Learning Objectives
• Recap understanding of the DTM and its relationship to population pyramids of different shapes.
• Be able to describe and explain spatial differences in population structure
• Understand the consequences of changing population structures – ageing population in the MEDW and youthful population in LEDW

Why could population vary spatially?
• Different living standards / level of development between regions
• Different religious, racial or national groups. • Availability of jobs / types of jobs• Uneven effects of migration.• Effects of AIDS in some countries• Decisions about availability of family planning

UK spatial variations
• Retirement towns e.g. Bournemouth will have a regressive and top-heavy structure because of the in-migration of elderly people

UK spatial variations
• New towns e.g. Milton Keynes or Stevenage will have an expanding population – a ‘bulge’ of younger, economically active people (BR will be above average)

UK spatial variations
• University towns e.g. Oxford or Cambridge will have higher proportions of young adults
• Remote rural areas e.g. central Wales will show the effects of the out-migration of young adults

Spatial variations in the LEDW
• Tanzania – Dar es Salem

Youthful populations in the LEDW
• This is known as a progressive population structure – typical of low income LEDCs e.g. Uganda

Ageing populations in the MEDW
• The regressive population structure
