After World War II, development trends changed and so did neighborhoods.  Developers moved away from established town centers and instead built houses off by themselves, often on land that once was farmed.  Neighborhoods became “subdivisions” or “developments” oriented to cars and attracted people of similar ages and incomes.  The character of these places is different from earlier neighborhoods:  sidewalks with trees to shade them may be missing, socializing happens in the back yard and not on the porch, streets are wider so people drive faster, and everything is a drive away.  These “developments” look and feel a lot different than traditional neighborhoods.
