In recent years several large studies have found that vertical inter-generational mobility is lower in the United States than in most developed countries. A 1996 paper by Daniel P. McMurrer, Isabel V. Sawhill found "mobility rates seem to be quite similar across countries." However a more recent paper (2007) found a person's parents is a great deal more predictive of their own income in the United States than other countries. The United States had about 1/3 the ratio of mobility of Denmark and less than half that of Canada, Finland and Norway. France, Germany, Sweden, also had higher mobility, with only the United Kingdom being less mobile.
Economic mobility in developing nations (such as those in Africa) is thought to be limited by both historical and global economic factors. Economic mobility is everywere correlated with income and wealth inequality.
