Form for the State Statistical Office

The principle of direct collection applies, i.e. the client fills out the form, no third party, not even an architect; for BW, §§ 13 and 14 of the Landesdatenschutzgesetz apply accordingly.

Shame on me. I have just found the completed form (from the architect) in one of the four folders. (Think first then speak) Now the thread from Egon12 has unsettled me a bit. Is it now OK if the architect does this and this is the general practice?

The State Data Protection Act is not designed to annoy you but to protect your right to informational self-determination.

Of course, you can "shruggingly" have your architect fill out a form with your personal data and also have it sent to the statistics office.
However, your architect should actually know that he may only fill out and send the form with your explicit permission.

I also mean that more than just simple house data is requested in the form,

I also mean that more than just mere house data is requested in the form,

Nope.

Name and address are personal data according to the applicable data protection law.

The Federal Constitutional Court ruled in the census decision that under the condition of automated data processing, there is no longer any "insignificant" datum.
Consequently, basically every piece of personal information is protected.

I have also asked the Statistics Office MV to explain why they want to know my name; statistics can also be collected anonymously.
For this, one must know that processing personal data is basically prohibited unless a law permits data processing. (Prohibition with reservation of permission)

Of course, this does not apply to information voluntarily disclosed on the internet, such as profession, name, construction site... construction diaries, etc.
