Use this to remember the key themes of the UK's changing geography in the 21st century:
U — Urbanisation and regeneration — Salford Quays/MediaCityUK; post-industrial cities reinventing themselves through culture and media; risk that local people miss out
K — Knowledge economy replacing manufacturing — shift from making steel to making media and software; skills mismatch in deindustrialised areas
C — City dominance — London as global mega-city (9 million; 40% born abroad; 300+ languages; 25% of UK GDP) vs post-industrial North
H — Housing pressure — especially South-East; UK needs 300,000 new homes per year but consistently builds fewer; London average £520,000
A — Ageing population — 18% aged 65+ now; 25% by 2045; NHS pressure, pension costs, labour shortages
N — North-South divide — GDP, health, employment, life expectancy gaps; clustering of jobs and skills in London makes it self-reinforcing
G — Globalisation driving service economy — City of London handles 40% of global foreign exchange; international banks; 300+ languages
E — East-West and North-South connectivity — HS2 debate; northern part cancelled 2023; rural digital divide
S — Social change — net migration peaked at about 900,000 (year to June 2023) then fell; diversity; post-Brexit identity debates; fertility below replacement
