Presentation Transcript

  1. Changing Population Structure

  2. 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

  3. 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

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

  5. 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)

  6. 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

  7. Spatial variations in the LEDW • Tanzania – Dar es Salem

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

  9. Youthful Population in India

  10. Ageing populations in the MEDW • The regressive population structure
