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...
