Abstract
A decomposition of an inequality measure is proposed in order to compute the role of mobility in the evolution of disparities between European regions. Our results confirm that economic growth when integration process succeeds in the European Union have decreased inequality, narrowing gaps rather than moving low-income regions ahead of higher-income ones. Also, results have revealed the importance of studies about intradistributional movements when we pretend to analyse a regional growth process comparison, although it is not the more relevant factor in the evolution of inequality.

1 Based on covariance properties of the Gini coefficient.
2 Ranks are used as estimators of the accumulative distribution. Lerman and Yitzaki (Citation1989) show a specific analysis for stratified samples.
3 Two new decompositions are used to solve the problem. Finally, both are averaged.
