Knowledge Organiser: The Changing UK
Key Terms
- Deindustrialisation — loss of manufacturing; UK concentrated in North 1970s–90s
- North-South divide — persistent economic, health, employment gap
- Urban regeneration — renewing derelict areas through investment
- Ageing population — 18% aged 65+ now; 25% by 2045
- Net migration — arrivals minus departures; 745,000 in 2022
- Global city — London: 40% born abroad; 300+ languages; 25% UK GDP
- Gentrification — rising values displacing original residents
- Agglomeration — self-reinforcing concentration of economic activity
- Replacement fertility — 2.1 children/woman; UK at 1.49
Key Statistics
- UK population 2024: ~68 million (50 million in 1950)
- Net migration 2022: 745,000 (ONS all-time record)
- Fertility rate: 1.49 (below replacement 2.1)
- London GDP per capita: £55,000+ vs North East ~£20,000
- Life expectancy: 83 yrs (Kensington) vs 74 yrs (Blackpool)
- MediaCityUK: 10,000+ jobs; £1bn+ investment; 2011
- London average house price: ~£520,000 (2024)
- Consett Steelworks: 3,500 jobs lost 1980 in a town of 30,000
Key Case Studies
- Salford Quays/MediaCityUK: derelict docks (closed 1982) → media hub; BBC 1,500 staff 2011; 250+ companies; doughnut effect critique
- Consett Steelworks: closed 1980; 3,500 jobs lost in a town of 30,000 — deindustrialisation impact example
- London: global city; City of London 40% of global FX; 9m population; 40% foreign-born; 300+ languages
- HS2: Phase 1 (London–Birmingham) under construction; Phase 2 (northern legs) cancelled October 2023
Must-Know Facts
- Deindustrialisation cause chain: cheap imports → closures → northern unemployment → skill drain south → less investment → divide widens
- Ageing population consequences: NHS pressure, pension costs, labour shortages
- Regeneration critique: relocates not creates jobs; gentrification; doughnut effect
- North-South divide self-reinforcing: agglomeration effect keeps skills and investment in London
- Mnemonic: UK CHANGES (Urbanisation, Knowledge economy, City dominance, Housing, Ageing, North-South, Globalisation, East-West connectivity, Social change)
Common Mistakes
- Claiming regeneration fully solves deindustrialisation: Salford Quays/MediaCityUK created 10,000+ jobs but the "doughnut effect" leaves surrounding areas (Salford, Ordsall) still deprived — regeneration changes places more easily than it changes the lives of original residents
- Treating the North-South divide as only economic: The divide has health, educational and social dimensions — use the 9-year life expectancy gap (83 in Kensington vs 74 in Blackpool) and not just GVA per capita figures
- Confusing net migration with total immigration: Net migration = arrivals minus departures; the 745,000 (2022) figure is net — total arrivals were higher; always clarify which statistic you are using
- Saying the ageing population is only a problem: Older people also contribute economically (spending, volunteering, experience) — evaluation answers need to present both the pressures on NHS/pensions AND potential contributions before making a judgement
