Demography Flashcards
Immigration
How many people enter the country from elsewhere.
Emigration
How many people leave the country to live elsewhere.
Birth rate
The number of live births per thousand of the population per year.
Births(1)
Long-term decline in the number of births since 1900.
Birth booms
3 ‘baby booms’ in the 20th century the first 2 came after the 2 world wars(1914-18 and 1939-45),returning serviceman and their partners started families that they had postponed.3 boom in the 1960s,1970 birth rate fell and rose and fell and rose by 2001
The total fertility rate(TFR)
Is the average number of children women will have during their fertile years.The Uk fertility has risen over the years BUT its still low
These changes in fertility and birth rates reflect that:
-More women are remaining childless than in the past.
-women are postponing having children=older women may be less fertile an have fewer fertile years remaining and so produce fewer children.
Reasons for the decline in the birth rate
1.Changes in women positions
2.Decline in the infant mortality rate
3.Children are now economic liability
4.Child centredness
1.Changes in women positions
-Increased educational opportunities-girls now do better at school then boys
-Changes in attitudes to family life and woman’s role
-Easier access to divorce
-Access to abortion and reliable contraception,giving women more control over their fertility
-More women in payed employment+laws outlawing unequal pay and sex discrimination
1.Changes in women positions-Sarah Harper
The education of women is the most important reason for the long-term fall in birth and fertility rates.Led to a change in the mindset among women,resulting in fewer children .Women now see other possibilities in life apart from the traditional role of housewife and mother.Many chose to delay childbearing or not have children at all .Smaller families are becoming the norm and bigger ones are less acceptable
2.Decline in the infant mortality rate-Harper
Harper argued a fall in IMR leads to a fall in BR.This is becasue if infants die parents have more children to replace those they have lost therefore increasing BR BUT if infants survive less parents will have more children.
-In 1900 the IMR for the UK was 154=15% of babies die within the first year
2.Decline in the infant mortality rate-
-Improved housing and better sanitation,clean drinking water,reduced infections-infants less developed,catch infections easier.
-A fall in the number of many married women working may have improved health and that of their babies
-better knowledge of hygiene,child health and welfare
-Better nutritions,better for mothers
-Improved services for mothers.
Brass and Kabir
argue that the trend to smaller families began not in rural where IMR first began to fall,but in urban area,where IMR remained higher for longer
3.Children are now economic liability
In the 19th century,children were economic assets to their parents because they could be send out to work from an early age to earn income.
LAWS:banning child labour,introducing compulsory schooling and raising the school leaving age mean that children remain economically dependent on their parents for longer.
CHANGING NORMS:about what children have right to expect from their parents in material terms mean that the cost of bringing up children has risen.
4.Child centredness
Childhood is now socially constructed as a uniquely important period in the individuals life.In terms of family size ,this has encouraged a shift from quantity to quality-parents now have fewer children and lavish more attention and resources on these few
The family
Smaller families mean that women are more likely to be free to go out to work,creates a dual burden earner couple typical of many professional families.HOWEVER,a family size is only one factor.
Better off couples may be able to have larger families and still afford childcare that allows them both to work full-time.
Future trends in BRs
BR,IMR and family size have fallen BUT there has been a slight increase in births since 2001
REASON:increase in immigration,cause in average,mothers from outside the UK have higgher fertility rate than those born in the UK=those babies accounted for 25% of the births
The dependency ratio
Is the relationship between the size of the working or productive part of the population and the size of non-working or dependent part population
-The earnings,savings and taxes of the working population must support the dependent population.Children make up a big part of that dependent population=a fall in the number of children reduces the burden of dependency on the working population
Longer term=fewer babies being born will mean fewer young adults and a smaller working population and so the burden of dependency increases again
The dependency ratio(vanishing children)
Falling IMR mean fewer children=childhood may become a lonelier experience as fewer children will have siblings and more childless adults may mean fewer voices speaking up in support of children interest BUT FEWER CHILDREN WOULD MEAN THEY BECAME MORE VALUED
Public services and policies
A lower BR has consequences for public services,fewer schools,maternity,child health services may be needed.Affects the cost of maternity and paternity leave and the types of housing that need to be built.HOWEVER they are political decisions-instead of reducing the number of schools,the gov could decide to have smaller class sizes.
An ageing population
Effect of women having fewer babies is that the average age of population is rising:there are more old people relative to young people.
Deaths
Is the number of deaths per thousand os the population
Reason for the decline in the death rate(Tranter)
Over 3/4 of the decline in the death rate from 1850 to 1970 was due to a fall in the number of deaths from infectious deseases such as smallpox,measles,tuberculosis etc.Common in young.
-1950s diseases of affluence-wealth,such as hearrt disese and cancers-effected middle age and old.
Improved nutrition(McKeown)
Argues improved nutrition accounted for 1/2 the reduction in death rates and important for reducing the number of deaths from TB.Better nutrition resistance to infection and increased the survival chances of those who did become infected.
McKeown evaluation
Doesnt explain why females who receive a smaller share of the family food supply lived longer than males.
Also doesnt explain why deaths from some infections diseases,such as measles and infant diarrhoea,actually rose at a time of improving nutrition.
Medical improvements
After 1950s,improved medical knowledge techniques and organisation did help to reduce death rates.Introduction of antibiotics,
immunisation,blood transfusion,improved maternity services,as well as NHS in 1948.Surgeries and other developments have reduced deaths of heart diseases
Smoking and diet
A reduction in the number of people smoking.Smokiing has been replaced by obesity which is the new lifestyle epidemic.eg in 2012 1/4 of all UK adults were obese.HOWEVER deaths from obesity have been kept low as a result of drug therapies
Public heath measures
Laws improving housing(less overcrowded accomadation,better ventilated etc),cleaner water,sewage disposal methods,laws to combat the adulteration of food and drink.Clean Air Acts reduced pollution
Other social changes
Reduced death rates
-Smaller families=reduced spread of infections
-The decline of dangerous manual occupations such as mining
-Higher incomes=healthier lifestyle
-Reduction of number of men that smoke=lifestyles changing
-public knowledge of the causes of illness
Smoking and diet(Harper)
Harper suggest that we may be moving to an American health culture where lifestyles are unhealthy but where a long lifespan is achieved by use of costly medication
Life expectancy
How long on average a person born in a given year can expect to live
Life expectancy(2)
Over the past 2 centuries.LE has increased by about 2 years per decade
-Males born in England in 1900 could expect on average to live until they were 50(female 57)
-Males born in England in 2013 can expect to live for 90.7 years(94 females)
Low average expectancy in 1900 cause infants and children didn’t survive beyond early years-if trend to greater longevity continues,Harper predicts we will soon achieve ‘radical longevity’ with many centarians.
