demography Flashcards
(60 cards)
what is demography?
the study of population, including factors affecting its size and growth
what four factors affect population?
- births and immigration increase the population
- deaths and emigration decrease the population
what is natural change in population?
the number of births minus the number of deaths.
what is net migration?
number of people immigrating into a country, minus the number emigrating from it
how has the UK population grown?
37 million in 1901 to 65 million now, predicted 71 million by 2031
what is the main cause for population growth in the uk?
natural change rather than net migration
what is birth rate?
the number of live births per 1000 of the population per year
how has birth rate been declining?
the long-term decline since, in 1900 it was almost 29. By 2014, it had fallen by more than 60% to 12.2
fluctuations in birth rate
three baby booms were after both of the world wars, and in the 1960s.
the rate fell sharply after 1970s, rose during 1980s and early 1990s, and then fell until recent increase in 2001.
what are the two measures of birth?
- birth rate
- total fertility rate
what is total fertility rate?
the average number of children a woman will have during her fertile ages (15-44)
what was fertility rate in 1960s baby boom
average was 2.95 children per woman
what was fertility rate in 2001
fell to an all-time low of 1.63
what was fertility rate in 2014
1.83
trends in births
- more women are remaining childless
- women are having children later, as the average age in now over 30
what are the reasons for fall in birth rate?
- changes in the position of women
- fall in the infant mortality rate
- children as an economic liability
- child-centredness
how have changes in the position of women contributed to falling birth rate?
- increased educational opportunities
- more women working
- changes in attitudes to family life and women’s role
- easier access to divorce
- easier access to abortion and contraception
how has the fall in infant mortality rate contributed to falling birth rate?
number of infants who die before their first birthday per 1000 babies born alive, per year (IFR). in 1900, it was 154, by 2016, it was 4. If infants survive, parents will have fewer of them.
reasons for the fall in infant mortality rate
in 1950s, IMR began to fall due to mass immunisation, antibiotics, and improves midwifery and obstetrics.
improved housing, sanitation, nutrition, knowledge of hygiene and child health, and health services for mothers and children
how have children as an economic liability contributed to falling birth rate
until late 19th century, children were an economic asset, as they worked from an early age. Now:
- law banning child labour and intro of compulsory schooling mean they remain economically dependent for longer
- changing norms about children’s right to a high standard of living raises their cost
this means parents can’t afford to have a large family.
how has child-centredness contributed to falling birth rate?
childhood is now socially constructed as a uniquely important period, leading to a shift from ‘quantity’ to ‘quality’. Parents now have fewer children, and lavish more attention and resources on these few.
what are the effects of falling birth rate?
dependency ratio- relationship between the size of working population and size of the non-working population.
- children as a large part of the dependent population who are supported by the working population’s earnings and taxes. fewer children reduces the ‘burden of dependency’ on working population.
fewer public services needed, and less money spent on maternity/ paternity leave. however, these also depend on the political decisions as the government can choose to reduce no of schools or have smaller class sizes.
how have the number of deaths been since 1900
fairly stable at around 600,000 per year. Fluctuations include 1918 flu epidemic and the two world wars
how has the death rate fallen since 1900
number of deaths per 1000 in a year has halved from 19 in 1900 to 8.9 in 2012.
began falling from 1870, continuing until 1930, and rose slightly in 1930s-1940s due to economic depression and WW2. since 1950s, it has declined slightly.
