Information from the archaeological record from 9 culture areas was used to explore the influence of human insecurities on the rate of depopulation in the U.S. Southwest and Mexican Northwest region during the 1300 to 1400s. The authors found that as the sum of human insecurities increased in culture areas, the speed of depopulation also increased. They hope to relate these findings to modern sustainability planning and to advocate with the UN Development Programme for increased human security.
