they weren't inhabitants of Berlin any more.
- When I devised the graph I thought about just let the "figures flow". But this would have lead to steep unaccountable drops with a lot of municipalities. So I decided to have an overlap and a break in 2011. This is explicitly to show that there is a special situation. I admit that I should give a hint about this interruption of the line. Since in 2024 the figures of the 2022 census will be published with new breaks and overlaps I will include a remark in to the graphics when update it.
- I feel offended by the accusation of using inaccurate data. As you have seen I only use the officially published data. I would have preferred that you contacted me in order to find out what the reasons of the graphically anomalities are. Please retire the deletion request.

- Thanks for the explanation. Just to clarify, by "inaccurate data" I meant the graph was inaccurate, not the data that you based it on, which it seems like you agree with. I guess you could explain the overlap and disparities better in the file descriptions or something, but graphs don't usually have breaks or overlaps like that to begin with. Usually there's a dotted line or something going up or down like in File:Bevölkerungsprognosen Ahrensfelde.pdf to signify a major change in the numbers. Otherwise it looks like the population was both the old and new numbers at the same time and that they are separate data points, which is clearly wrong. --Adamant1 (talk) 19:46, 12 May 2024 (UTC)
