I think this is all that needs to be said on these articles.
(There's a lot more that _could_ be said, such as how few actual birthing HN readers there are, but I think the economics is really simple at the root of it.)
Besides, even the countries with really the worst outlook and conditions aren't falling all that fast. Russia since the high point of the 1990s: https://www.worldometers.info/world-population/russia-popula...
This is driving up the demand a lot in central areas.
The houses left behind are not desirable for the same reason so many opt to keep them as summer homes, leading to shortages in the districs as well.
A lot of this has to do with jobs. We've lost a lot of jobs in the districs due to various reasons, and at some point these towns collapse. You need a certain minimum number of folks to have a decent school, a hospital etc. Once population drops too low the hospital gets shut down say and it's downhill from there.
