Haven't seen that one; I liked the 'Burbs w/ Tom Hanks, tho'....
Urbis is Latin for the wall of a city. If you lived outside the wall, you were suburbium. When a piece of land (predominantly tired farmland) outside of a city, is divided up to make residential lots, the whole property that was divided is then called a subdivision, and would be located in the suburbs.
A subdivision is a type of a community, and is a type of a neighborhood. However, a residential section within a city can also be a community and a neighborhood, but it may not be correct to call it a subdivision; it just depends on how that residential section came into being.
When I was in surveying class years ago, one of the major exercises they pressed upon us was taking a piece of land and figuring out how best to divide it into the most lots of a certain minimum size to maximize the profitability of the land sales. There's a reason why I am not a surveyor: I don't like little lots.
Driving around older and newer neighborhoods around town here, there is a distinct difference. The older houses away from the downtown area from the 50's and 60's and 70's are smaller, but have larger yards. The new subdivisions that have come about over the past decade or so, the houses are a lot larger, but they are on smaller lots, where you could spit out your window and hit your neighbors.
If I had to move into a "new" neighborhood (and at one time, we had bought a lot in a subdivision to build on to do that), we bought a really large lot on a curve to maximize how much elbow room our house would have, and was also one that would have had a private backyard (I don't like the idea of being in my backyard with all of my neighbors looking out of their kitchen windows, watching what I'm doing... not that I'm doing anything weird, but, I don't want to be under a glass).
When material prices skyrocketed a few years ago, we then decided to buy an existing house. It's in a neighborhood that is an older subdivision.. it was divided up almost 40 years ago, and the house was built a few years later. It's not a big house, but it's on a large wooded lot (almost 2 acres), with a very private backyard. Really friendly neighbors (we're having a cookout on Saturday for the four homes on our corner), yet we're all very unobtrusive... if you need a hand, we're all goad to help, but if you want to be left alone, we don't stick our noses into each other's business....
FWIW...
