Demography Flashcards
1
Q
Demography
A
- family and population are closely linked. E.g, new members of the population are mostly born into and raised by families, while the kinda of care they receive from their family affects their chances of survival. Similarly, as the study of Anderson shows, when people migrate from country to country or religion to religion, they often rely on kin to facilitate their move
- the study of populations and their characteristics is called demography. These characteristics include:
- size
- age structure - the average age of the population raising or falling
- births - how many babies are born
- deaths - how many people have died
- immigration - how many people enter the country from elsewhere (IN)
- emigration - how many people leave the country to love somewhere else (OUT)

Q
Uk population growth
A
- until the 1980s, uk population was largely the product of natural change - that is, the result of there being more briths than deaths. However, since the 1980s most of the growth has come from net migration- that is, more immigration than emigration

Q
Births
A
- the number of births obviously affects population size. Sociologists use the concept of birth rate to measure births. The birth rate is defined as the number of live births per thousand of the population per yer
- there has been a long term decline in the number of births since 1900. In that year, England and wales had a birth relate of 28.7, but 2014 it had fallen to an estimated 12.2
- however, there have been fluctuations in birthday, with three ‘baby booms’ in the 20th century. The first two came after the two world wars, as retiring servicemen and their partners had started families that they had postponed during the war years
- thee was a third baby boom in the 1960s, after which the birth rate fell sharply during the 1970s. The rate rose during the 1980s, before falling again after the early 1990s, with some increase since 2001
4
Q
The total fertility rate
A
- the factors determining the birth rate are, firstly, the proportion of women who are child rearing age and, secondly, how fertile they are - that is, how many children they have. The total fertility rate (TFR) is the average number of children women will have during their years
- the TFR has risen in recent years, but it is still much lower than in the past. From an all time low of 1.63 children per women in 2001, or rose to 1.83 by 2014. However, this is still far lower than the peak of 2.95 children per women reached in 1964 during the 1960s baby boom
- these changes in fertility and birth rates reflect the fact that:
- women are remaining childless than in the past
- women are postponing having children: the average age for giving birth is now 30, and fertility rates for women in their 30s and 40s are on the increase. Older women may be less fertile and have fewer fertile tears remaining, and so they produce fewer children
5
Q
Reasons for the decline in the birth rate
A
- sociologists have identified a number of reasons for the long term decline in the birth rate since 1900. These reasons involve a range of social, economic, cultural, legal, political and technological factors.
6
Q
- Changes in women’s positions
A
- there were major changes in the positions of women during the 20th century. These include:
- legal equality with men, including the right to vote
- increased educational opportunities- girls now do better at school than boys
- more women in paid employment, plus laws outlining unequal pay and sex discrimination
- changes in attitudes to family life and women’s roles
- easier access to divorce
- access to abortion and reliable contraception, giving women more control over their fertility
- according to harper, the education of women its the most important reason for the long term fall in birth and fertility rates. It has led to a change in mind set among women, resulting in fewer children. Not only are educated women more likely to use family planning, they now see other possibilities in life apart from the traditional role of housewife and mother. Many are choosing to delay childbearing, or not to have children at all, in order to pursue a career. E.g, in 2012, one in five women aged 45 was childless - double the number of 25 years earlier
- harper also notes that, once a pattern of low fertility lasts for more than one generation, cultural norms about family size change. Smaller families become the norm and large ones come to be seen as deviant or less acceptable
7
Q
- Decline in the infant mortality rate (IMR)
A
- the IMR measures the number of infants who die before their first birthday, per thousand babies born alive, pre year
- harper argues that a fall in IMR leads to a fall in the birth rate. This is because, if many infants die, parents have more children to replace those they have lost, thereby increasing the birth rate. By contrast, if infants survive, parents will have fewer of them
- in 1900, the IMR for the uk was 154. In other words, over 15% of babies died within their first year. These figures are higher than those of less developed countries today. E.g, in 2014, the world’s highest estimated IMR was that of Afghanistan, at 117.
- during the first half of the 20th century, the uks IMR began to fall. This was due to several reasons:
- improved housing and better sanitation, such as flush toilets and clean drinking water, reduced the infectious disease. Infants are much more susceptible to infection because of their less developed immune system
- better nutrition, including that of mothers
- better knowledge of hygiene, child health and welfare, often spread via women’s magazines
- a fall in the number of married women working may have improved their health and that of their babies
- improved services for mothers and children, such as postnatal clinics
- before the mid century, it is doubtful whether specifically medical factors had much effect on the IMR - although indirectly, the medical profession had a significant impact through its campaigns to improve public health measures
- however, from about 1950s, medical factors began to play a greater role. E.g, mass immunisation agagsint childhood diseases such as whooping cough, and later measles, the use of antibiotics to fight infection and improved midwifery and obstetric techniques, all contributed to a continuing fall in the IMR
- as a result of all the above developments, by 1950 the uks IMR had fallen to 30 and by 2012 it stood at 4 - barely one fortieth of its 1900 figure.
- however, while many sociologists claim that the falling IMR led to a fall in birth rates, brass and kabir argue that the trend to smaller families began not in rural areas, where the IMR first began to fall, but in urban areas, where the IMR remained higher for longer

Q
- Children are now an economic liability
A
- until the late 19th century, children were economic assets to their parents because they could be sent to work from an early age to earn an income. However, since the late 19th century children have gradually become an economic liability
- laws - banning child labour, introducing compulsory schooling and raising the school leaving age mean that children remain economically dependent on their parents for longer and longer
- changing norms - about what children have a right to expect from their parents in material terms mean that the cost of brining up children has risen
- as a result of these financial pressures, parents now feel less able or willing than in the past to have a large family
9
Q
- Child centredness
A
- the increasing child centredness both of the family and society as a whole means that 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
10
Q
Future trends in birth rates
A
- as a result of all of these factors, birth rates, fertility rates, and family sizes have fallen over the last century. However, as we saw earlier, there has been a slight increase in births since 2001.
- one reason for this is the increase in immigration because, on average, mothers from outside the uk have a higher fertility rate than those born outside the uk accounted for 25% of all births in 2011. However, the projection for the period up to 2041 expects the annual number of births to be fairly constant, at around 800,000 per year
11
Q
Effects of changes in fertility
A
- changers in the number of babies born affect serval aspects of society. These include the family, the dependency ratio, and public services and policies
12
Q
The family
A
- smaller families mean that women are more likely to be free to go out work, this creating the dual earner couple typical of many professional families. However, family size is only one factor here. E.g, better off couples may be able to have larger families and still afford childcare that allows them both to work full time
13
Q
The dependency ratio
A
- the dependency ratio is 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
- the earnings, savings and taxes of the working population must support the dependant population. Children make up a large part of the dependant population, so a fall in the number of children reduces the ‘burden of dependancy’ on the working population
- however, in the longer term, fewer babies being born will mean fewer young adults and a smaller working population and so the burden of dependency may begin to increase again
- vanishing children falling fertility rates mean fewer children. As a result, 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 interests. Conversely, fewer children could mean they will come to be more valued
14
Q
Public services and polices
A
- a lower birth rate has consequences for public services. E.g, fewer schools and maternity and child health services may be needed. It also affects the cost of maternity and paternity leave and the types of housing that need to be built. However, we should remember that many of these are political decisions. E.g, instead of reducing the number of schools, the government could decide to have smaller class sizes
- an ageing population - one effect of women having fewer babies is that the average age of the population is rising: there are more old people relative to young people. This ageing of the population has a number of important effects.
15
Q
Deaths
A
- 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 has more than halved, to 8.9
- the death rate has already begun falling from about 1970 and continued to do so until 1930. It rose slightly during the 1930s and 1940s - the period of the great economic depression, followed by ww2 - but since the 1950w it has declined slightly
16
Q
Reasons for the decline in the death rate
A
- there are several reason why the death rate declined during the 20th century.
- according to tranter, over three quarters of the decline in the death rate from about 1850 to 1970 was due to a fall in the number of deaths from infectious diseases such as measles, smallpox etc. deaths from infectious disease were commonest in the young and most of the decline in the death rate occurred among infants, children and young adults
- by the 19590s, so called ‘diseases of affluence’ such as heart disease and cancers had replaced infectious diseases as the main cause of death. These degenerative diseases affect the middle aged and the old more than the young
- there are several possible reasons for the decline in the deaths from infection. It is possible that the population began to develop some natural resistance or that some diseases became less powerful
- however, social factors probably had a much greater impact on infectious diseases. These include:
- improved nutrition
- medical improvement
- smoking and diet
- public health measure
17
Q
Improved nutrition
A
- McKeown argues that improved nutrition accounted for up to half the reduction in death rate, and was particularly important in reducing the number of deaths from TB. Better nutrition increased resistance to infection and increased the survival chances of those who did become infected
- however, McKeown does not explain why females, who receive smaller share of the family food supply, lived longer than males. Similarly, he fails to explain why deaths from some infectious diseases, such as measles, actually rose at a time of improving nutrition
18
Q
Medical improvements
A
- before the 1950s, despite some important innovations, medical improvements played almost no part in the reduction of deaths from infectious disease
- however, after the 1950s, improved medical knowledge, techniques and organisation did help to reduce death rates. Advances included the introduction of antibiotics, immunisation, blood transfusion, improved maternity services as well as as the setting up of the national health service in 1948. More recently, improved medication, by pass surgery and other developments have reduced deaths from heart disease by one third
