Demography Flashcards
factors affecting population
increase:
- births and immigration
decrease:
- deaths and emigration
birth rate
number of live births per thousand
changes in fertility/birth rates:
- more women remain childless
- women are postponing having children, focused on their careers
reasons for long term decline in birth rate since 1900
a range of social, economic, cultural, legal, political and technological factors
Sarah Harper (2012)
- the education of women is the most imp reason for the long term fall in birth and fertility rates
- smaller fams have become the norm, large fams are seen as deviant
Harper - Decline in infant mortality rates
- a fall in IMR leads to a fall in birth rate
- if infants die, parents have more kids to compensate for the lost one
Reasons for IMR fall
- improved housing and sanitation
- better nutrition
- improved services (antenatal/postnatal clinics)
Children are now an economic liability
laws banning child labour - introduced compulsory schooling and raised school leaving age
changing norms - children have a right to expect from their parents
Smaller Vs Larger Families
smaller families mean that women are more likely to be free to go to work to provide, better of families are likely to be larger as they can afford childcare and still both work fulltime
Dependency ratio
the relationship between the size of the working and productive part of the population and the size of the non working/dependent part of the population
Ageing population
there are more old people relative to young people
Decline in death rates - social factors
- improved nutrition
- medical improvements
- smoking and diet
- public heath measures
- other social changes
Thomas McKeown (1972) - improved nutrition
improved nutrition accounted for up to half the reduction in death rates, better nutrition increased resistance to infection
Medical Improvements
played no part before 1950s, however after it helped reduce deaths
- introduction of antibiotics, immunisation, etc.
Public health measures
improvements in housing - producing drier, better ventilated, less overcrowded accom
Other social changes
- decline of dangerous manual occupations
- smaller families = reduced rate of transmission (infection)
- knowledge of cause of illness
- higher incomes
Life expectancy
as death rates have fallen, life expectancy has increased
Class, gender and regional differences
- women generally live longer than men
- Walker (2011), those living in the poorest area (England) die on average 7 yrs earlier than those in richer areas
Ageing population
average age of UK population is rising
- there are fewer young ppl and more old
- older age groups are growing as a proportion of the population whilst younger groups are shrinking
Increasing life expactancy
ppl are living longer into old age
