Residual interpretation

• Model significantly over-predicts flows between Dynamic London and Footloose, Middle Class Commuter Britain, and under-predicts flows within Footloose, Middle Class Commuter Britain - Why?

• Likely cause partially associated with the under-prediction of flows within the Footloose cluster (3rd highest at 30-44):

• With many migrants tethered to the cluster through employment in the Capital, moves unlikely to be related to change in status (student to employed or employed to retired) – more likely residential improvement (increase in family size?)
• Therefore, distance unlikely to depress within cluster moves, leading to large model under-prediction

Notes:

Footloose cluster characterised by in-migration of migrants from London in mid to late 20s in higher socio-economic groups, but model still over predicts…
