Conclusions

• Spatial interaction models have shown the large influence of spatial structure on flows within the system

• Many of the flows between clusters the inevitable consequence of ‘social gravity’ – origin and destination migrant masses and the average distance between districts within clusters - the pattern is stable over time

• Model residuals point to non-spatial system influences acting most heavily on flows within and between Dynamic London, Student Towns and Cities and Footloose, Middle Class, Commuter Britain

• Different clusters appear to have particular life-course associations which can offer some explanations for migration patterns between 1999 and 2008 where spatial interaction models cannot account for the whole story
