Demography - 2.5 Flashcards
Demography
Study of populations characteristics.
4 Factors affecting Population Growth
> Births & Immigration + pop
> Deaths & Emigration - pop
Natural Change (NC)
NO of Births - NO of Deaths
Net Migration (NM)
NO of ppl immigrating into a country - NO emigrating from it.
Trend in UK Pop
>
- est 1900, due to NC > NM.
2 Measures of Birth
> Birth Rate (BR)
> Total Fertility Rate (TFR)
Birth Rate
NO of live births per 1K of population per year.
Trend in BR
- est 1900, despite Baby Booms after 2 WWW’s & 60’s
TFR
> Avg NO of kids F has in her fertile years (15-44).
Trend in TFR & Reasons
- & affects family size
>
- F childless or having kids later
IMR( infant mortality rate)
NO of infants dying before 1 per 1K babies born per yr.
Birth (KS)
> Harper (ILS)
> Giddens (Contraception)
Reasons 4 - BR
> Improved Living Standards (ILS)
Contraception (Giddens)
Changes in Position of Kids & F
Geographical Mobility
Harper (Improved Living Standards (ILS) & Falling BR) - Reasons 4 - BR
> Richer country - BR, ILS so ppl have less kids.
> ILS = + housing, diet, education & medical care.
>
- IMR so ppl have - ‘replacement babies’ 4 those who died in infancy
A03 ILS Births (KS)
> Functionalism (SD)
Functionalist (Structural Differentiation) - Criticisms of ILS
> State institutions do EF function, so don’t need kids 2 look after us in OAP
Contraception (Giddens) - Reasons 4 - BR
> Plastic sexuality’ = sex becomes detached from reproduction.
> Due to pill i.e. allows for + strategic family planning, IVF allows 4 delaying kids
General Criticisms of Giddens & Reasons 4 - BR
> IVF expensive, not 4 all
> Baby Boom in 60s came after pill’s invention
Changes in Position of Kids & F - Reasons 4 - BR
>
- F focused on career first or not interested @ all
> Kids were eco assets, but compulsory skl + dependency, cost +
> Child centeredness e.g. move from ‘quantity’ to ‘quality’
Geo Mobility - Reasons 4 - BR
> Modern labour force needs to be very mobile, incentive 4 smaller families e.g. easier to pack up & move elsewhere.
Implications of Changes in Fertility
> Family
Dependency Ratio
Lonely
Public Services & Policies
Family - Changes in Fertility
> Smaller. F can now go wrk creating DEF
> But wealthy couples can still have + kids e.g. can afford childcare
DR - Changes in Fertility
>
- kids reduces burden on wrking pop
> But - ppl entering workforce + ppl retiring = + tax on wrking pop supporting retired majority
Lonely - Implications of Changes in Fertility
> Childhood’s lonelier for only kids + childless adults = - ppl giving kids a voice
> But kids + valued
Public Services & Policies - Implications of Changes in Fertility
>
- skls & health services needed - spent on maternity leave
> Instead of - skls, gov may opt 4 smaller classes sizes
Trend of deaths
Fallen
Death Rate (DR)
NO of deaths per 1K of population per yr.
Deaths (KS)
> McKeown (Improved Nutrition)
> Tranter (Fall in NO of deaths from Infectious Diseases (ID)
> Harper (Obesity)
> Walker (LE in Poor vs Rich Areas)
ILS Factors leading to Fall in Deaths
> Improved Nutrition & + Income
> Better Quality Housing & Smaller Family Sizes
McKeown (Improved Nutrition) & Income - ILS Factors leading to Fall in Deaths
> Better diet, so - deaths from TB, + resistance to ID & survival chances
>
- income so + £ for medicines, food etc - but + taxation 4 NHS
