A social change may be immigration. With new nationalities migrating into a country social change is inevitably unavoidable. Communities experiencing an influx of Latino immigrants most likely will develop new establishments that are based around Latin Americans, thus a social change. Religion is another example. Say a new pastor moves into your community that teaches a new kind of religion. Some people may decide they like it and start to go to his church instead of the Catholic Church down the block evoking a social change in the community. Economic situations may bring a social change. Times of hardship change almost every aspect of daily life. Economic downfalls can destroy communities. Neighbors may no longer live across the street because they can't afford their mortgage payments on their little house. It all leads to social change. I hope this helps answer your question.
