The tendency in several European countries toward an increase in commuting has sometimes been presented as one possible explanation for why interregional migration propensity has decreased. This study is an attempt to investigate the impact of job availability on migration propensity over time. Other studies have shown that the size of the labour market has an effect on migration propensity. The same effect was found in this study. However, no evidence was found that job availability has become more influential on migration over time. The process of extended commuting has thus not made commuting opportunities more important as explanatory factor for interregional migration.
