Germans often switch to English when they hear an accent or hesitation
Though I really doubt your anecdotes, I lived in Berlin for years as a non-German speaker, you have a lot of native speakers all around, you often do not notice when you’re not integrated but once you start following native Germans they bring you to groups and places where the language is way more common.
Last time I was in Berlin, I had to pretend to be Finnish to avoid speaking English and practice my German. That guy was a native German speaker. But I came across plenty of people who did not speak good German but were local residents. So I don't disbelieve her. I spent time in Dresden years ago, and it was easy for me to find Germans to speak with (nowadays, I think that may be different as youngsters are all drilled in American English.) Sächsisch is a somewhat strange accent, but at least it is a native dialect. I already know someone else's broken German, I'm not trying to learn their broken German.
I think the time to be in Berlin was the eighties and nineties. Even 1980s era East Berlin appears to have had some appeal (according to East Germans I've interacted with, despite issues with the Stasi.) Outside of the touristy parts, the modern suburbs are fast evolving into just another global city with non-descript glass and steel cylinders filled with junk food outlets and Air BnB. (Not that East German era architecture is that distinctive either.)
Another trick I've learnt sometimes is to drop into a broad Scottish accent so they cannot understand what I am saying in English. But my German is extremely rusty nowadays.
Is Germany not enough diverse for you?
It's an anecdotal evidence, but while looking for a job I liked looking up employees on linkedin, then looking up the leadership on company's website. First one would always be much more diverse than the second one
My grandparents had many brothers and sisters each and life was harder back then, but it was easier to raise a large family than today. What changed? Taxes, with direct and indirect effects.
Contraception. Children weren't optional back then, they just happened naturally.
> As of 2024, around 17.4 million people living in Germany, or 20.9% of the population, are first-generation immigrants, while the population with a migrant background in the wider sense stood at approximately 25.2 million, accounting for 30.2% of the total population of 83.5 million
Thats a very misleading statistic
