This tiny New Mexico town has the smallest population, as well as the highest concentration of millionaires, on this list. Chalk up the density of affluence to the National Laboratory, a research facility focused on national security and the county’s largest employer. Since the lab was established in 1943 as site Y of the Manhattan Project, it has drawn some of the world’s top scientific minds with state-of-the-art facilities, currently including more than 1,200 buildings on a 36-square-mile campus, and generous paychecks. In fact, the area’s six-figure median household income is the highest on this list. And relatively low living costs — just 2.9% above the U.S. average — will help wealthy residents hold on to their fortunes.
