But seriously, all that is notable about the US gerrymandering is how unsubtle it is. You could easily have been a bit more subtle about it. You can gerrymander perfectly well just by controlling the council for housing zoning, create a nice ghetto in the middle of your left win areas, and when people move there you can swing a large number of nearby marginal right wing seats due to a decreased number of poor people in those areas.
Or you can do the opposite. Other good tricks include: Scheduling construction work in opposition voting districts during voting, making sure that planning permission for train lines goes through marginal seats, as it tends to bring an influx of young professionals.....
Comment 1: Gerrymandering has a specific definition. It specifically refers to changing the geographic boundaries that define a district. The mechanisms that you are describing would certainly change the characteristic of a district, but they should not be described as gerrymandering.
Comment 2: The reason that gerrymandering is a particular concern is the speed with which it happens. Most of the techniques that you are describing take decades to play out. The individuals that would (potentially) benefit will be long gone. Long lived institutions (like the political parties) often don't have enough information to make this kind of fine grained adjustment. In contrast, here in the US we have a census once ever 10 years. Immediately after the local parties get to go haywire. Things have gotten a lot worse now that there are nice little software packages that let you optimize the district boundaries.
