Common demographic patterns between countries
Demographic transition model
Urbanisation trends (driven by better economic opportunities and services)
Migration influences (e.g. economic disparity, conflict, climate change)
Ageing Populations (due to low fertility and higher LE)
Differences between MEDCs and LEDCs populations
MEDCs - access to education, healthcare and family planning causing low BR, ageing population and shrinking work force, higher urbanisation and slower population growth
LEDCs - High FR and younger population structures, rapid population growth and urban expansion, limited access to Healthcare and education affecting DR
Differences between Stable democracies and authoritarian/conflict affected states populations
Democracies - better social services causing lower FR and DR, immigration policies shape population growth/diversity
Authoritarian/ Conflict - population displacement due to war/persecution, poor infrastructure causing lower LE and higher DR
How social structures affect population
Gender roles - Higher FR, gender equality causing delayed children and smaller families
Education Access - Higher education levels (among women particularly) causing lower FR and increased migration for better opportunities
Religious/Cultural norms - influence family size, migration patterns, attitudes toward contraception
Population pyramid shapes
Constrictive - ageing population, low BR
Expansive - Youthful pop, high FR
Stationary - Balanced age distribution
Expansive pyramid
wide base, Narrow top, found in stages 1-2
Constrictive pyramid
Narrow base, wide middles, found stage 5
Stationary pyramid
Even throughout, found stages 3-4
