For the people talking about populations, are you sure it wasnt simply a matter of your city folks moving from low wealth to medium to high?
When you start putting down the parks and such to generate high wealth areas your possibly doing so and losing accommodation numbers on those plots.
I've built low-medium wealth cities which have had large numbers, and high wealth cities which have had far fewer, some of which have had about 50% people in the city as visitors/tourists (however its labelled in the game), so i think its down to the fact that buildings can fit more lower wealth people into a building than higher wealth. They're still high density buildings, but rich people want larger living spaces. I think thats almost certainly the primary reason why city populations start to tail off in an unrecoverable manner.
I've not touched it since about 2 weeks after release, and im tempted to have another look, or at least have a go on the sandbox mode with unlimited funds and just make something interesting which i never got around to doing last time.
