The intention of this paper is to establish a statistical correlation between migration and the quality and quantity of houses in Rotterdam and environs at a high level of aggregation. Verification or falsification of correlations involving more variables would require a spectrum of data for all municipalities in the Netherlands which is beyond the scope of this paper. This paper presents primary research data of residential migration and the quality of dwellings in and around Rotterdam. It makes a substantive (historical data) and procedural (research process) contribution to knowledge which is of use to under graduate and post graduate students, as well as to researchers in the town and regional planning field.
