We discuss the cultural power of changes in nation-level residential mobility. Using a theoretically-informed analysis of mobility trends across the developed world, we argue that a shift from a culture full of people moving their residence to a culture full of people staying in place is associated with decreases, among its residents, in individualism, happiness, trust, optimism, and endorsement of the notion that hard work leads to success. We use the United States as a case study: while the U.S. has historically been a highly-residentially-mobile nation, yearly moves in the U.S. are halved from rates in the 1970s and quartered from rates in the late 19th century. In the past four decades, the proportion of Americans who are stuck in neighborhoods they no longer wish to live in is up nearly 50%. We discuss how high rates of mobility may have originally shaped American culture, and how recent declines in residential mobility may relate to current feelings of cultural stagnation. Finally, we speculate on future trends in American mobility and the consequences of a society where citizens increasingly find themselves stuck in place.
