A

It is a bugle or increase in the number of working adults in a population.

56
Q

Why does a demographic dividend occur?

A

Due to a decrease in TFR, allowing accelerated economical growth.
People recognise that less children are dying (therefore less fertility) this causes less people to have kids. The life expectancy is still low. This happens in a lag through, so a bulge is created. Life expectancies are low, fertility rates are low to the population is mainly working adults. Dependency ratio declines = demographic dividend.

57
Q

What is a decline in fertility associated with?

A

decline in child mortality rates and an increase in life expectancy.

58
Q

Benefits of a demographic dividend

A
  • increased labour supply
  • benefits the economy
  • increase in savings (+ investments, fuel economy)
  • decrease in fertility rate result in healthier women
  • less societal pressure (having kids)
  • better health and educational outcomes as parents can focus on
    -ONE child
  • increasing GDP
  • decreasing dependency ratio
59
Q

Main idea of demographic dividend

A

People are having less children

60
Q

Difficulty of attaining and maintaining the demographic dividend

A

in LIC’s life expectancy can be as low as 40 years.
In developing countries, birth rates remain extremely high

61
Q

What allows us to maintain a demographic dividend?

A

Low child births and decreasing child mortality rate

62
Q

What is a fact about child/ infant health

A

Children born less than 2 years after the previous birth habe much higher risk of dying( up to 3 times higher)

63
Q

How can a demographic dividend be attained?
