Demography Flashcards
Demography
The study of a population and its characteristics
Trend of birth rates
long term decline since 1990 where the birth rate went from 28.7 to 10.2 in 2020.
Baby Boom’s
There were 3 baby booms in the 20th century, the first two came after the two World Wars, the third one was in the 1960’s
Total Fertility Rate: Changes in fertility and birth rates reflect the fact:
- More women are remaining childless
- Women are postponing having children.
Reasons for the decline in the birth rate
- Changes in women’s position
- Decline in the infant mortality rate
- Children are now an economic liability
- Child Centredness
Changes in women’s position
- legal equality with men
- increased educational opportunities ( Harper (2012) the education of women is the most important reason for the long-term fall in birth & fertility rates.)
- more women in paid employment
- changes in attitudes to family life
- easier access to divorce
- access to abortion & contraception
Decline in infant mortality rate.
Harper argues that a fall in the IMR leads to a fall in the birth rate, as if many infants die parents have to replace them increasing the birth rate. However, it also fell due to :
- improved housing
- better knowledge of hygiene
- improved services
- better nutrition
Medical factors affecting IMR
By 1950 the UK’s IMR had fallen to 30 and by 2023 it was 3.3, this was due to new developments such as mass immunisation against childhood diseases such as whooping cough, measles and the use of antibiotics and improved midwifery contributed to a fall in the IMR.
However, Brass and Kabir 1978 argued that the trend to smaller families began not in rural areas, where IMR first began to fall, but in urban areas where IMR remained higher for longer.
Statistic given for postponing children
In 2012, 1 in 5 women aged 45 were childless, double the number of 25 years ago
Future trends for birth rates
Increased immigration may increase birth rate as mothers outside the UK have a higher fertility rate and they accounted for 25% of all births in 2011, however the projection for up to 2041 expects the annual number of births to be fairly constant at around 800,000 per year
Effects of changes in fertility
The Family
The dependency ratio
Public Services and Policies
Changes in Fertility: The Family
Smaller families mean women are more likely to go back to work, creating dual earner couples though better off couples may be able to have larger families and still afford childcare allowing them to both work full time
Dependency Ratio
The relationship between the size of the working or productive part of the population and the size of the non-working or dependent part of the population, earning, saving, taxes of working population support the dependent population. Children make up large part of dependent population, so less reduces the ‘burden of dependency’ on working population. However less babies means less young adults to become the working population, so the burden of dependency may then increase
Decreased Death Rate: Public Health
In 20th century, more effective central/local government with necessary power to pass and enforce laws led to a range of improvements in public health and quality of environment, including improvements in housing, purer drinking water, laws to combat adulteration of food and drink, pasteurisation of milk, and improved sewage disposal methods (clean air acts reduced air pollution that led to 4000 deaths in five days in 1952)
Life expectancy in the UK
Born in 1900 life expectancy was 50 for males and 57 for females, Born in 2013 life expectancy is 90.7 for males and 94 for females
