Demographic Trends: Birth Rate, Death Rate, and the Ageing Population

Demography is the study of population — its size, composition, and change. Understanding demographic trends is essential for analysing how family structures and social policies have changed.

Key Demographic Concepts

TermDefinition
Birth rateNumber of live births per 1,000 of the population per year
Death rateNumber of deaths per 1,000 of the population per year
Fertility rateAverage number of children born per woman during her lifetime
Total fertility rate (TFR)The average number of children a woman will have (currently ~1.6 in the UK)
Infant mortality rate (IMR)Number of deaths of infants under 1 year per 1,000 live births
Life expectancyAverage number of years a person is expected to live
Natural changeDifference between birth rate and death rate
Net migrationDifference between immigration and emigration
Dependency ratioThe ratio of non-working (children + elderly) to working-age population

The Birth Rate

Long-Term Decline

  • In 1900, the birth rate was approximately 28.7 per 1,000; by 2020, it had fallen to approximately 10.0 per 1,000
  • The total fertility rate has fallen from around 4.0 children per woman in 1900 to approximately 1.6 today — below the replacement rate of 2.1
  • There were baby booms after both World Wars and in the 1960s, but the long-term trend is downward

Reasons for the Decline in Birth Rate

Changes in Women's Position:

  • Harper (2012): the most important factor is the changing position of women
  • Greater access to education and careers means women delay having children or have fewer
  • The contraceptive pill (available from 1961) gave women control over fertility for the first time
  • Legal changes: Equal Pay Act (1970), Sex Discrimination Act (1975), Abortion Act (1967) — expanded women's choices

Economic Factors:

  • Children have become an economic cost rather than an economic asset (unlike pre-industrial families where children contributed labour)
  • The cost of raising a child to age 18 is estimated at over £150,000 (Child Poverty Action Group)
  • Postman (1994) and Aries (1960): the development of a "child-centred" culture means parents invest more in fewer children

Declining Infant Mortality:

  • As infant mortality fell (from 154 per 1,000 in 1900 to under 4 per 1,000 today), parents no longer needed to have many children to ensure some survived
  • Tranter (1996): declining IMR led to a decline in birth rate because parents could be confident their children would survive

Secularisation:

  • Decline in religious influence has reduced opposition to contraception and smaller families
  • The Catholic Church's opposition to artificial contraception has become less influential even among Catholics

Changing Values:

  • Beck and Beck-Gernsheim (1995): in late modernity, individuals prioritise self-fulfilment — having children is a choice, not an obligation
  • Giddens (1992): relationships based on the "pure relationship" do not necessarily require children

Effects of the Decline in Birth Rate

  • Smaller families: the average household size has fallen from 4.6 in 1900 to 2.4 today
  • More child-centred families: fewer children means each child receives more parental time, attention, and resources
  • Dependency ratio: fewer young dependants, but combined with an ageing population, the overall dependency ratio may not improve
  • Women's participation: lower birth rates have enabled more women to enter and remain in the workforce
  • Public services: fewer school places needed, but greater demand for elderly care

The Death Rate

Long-Term Decline

  • The death rate has fallen from approximately 19 per 1,000 in 1900 to approximately 9 per 1,000 today
  • Life expectancy has risen dramatically:
  • In 1900: approximately 50 years for men, 57 for women
  • Today: approximately 79 years for men, 83 for women
  • The biggest improvements occurred in the first half of the 20th century

Reasons for the Decline in Death Rate

Improved Nutrition:

  • McKeown (1972): argued that improved nutrition was the most important reason for the decline in death rates in the 19th and early 20th centuries
  • Better diet increased resistance to infectious diseases
  • Evaluation: other factors (sanitation, medicine) also contributed — McKeown may overemphasise nutrition

Medical Advances:

  • Antibiotics (penicillin from 1940s), vaccinations (smallpox, TB, polio), and improved surgery reduced deaths from infectious and chronic diseases
  • The NHS (founded 1948) made healthcare free at the point of use
  • However, medical advances had their greatest impact AFTER the major decline in death rates had already begun — public health measures (clean water, sewerage) may have been more important initially

Public Health Improvements:

  • Clean water supplies, sewerage systems, and refuse collection from the late 19th century dramatically reduced deaths from waterborne diseases (cholera, typhoid)
  • Public Health Acts (1848, 1875) compelled local authorities to provide sanitation
  • Housing improvements, smoke-free zones, and workplace health and safety legislation

Decline in Dangerous Occupations:

  • The shift from manual/industrial work to service-sector employment has reduced workplace deaths and injuries

Lifestyle Changes:

  • Declining smoking rates (from 80% of men in the 1950s to under 15% today) have reduced heart disease and cancer deaths
  • Better health awareness, screening programmes, and health education

Class, Gender, and Regional Inequalities in Death

  • Marmot Review (2010): life expectancy varies by up to 20 years between the richest and poorest areas
  • Men in the most deprived areas live on average 9 years less than men in the least deprived areas
  • Women still live longer than men (approximately 4 years), though the gap is narrowing
  • Black Report (1980): identified four explanations for class inequalities in health — artefact, natural/social selection, cultural/behavioural, and structural/material. The report concluded that material deprivation was the primary cause

The Ageing Population

Key Facts

  • The UK population is ageing: the proportion of people aged 65+ has risen from 5% in 1900 to approximately 19% today
  • By 2050, it is projected that approximately 25% of the population will be 65+
  • The old-old population (85+) is the fastest-growing age group
  • There are now more people aged 65+ than under 16 in the UK for the first time

Causes

  • Declining death rate and increased life expectancy: people are living longer
  • Declining birth rate: fewer young people entering the population
  • Baby boom cohorts (1940s, 1960s) are now reaching retirement age

Effects on Society and Social Policy

The Dependency Ratio:

  • An ageing population increases the dependency ratio — fewer working-age people supporting more dependants
  • This puts pressure on the working population to fund pensions, healthcare, and social care through taxation
  • Hirsch (2005): the cost of providing for the elderly is a "demographic time bomb"

Healthcare and Social Care:

  • Older people are the heaviest users of NHS services
  • The demand for social care (home care, residential care) is increasing faster than funding
  • Griffiths Report (1988): advocated community care — caring for the elderly in their own homes rather than in institutions
  • In practice, informal carers (predominantly women — daughters and daughters-in-law) carry much of the burden — an estimated 6.5 million unpaid carers in the UK

Pensions:

  • The state pension age has been raised (to 66, rising to 67 by 2028, potentially 68 by 2046)
  • Many elderly people live in poverty — especially women, who are less likely to have adequate private pensions due to broken employment histories
  • Townsend (1979) — The Structured Dependency of the Elderly: argued that poverty in old age is created by social policies (forced retirement, inadequate pensions) rather than being an inevitable feature of ageing

One-Person Households:

  • The ageing population has contributed to the rise in one-person households, particularly among elderly women (who outlive male partners)
  • This increases demand for housing and social services

Sociological Perspectives on Ageing

Functionalism (Cumming and Henry, 1961 — Disengagement Theory):

  • Ageing involves a mutual withdrawal between the individual and society
  • This is functional: it allows younger workers to take over roles
  • Evaluation: widely criticised as justifying the neglect of elderly people

Political Economy of Old Age (Marxist):

  • Townsend (1981) and Walker (1980): old age is a period of structured dependency created by capitalism
  • Compulsory retirement, low pensions, and ageism force the elderly into dependency
  • Old age is not naturally a period of decline — it is made so by social structures

Postmodernism:

  • Old age is becoming more diverse — some elderly people are affluent, active, and healthy (the "third age"), while others are poor and isolated
  • The category "elderly" is too broad to be meaningful — it spans a 30+ year age range

Exam Tip

Demographic questions at A-Level require you to explain causes and effects of trends, not just describe them. Link demographic changes to family diversity (e.g., ageing population → more one-person households), gender inequality (women as unpaid carers), and social policy (pension reform, care funding). Use specific statistics and dates for AO2 credit.
