You and your family may have moved to a new community while you were growing up, or perhaps other families moved into your hometown. Whether due to shifts in the economy and employment (Goudreau, 2013) or international immigration (Taylor & Cohn, 2012), the people around you are likely to be changing. As such, you must be ready to address cultural differences—not just between nations but also between regions, states, and cities. Even if you don’t physically encounter many people from outside your community, you will almost certainly communicate with new people at some time or another through media.
