健康不平等研究旨在确定健康梯度的变化是否可能是由于不同健康状况的人通过选择性分类在不同地区和/或社会阶层之间流动。由于结论各不相同，部分原因是采用了不同的方法，因此有必要建立一个适当的框架，在这个框架内，有可能确定空间或社会流动是否以及如何有助于随着时间的推移改变健康方面的空间和社会不平等。在本文中，我们提出了实证的例子，展示了一种方法学的方法来确定总的健康变化，并讨论了选择性排序的影响，不断变化的健康梯度的结果。我们的实证工作表明，通过社会流动性和移民进行选择性分类可能会扩大人口中的健康不平等。我们的结论是，有必要重新汇总相关时间点的微观数据，以确定特定健康结果的人口分布变化。简单地确定个人是否因过渡状态而在健康方面有所不同，可能意味着对总体变化的影响，但并不能证明这一点。
Health inequalities research seeks to determine if changing health gradients may be due to the movement of differently healthy people between area types and/or social classes through a process of selective sorting. Because conclusions vary, in part because of different approaches employed, there is a need to establish an appropriate framework within which it is possible to determine whether and how spatial or social mobility contributes to changing spatial and social inequalities in health over time. In this paper, we present empirical examples demonstrating a methodological approach needed to determine aggregate changes in health, and discuss the results in terms of the impact of selective sorting on changing health gradients. Our empirical work illustrates that selective sorting through social mobility and migration can contribute to widening health inequalities in the population. We conclude that it is necessary to re-aggregate microdata at the relevant time points of interest to determine changes in the population distribution of a particular health outcome. Simply establishing whether individuals vary in health by transition status may imply an impact on aggregate changes but does not demonstrate it.
