How does commuting reshape the places people commute from?

Daytime populations fall, local shops and services lose trade to the workplace town, house prices rise as commuters bid for housing, and the resident population becomes more affluent but less locally attached.

Distinguish between internal and international migration in shaping place profiles.

Internal migration redistributes population within a country, often draining rural and post-industrial areas of young adults, whereas international migration adds new ethnic, linguistic and religious groups and usually a younger age structure.

Why does selective migration change a place's age structure?

Migrants are disproportionately young adults, so places that lose them age rapidly while places that receive them gain workers and, in time, higher birth rates.

Give an example of a resource flow that created a place's identity.

Coal from the South Wales valleys drew in workers, built terraced pit villages and chapels, and tied the region to the export docks at Cardiff and Barry.

How can a flow of technology change a place's economic profile?

Broadband, automation or a new production method can allow new industries to locate in a place, or can destroy existing employment by replacing workers, as containerisation did to dockside labour.
