demography Flashcards
- Births
Birth rate - the number of live births per thousand of the population per year- long term decline of births since 1900- 28.7 in 1900, 12.2 in 2014- baby booms
Total fertility rate TFR
- proportion of women of child bearing age / how fertile they are - TFR = average number of children women will have during their fertile years - risen in recent years from 1.63 in 2001
Reasons for the decline in birth rate - changes in women’s position
- legal rights - education - easier access to divorce - birth control and abortion - change in attitude - educated women are more likely to use family planning and see other possibilities
Reasons for the decline in birth rate - decline in infant mortality rate
- IMR = the number of infants who die before their first birthday, per thousand babies born alive per year - HARPER said the fall in IMR leads to fall in birth rate/1900 IMR in the UK was 15.4, in 2018 it was 3.8 per 1000
During the first half of the 20th century the UK IMR began to fall due to…
- improved housing - better nutrition - better health care - better knowledge of hygiene - fall in number of married women working - improved services, antenatal and postnatal
Decline in IMR cont.
- pro mid 20th century medical factors probably had little effect on IMR - from 1950s things such as mass immunisation, use of antibiotics and improved midwifery contributed to fall - BRASS and KABIR said the trend to smaller families began not in rural areas, where the IMR originally began to fall, but in urban areas, where the IMR remained higher for longer
Reasons for the decline in birth rate - children are now an economic liability
Until the late 19th century children were an economic asset - laws banning child labour, compulsory schooling and raising school leaving age, children are dependent on parents for longer - changing norms is what children have the right to expect, parents therefore feel less able or willing to have a large family
Reasons for the decline in birth rate - childcenteredness
- links to childhood topic - childhood is now socially constructed as an uniquely important period in the individuals life, encouraged a shift from quantity to quality
The effects of changes in fertility - the family
Smaller families mean women are more likely to be free to go to work, creating the dual earner couple but family size is only one factor - eg better off couple are able to have large families and still afford childcare allows them both to work
The effects of changes in fertility - the dependancy ratio
Relationship between working (independent) and non working (dependant) parts of the population. Less children means ‘reduces the burden of dependancy’ but in the long term there will be a smaller working population and the burden of dependancy may begin to increase again
Vanishing children
Childhood may become lonelier, more childless adults might mean less voices speaking up for them or childhood might become more valued
The effects of changes in fertility - public services and policies
Fewer schools, child health and maternity services needed. Affects to maternity and paternity leave and the types of home built but many of these are political decisions - eg instead of reducing the number of schools the government could decide to have smaller classes - ageing population is rising because women are having fewer babies, the average age is the population rising. This will have an effect on the type of services needed
- Deaths
The death rate is the number of deaths per thousand of the population per year. In 1900, the death rate stood at 19 whereas by 2012 it had more than halved to 8.9 - the death rate had already began falling from about 1870 and continued to do so until 1930 - it rose slightly during the 1930s and the 1940s, the period of the Great Depression, followed by WW2 but since the 1950s it has slightly declined
Reasons for the decline in death rate - improved nutrition
- MCKEOWN argues that improved nutrition accounted for up to half the reduction in death rates and was particularly important in reducing the number of deaths from TB. Better nutrition increases resistance to infection and increased survival chances of those who do become infected - however, he does not explain why females who receive small share of the family food supply have survived longer than men and why deaths for some diseases rose at a time of improving nutrition
Reasons for the decline in death rate - medical improvements
After the 1950s, improved medical knowledge, techniques and organisation did help to reduce death rates- introduction of antibiotics/ immunisation - blood transfusion - improved maternity services / nhsMore recently, improved medication, bypass surgery and other developments have reduced deaths from heart disease by 1/3
Reasons for the decline in death rate - smoking and diet
According to HARPER, the greatest fall in death rates in recent decades has been from a reduction in smokers - in 1971 the Public Cigarette Smoking Act made it illegal for tobacco companies to advertise cigs anywhere, in 2007 it became illegal to smoke in any pub, restaurant, club, vehicles - obesity increased and has replaced smoking as the lifestyle epidemic - deaths from obesity have been kept low as a result of drug therapies
Reasons for the decline in death rate - public health measures
- improved housing - purer drinking water - laws to combat the adulteration of food and drink - the pasturation of milk - improved sewage disposal methods - clean air acts reduced air pollution such as the smog that led to 4000 deaths in 5 days in 1952
