Q

what are three important population trends of recent years? how would a 2031 population pyramid show this?

A

the dramatic growth in the size of the older age cohorts (aged 40+)

a continued higher proportion of women compared with men in the oldest cohorts

Q

describe the 4 stages of demographic transition

A

Stage I: High fertility and high mortality. Small population. Slow and varied population growth. High proportion of young people, small proportion of older people.

Stage II: High fertility; mortality begins to decline. Population begins to grow as more children survive. Population explosion may occur, and society may get younger. Small proportion of elderly people.

Stage III: Fertility declines and mortality declines further. Population growth begins to level off at larger size. This is stage of the transition from a young high-growth to an older low-growth population.

Stage IV: Low fertility, low mortality. Low population growth and large proportion of older people in the population.

because they are only considered to be rough indicators of the extent to which one group in a population is dependent on another

encourage people to work past the age of 65 to reduce the demand on public pensions

make improvements in health and delay disability into later life
