Changing Population Structure
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
Youthful Population in India
Ageing populations in the MEDW The regressive population structure
The worldwide distribution of people aged 65 and over
