We expect the overall trend of declining household size to persist. This is supported by an analysis of a panel of 38 countries over time: by the year 2027 on average people will live in a Turkish household – still significantly more than in west European house- holds today. Furthermore, we have assumed a slowdown in migration as push and pull factors for moving are weakening. This stems from the likely narrowing of relative income differentials between regions and dis- economies of agglomeration like rising cost of living and mounting traffic problems that can not be solved quickly enough through infra- structure.
