When are buildings abandoned?
I’ve been wondering this for quite a while, and even extensive research didn’t seem to bring up any satisfying insights on this. Trying to master the game, I feel like it’s key to understand when c...

Roads are the key. Roads need to connect residential buildings to service buildings. And of course you need enough services to support the number of residential buildings you have. 1 residential building = 1 capacity/demand.
You need to have enough power, water, sewage, waste management, and fire/police/health coverage.
Traffic affects population and happiness too.
Pollution is another factor.
Residents also dislike living near certain buildings like government (City Storage etc).
Quite often you can tell why residents are unhappy because there's a bubble above the building.
"Are you going to build a power plant or what?"
"I smell smoke..."
"Service Disabled. Reason: No connection to road"
etc etc...
Yeah, there are many things that are immediately affecting happiness. However, I've found that unhappy citizens does not necessarily mean they abandon their home - I can drop below 10% overall happiness by removing all supply buildings (power, water, ...) from the streets. Everyone tends to get unhappy, no one will leave.
If I connect the supply buildings again, happiness will rise, and the first people are going to leave as soon as total happiness is above 15% - but for completely different reasons, such as missing police coverage.
Can anyone confirm that? Different observations?
If you disconnect the road from all services, they move out immediately. I just deleted all my residential roads and my population immediately dropped from 2.6 million to almost 0.
When I created all the roads again, my population was immediately around 1.6 million, and as happiness rose from about 10%, my population increased.
I think when my happiness was back to 55%, I had 2.3 million people. 100% is back to 2.6 million.
If you only have a problem with 1 service, it's only the excessive buildings that are affected, and not to a great degree if all other services are functional.
Interesting! It seems like this is somehow tied to the player level. With my current account, I'm at level 14, and friends of mine at lower level never have heard of citizens moving out. May I ask what level you're at?
That city is level 55. Too bad I didn't take a screenshot. It's a pain doing it again because when I delete the roads, many parks move around and block the path where I need to rebuild.
I just tried the same thing on my level 19 city. As soon as I delete a road that connects a residential building, the population drops immediately. I deleted 1 road and the population immediately dropped from 159k to 140k. I rebuild the road, and the population immediately grows back to 159k.
Residential buildings display "Abandoned Buidling. Reason: No connection to road". Those buildings have 0 connected services without the road. I think if the road was there, but some services were affected, then only part of the residential population would move out. I would have to build more to see that happen.
