What is demography?
Demography is the study of human populations. It studies the size, composition and structure which make up the general components.
What is the crude death rate?
Crude birth rate indicates the number of live births occurring during the year, per 1,000 population estimated at midyear.
What are the 4 factors that influence fertility?
- Proportion of women who are permanently or temporarily unable to conceive (infecund).
- Proportion of women either married or in a sexual union.
- Percentage of women using contraception.
- Level of induced abortion
What proportion of women do South Korea have using contraception?
82% (2019) use contraception
In 2018, what did the USA TFR drop too?
1.7, it was the lowest ever recorded
What are the features of stage 1 DTM?
Stage 1: Young population with high births and mortality rates. Minimal population change (>0.5%).
What are the features of stage 2 DTM?
Stage 2: Mortality rate decreases but birth still high. Population growth occurs.
What are the features of stage 3 DTM?
Stage 3: Decline in both birth and mortality rates, so continues population growth
What are the features of the stage 4 DTM?
Stage 4: Low fertility and mortality causes stable population size but with a high proportion of older.
What are the 4 stages of the DTM called?
- Pre-modern
- Urban/Industrialising
- Mature Industrial
- Post industrial
What are 4 reasons for the declining fertility rates?
- Child centredness
- Economic Impacts
- Psycological Impact
- Decline in infant mortality
What are 4 critiques of the DTM?
- It’s a description rather than a theory.
- Assumes population changes due to modernisation and industrialisation.
- Doesn’t acknowledge variations in timing or speed of the stages.
- Doesn’t acknowledge level of application over time.
What was life expectancy in 1800?
29
What was life expectancy in 1950?
60 in Western nations, 29-41 in African and Asian nations
What are the 5 main factors influencing life expectancy?
- Medical care/technology
- Life style (smoking, diet, alcohol and risky behaviour).
- Social networks (the risk of loneliness).
- Genes
- Stressors/disadvantages (socio-economic disadvantage).
What is it called when deaths increase in the middle age?
Deaths of despair
1. Soviet Union collapse led to men dying.
2. UK/USA have high male suicide rates.
What are 4 reasons which influence variation between male and female death rates?
- Anatomical and physiological reasons.
- The extra X chromosome.
- Oestrogens (which cause anti-inflammatory, Vaso-protective and enhance immune defences, where as progesterone has immunosuppressive effects an increases the mortality risk for certain diseases)
- Male excess mortality exists in most animal species.
What are 4 behavioural and social factors which may influence variation in death rates between men and women?
- More smoking and alcohol consumption among men.
- Men are more risk taking.
- Men subjected to greater health risks at work due to gendered occupations, And are generally more susceptible to stress.
- Women are more likely consult a doctor when noticing symptoms.
What proportion of babies born in 2015 will live to 100?
1/3
How many centurions live in the UK as of 2016?
14,910 people aged 100+ (centenarians) in the UK in 2016
How many oldest-olds (85+) live in England Wales as of 2011?
1.25million
What proportion of the UK population do 90+ make up?
1%
What is the epidemiological transition?
The epidemiology transition is the characteristic shift in the disease pattern of a population as mortality falls during the demographic transition. Infectious diseases decline while chronic degenerative disease increases in commonality, which causes gradual shift in age pattern.
Why were more men impacted by the Spanish flu?
War and work.
