Construction costs are currently skyrocketing

Did you all also receive a letter to participate in the census? After a bit of googling, apparently every property owner is contacted … why do they want to know what I use for heating and how many people live with me, they already have my registration data and the building application

yes, we also got it and clicked through it in 5 minutes

I received one in the rental apartment. Yesterday in the mailbox, next Thursday someone will come by. Gigantic lead time for participation being mandatory...

And have you ever worked with official data? The left hand often doesn’t know what the right hand is doing because nothing is synchronized. There’s a reason why you have to submit birth certificates to several offices for one child...

And which employee is supposed to compile this data now? Residents' registration office != building authority.
And the heating system listed in the building permit is then +99 years old in the building?

I fear you haven’t had many points of contact with our administration so far. There is no Big Data going on. Just because everything is in some folder in some archive doesn’t mean you have unrestricted access to this data. The opposite is the case.

A medium-sized municipality with about 35,000 inhabitants can’t even tell you exactly how many residents it has. It fluctuates by at least +/- 500.

UPDATE: was faster, but apparently has the same view on things.

Unfortunately, that is actually the case... I work in a municipal administration and am always irritated by what we CANNOT find out through data records. Despite business registrations and the like, for example, it is impossible for us to simply filter the local businesses with more than x employees or similar. When it comes to the responsibilities of other authorities, it then becomes almost impossible.

So the district with the most housing stock with a lot of single-family houses is probably Treptow-Köpenick after Steglitz-Zehlendorf, and it has been more dark red than red since ancient times.

Well, I actually thought of the districts Biesdorf, Kaulsdorf, and Mahlsdorf, that is, the district Marzahn-Hellersdorf. At least, in two articles it was described as the largest single-family housing settlement area in Europe. That everyone only thinks of Plattenbauten with Marzahn-Hellersdorf is only due to the Berlin district reform of 2001. And even in Hellersdorf, as far as I know, there are still some single-family houses standing.
I think in the last district elections, it was black and red to dark red with two light blue blemishes. But I could be wrong.

The funny thing is: When you register a business, data is gladly shared with everyone who wants money somehow (IHK, tax office, etc.). But when it comes to simplifying things for the citizen, someone always comes up with "data protection."
