Education mobility contributes to income mobility and is an important policy target but has received little attention. This paper documents trends (1982–2004) and geographical differences (across US states) in education mobility. We develop mobility measures that respect the unique properties of education attainment. While standard approaches suggest slightly increasing mobility over the sample period, we find that mobility fluctuated, decreasing over roughly the first decade and increasing in the second. Geographic variation in education mobility is correlated with local community and policy factors—such as the existence of high school exit exams. Finally, the South is excluded from national increases in mobility.

教育间的代际流动：地理和时间的变化

教育的流动性促进收入的流动性，是重要的政策目标，但很少受到关注。本文记录了教育流动性的趋势（1982年至2004年）和地理差异（美国各州之间）。我们制定流动性措施，以尊重受教育程度的独特属性。虽然标准方法建议在样本期内迁移率略有增加，但我们发现迁移率波动，大约在前十年下降，而在第二个十年上升。教育流动性的地域差异与当地社区和政策因素（例如高中毕业考试的存在）相关。最后，南方被排除在国家流动性增加之外。
