Demography - 2.5 Flashcards
Define Demography
Study of population and it’s characteristics.
What 4 Factors is Population Growth affected by?
> Births & Immigration + pop
> Deaths & Emigration - pop
Define Natural Change
NO of Births - NO of Deaths
Define Net Migration
NO of ppl immigrating into a country - NO emigrating from it.
Explain the Trend in UK Pop
> Risen est 1900.
> Growth due to natural change > net migration.
What are the 2 Measures of Birth
> Birth Rate (BR)
> Total Fertility Rate (TFR)
Define Birth Rate
NO of live births per 1K of population per year.
What is the Trend in Birth Rate?
- Declining est 1900
- Despite Baby Booms after 2 WWW’s & 60’s
Define Total Fertility Rate
- Avg NO of kids a woman has in her fertile years (15-44).
Outline the Trend in Fertility Rate
- Declining
- TFR affects family size
What do the Changes in Birth and Fertility Rate Reflect?
> More women remaining childless
> Women have kids later
Define Infant Mortality Rates
NO of infants who die before 1st birthday per 1K babies born per yr.
Birth Key Sociologists
> Harper (IMR) - Improved Living Standards (ILS)
> Giddens (Contraception)
Reasons for Decline in Birth Rate
> Improved Living Standards (ILS)
Contraception (Giddens)
Changes in Position of Kids
Explain how ILS leads to a fall in Birth Rate
- Wealthier the country, lower the BR
- Eco Growth & ILS mean couples have fewer kids.
- As ILS means better housing, diet, education & medical care.
- Harper says reduced IMR means couples have less ‘replacement babies’ to replace those who die in infancy.
A03 Births Key Sociologist
> Functionalist (ILS) - Structural Differentiation
Explain the Functionalist view of Structural Differentiation being the reason for fall in Births opposed to ILS?
> State institutions take over functions of family.
> Couples don’t need kids to look after them in old age as other institutions do this, so ppl have fewer children.
Explain how Giddens states Contraception has led to a fall in Birth Rate
- Led to ‘plastic sexuality’ = sex becomes detached from reproduction.
- Pill gave women control of reproduction, so they can choose when to have kids.
- IVF mean women can delay having kids later, so have less
Explain the Criticism of Giddens idea that Contraception has led to a fall in BR
> IVF expensive, so not available for all couples.
> No correlation vs Pill and decline in BR, in fact Baby Boom in 60s came after pill’s invention.
Explain the Idea of Changes in the Role of Women being the reason for fall in Births opposed to Contraception?
- More girls in paid employment, so reject domestic role, as career now priority
- Some opting to be childless altogether.
Explain how Changes in the Positions of Kids leads to a fall in Birth Rate
- Kids were eco asset to families as they could work.
- Complusory skl increases dependency, so now eco liability, so have less kids
- Socities child centered so move from ‘quantity’ to ‘quality’, ppl have less kids, giving them more attention and resources.
Explain the Idea of Geographical Mobility being the reason for fall in Births opposed to Changes in the Position of Kids?
- Modern labour force needs to be very mobile
- Incentivizes ppl to have small families as it’s easier to pack up and move elsewhere.
What 4 things does Changes in Fertility affect?
> Family
Dependency Ratio
Lonely
Public Services & Policies
Explain how Changes in Fertility affect the Family?
- As families are smaller, women can now go work creating DEF.
- Wealthy couples can still have large families, as they can afford childcare
Explain how Changes in Fertility affect the Dependency Ratio?
- Fall in NO of kids reduces burden on Working Population.
- But fewer ppl entering workforce w/ more ppl retiring.
- Leads to more taxation on working pop to support retired majority.
Explain how Changes in Fertility affect kids in terms of Loneliness?
- Lower BR means childhood’s lonelier for only kids
- More childless adults means less ppl giving kids a voice
- But could mean kids will be more valued
Explain how Changes in Fertility affect Public Services and Policies?
- Fewer skls and child health services needed, less needs to be spent on maternity & paternity leave
- Instead of fewer skls, gov may opt for smaller class sizes.
Explain the Trend in the NO of deaths
Fallen
Define Death Rate (DR)
NO of deaths per 1K of population per yr.
Deaths Key Sociologists
> McKeown (Improved Nutrition) > Tranter (Fall in NO of deaths from Infectious Diseases (ID) > Harper (Obesity) > Harper (Radical Longetivity) > Walker (LE in Poor vs Rich Areas)
Outline Factors related to ILS leading to a fall in Deaths
- Improved Nutrition
- Better Quality Housing
- More income
- Smaller Family Sizes
Explain how Improved Nutrition has lead to a fall in DR, according to McKeown?
- Better diet, reduced NO of deaths from TB
- It increased resistance to ID & survival chances
Explain how Better Quality Housing has lead to a fall in DR
- Better heating to keep warm during winter months, reduces NO of colds etc.
- Less damp so less illness, better housing means less deaths from accidents.
Explain how Small Famliy Sizes has lead to a fall in DR
Better access to contraception, ppl have fewer kids, reduces chances of disease transmission.
Explain how More Income has lead to a fall in DR
- More cash to spend on medicines, food, water, heating etc.
- But also more taxation = more money for public health services.
4 Criticisms of Improved Living Standards
> Doesn’t tells us why girls who get smaller share of food supply, lived longer than men.
> Not all benefit equally, MC have longer LE than WC who suffer from poverty
> Obesity now serious problem – more food don’t mean better nutrition.
> Deaths from measles & infant diarrhoea, rose during improved diet.
Outline Factors related to Medical Improvements leading to a fall in Deaths
> Fall in NO of deaths from Infectious Diseases (ID) (Tranter)
Medical Advances
Obesity (Harper)
Explain Tranter’s findings on Fall in NO of deaths from infectious diseases, in relation to reasons for Decline in DR
- Due to fall in deaths from ID e.g. measles
- Decline in DR occurred among kids
. - Heart disease & cancer overtaken ID
- Vaccines
Explain Medical Advances in relation to reasons for Decline in DR
- Fell due to e.g. vaccinations, antibiotics, blood transfusion, & creation of NHS.
- Vital in reducing NO of deaths from ‘diseases of affluence’ e.g. heart disease & cancer.
Explain how Obesity has lead to a fall in DR, according to Harper?
- Obesity replaced smoking as new lifestyle epidemic.
- But deaths are low due to drug therapies.
- We’re adopting “American” health culture w/ unhealthy lifestyles, but long lives achieved w/ costly medication.
Criticisms of Medical Improvements (Tranter)
> Vaccinations aren’t entirely effective, seen in COVID-19 pandemic, new variants or strains, may appear which vaccinations aren’t immune too.
> MC ppl have access to private health care, more efficient > public health services for WC.
Outline Social Factors and Policies leading to a fall in Deaths
> Public Health Measures
> Other Social Changes
