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 year
there has been a long term decline in the number of births since 1900.
there have been fluctuations in births, with three 'baby booms' in the 20th century
THE TOTAL FERTILITY RATE
the factors determining the birth rate, firstly the proportion of women who
are of childbearing age and secondly how fertile they are
the total fertility rate is the average number of children women will have during their fertile years
the UK's TFR has risen in recent years, but still much lower than the past
these changes in fertility and birth rate reflect the idea that:
more women are remaining childless than in the past
women are postponing having children, the average age for giving birth today is 30
REASONS FOR THE DECLINE IN THE BIRTH RATE
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
1. CHANGES IN WOMENS POSITION
there were major changes in the position of women during the 20th century
legal equality with men, including the right to vote
increased educational oppurtunities- girls now do better at school than boys
more women in paid employment, plus laws outlawing equal pay and sex discrimination
changes in attitudes to family life and womens role
easier access to divorce
access to abortion and reliable contraception, giving women more control over their fertility
2. DECLINE IN THE INFANT MORTALITY RATE
the infant mortality rate measures the number of infants who die before their first
birthday, per thousand babies born alive, per year
the UK's IMR has began to fall. this is due to:
improved housing and better sanitation, such as clean drinking water and reduced infections
better nutrition, including that of mothers
better knowledge of hygiene, child health and welfare
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
3. CHILDREN ARE NOW AN ECONOMIC LIABILITY
until the late 19th century, children were economic assets to their parents because they could be sent
out to work from an early age to earn an income
since the late 19th century children have gradually become an economic liability
laws: banning child labour, introducing compulsory education
and raising the school leaving age mean that children remain
dependent on their parents for longer
changing norms: about what children have a right to expect from their
parents in material terms means that the cost of raising children has risen
4. CHILD CENTREDNESS
the increasing child centredness both of the family and society means that
childhood is now socially constructed as a uniquely important period in the
individuals life
this has encouraged a shift from 'quantity' to 'quality'- parents now have fewer children and lavish more attention and rescouces on these few
EFFECTS OF CHANGES IN FERTILITY
THE FAMILY
smaller families means that women are more likely to be free to go out to work, creating a
dual earner couple typical of many professional families
better off couples may be able to have larger families and still afford childcare that allows them both to work full time
THE DEPENDENCY RATIO
this is the relationship between the size of the working part of the population and the
size of the non working part of the population, also known as the dependent
the earnings, savings and taxes from the working population must support the dependent
children make up a large part of the dependent population, so a fall in children reduces the burden of dependency on the working population
PUBLIC SERVICES AND POLICIES
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 parernity leave and the types of housing that need to be built
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
DEATHS
REASON FOR THE DECLINE IN DEATH RATE
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 diptheria,
measles, smallpox, typhiod and TB.
deaths from infectious diseases were commonest in the young and the most of the
decline in the death rate occured among infants, children and young adults
there are several possible reasons for the decline in deaths from infection. it is possible that the population began to
develop some natural resistance or that some diseases became less powerful
IMPROVED NUTRITION: accounted for half the reduction in death rates. better
nutrition increased the survival chances of those who did become infected
MEDICAL IMPROVEMENTS: medical improvements played almost no part in the reduction of deaths from infectious
diseases. after the 1950s, improved medical knowledge, techniques and organisation did help to reduce death rates.
the introduction of anibiotics, immunisation, blood transfusion, improved maternity services as well as
the setting up of the NHS in 1948
SMOKING AND DIET: in the 21st century, obesity has replaced smoking as the new lifestyle epidemic. deaths from obesity have been kept low as a result
of drug therapies. we could be moving onto an 'american' health culture where lifestyles are unhealthy but where a long lifespan is achieved by the use
of costly medication
PUBLIC HEALTH MEASURES: in the 20th century, more effective central and local governments with the necessary power to
pass and enforce laws led to a range of improvements in public health
these included improvments in housing, purer drinking water, laws to conbat the adulteration
of food and drink and improved sewage disposal methods
the clean air act reduced air pollution, such as smog
LIFE EXPECTANCY
refers to how long on average a person born in a given year can expect to live
as death rates have fallen, life expectancy has increased
one reason for lower average life expectancy in 1900 was the fact that so
many infants and children did not survive beyond the early years of life
if the trend for greater long lifespan continues, harper predicts that we will soon achieve 'radical longevity'
with many more people aged over 100
THE AGEING POPULATION
the average age of the UK population is rising. there are
fewer young people and more older people
the ageing population is caused by 3 factors: INCREASING LIFE
EXPECTANCY, DECLINING INFANT MORTALITY, DECLINING FERTILITY
EFFECTS OF AN AGEING POPULATION
PUBLIC SERVICES
older people consume a larger proportion of
services such as health and social care
however we should be aware of over-generalising, since many people
remain in relatively good health well into old age
in addition, an ageing population may also mean changes to policies and
provision of housing, transport or other services
ONE-PERSON PENSIONER HOUSEHOLDS
the number of pensioners living alone has increased and one-person
pensioner households now account for about 12.5% of all households
among the over 75s, there are twice as many women as men
THE DEPENDENCY RATIO
as the number of retired people rises, this increases the
dependency ratio and the burden on the working population
in an ageing population this is offset by a declining
number of dependent children
AGEISM, MODERNITY AND POSTMODERNITY
modern society is the growth of ageism- the negative
stereotyping and unequal treatment of people based on their age
most sociologists argue that ageism is the result of 'structured dependency'. the
old age are largely excluded from paid work laving them economically dependent
on families and the state
age becomes an important role allocation, the old are therefore excluded from a
role in the labour force and made dependent and powerless
INEQUALITY AMONG THE OLD
CLASS: the middle class have better occupational pensions and greater savings from higher
salaries. poorer old people have a shorter life expectancy and suffer more infirmity
GENDER: womens lower earnings and career breaks as carers means lower
pensions. they are also subject to sexist as well as ageist stereotyping
often restricts the freedom of older people to choose an identity
older people also face discrimination that limits their choices
MIGRATION
IMMIGRATION: movement into a society
EMIGRATION: movement out
NET MIGRATION: difference between the numbers of immigrants and the numbers of
emigrants, and is expressed as a net increase or a net decrease due to migration
IMMIGRATION
very few immigrant were non-white
by 2011, ethnic minority groups accounted for 14% of the population
one result has seen a greater diversity of family patterns
a series of immigration and nationality acts placed severe
restrictions on non-white immigration.
EMIGRATION
the main reasons for emigration have been economic: push factors:
such as economic recession and employment at home
pull factors: such as higher wages or better oppurtunites abroad
these economic reasons for migration contrast with those of some other
groups, who have been driven to migrate by religious, political or radical
persecution
THE IMPACT OF MIGRATION ON UK POPULATION STRUCTURE
POPULATION SIZE: the UK population is currently growing, partly as a result of immigration
net migration is high with more immigrants than emigrants
natural increase: brits exceeding deaths. births to UK born mothers
remain low. births to non- UK born mothers are higher
AGE STRUCTURE: immigration lowers the average age of the population both directly and indirectly =.
DIRECTLY: immigrants are generally younger, INDIRECTLY: being younger, immigrants are more fertile and produce more babies
THE DEPENDENCY RATIO: immigration has 3 effects
immigrants are more likely to be of working age and
this helps lower the dependecy ratio
immigrants are more likely to be children, thereby increasing the ratio
the longer a gap is settled in the country, the closer their fertility
rate comes to the national average, reducing their overall impact
GLOBALISATION AND MIGRATION
GLOBALISATION is the idea that barriers between
societies are disappearing and people are becoming
increasingly interconnected
globalisation is the result of many processes,
including the growth of communication
systems and global media
ACCELERATION
there has been a speeding up of the rate of migration. in 2013, 862,000 people either entered or left the UK
DIFFERENTIATION
there are many types of migrant
these include: permanent settlers, temporary workers, spouses and
forced migrants such as refugees and asylum seekers
globalisation is increasing the diversity of types of migrant
SUPER DIVERSITY: migrants now come from a much wider range of countries. even
within a single ethnic group, individuals differ in terms of their legal status
there are class differences among migrants
CITIZENS: with full citizenship rights, the UK state has made it harder for immigrants to acquire these rights
DENIZENS: are privileged foreign nationals welcomed by the state, eg highly paid employees
HELOTS: are the most exploited group. 'disposable units of labour power', a reserve army of
labour. they are unskilled, poorly paid work and include illegally trafficked workers
