What made people move there is not what they maintain, and at some point you become just another area with a bunch of houses.
There are a couple things at play here. Obviously, diversity of the population is one of those. Local folks having local kids that stayed around and became the next generation of that towns population meant that local traditions were carried forward. Everything from religious actives to parades, fairs, organizations, etc. All the stuff that makes up local culture.
Now, more and more kids dont stay. They want out. Sometimes they still come back, but not always. So who replaces the local kids? Outsiders who move in. They didn't move in saying - Hey we are here to destroy local culture! But when locals leave for other (sometimes better) opportunity, someone else is going to replace them.
I would imagine that its looked something like this, dates could be adjusted some based on the area:
65 years ago, local kids stayed around. Town grew very little.
45 years ago, local kids left for college at Texas A&M, then came back. Town grew little.
25 years ago, some local kids left for college at Texas A&M, sometimes came back. Town growing steady.
15 years ago, local kids dispersed to many different universities, and most didn't return. Town exploding in growth.
