Total population small, 6 million in 1700. Poor diet and hygiene, wars and diseases caused high death rate. Birth rate also high though.

A
Population grew quickly due to improvements in farming and medicine so disease and starvation reduced. Birth rate was high and rapid economical growth
23
Q

Ageing population and by 2040 1/4 of uk will be over 65. Population may begin to decline if birth rate becomes lower than death rate
26
Why is the DTM useful
Can give a generalised idea of how a population can change over time. Easy to compare and can forecast how population is likely to change which allows government to decide on policies eg immigration law or one child whatsit
27
What are some limitations of the DTM
Population in different countries may change differently due to social things, eg catholic church condemns contraception. Original DTM didn't have stage 5 but it had to be added. Doesn't take into account migration which has a large effect on population change
28
What three things may affect a population so it no longer fits the DTM
Population policies, infectious disease or civil war
29
What does the dependency ratio show
The proportion of the population that has to be supported by the working population (15-64).
30
How is the dependency ratio calculated
Young (under 15) + old (over 65) divided by the working age population (15-64
31
What are 4 social impacts of an ageing population non specifically
Increased pressure on public services eg hospices. Unequal distribution of older people so areas may not have facilities for younger people eg child are. Reduced population growth or decline. Longer working life as state pension is low due to all the retired people like my dad
32
What are 3 economic impacts of an ageing population
Reduced work force so slower growth. Increased taxes to provide for services and pensions. Good for economy as elderly have savings to spend on knitting equipment and buying their grandchildren presents or something
33
What are 2 social impacts of a youthful population
Increased pressure on public services such as childcare or schools. Rapid population growth which may lead to overpopulation.
34
What are 2 economic impacts of a youthful population
Unemployment as not enough jobs for young people. Increased poverty as more young people born into poverty and aren't educated as they have to work so can't break out of poverty
35
What's a political impact of an ageing population
Elderly issues will be important to voters eg changes to pensions
36
What's a political impact of a youthful population
Youth issues will be important eg student loans and childcare provision
37
What four things can be done to manage ageing populations
Encouraging larger families. Raising retirement age. Encouraging immigration of working age people. Increasing healthcare provision
38
How does encouraging larger families help to manage the ageing population
Eg Swedish government give both parents 18 months paid leave. Should result in a larger working population in future which can provide more taxes for better services
39
How does raising the retirement age manage an ageing population
Working population larger so more people contribute to pension funds for longer and will claim pension for less time
40
How does increasing the immigration of working age people help a country manage an ageing population
I'm recent years Japan increased number of foreign workers as aren't enough working age Japanese people for aoonthe jobs. This increases the working population which supports the ageing population by paying taxes towards pensions and services
41
How does increasing health care provision help to manage an ageing population
Helps to ease the problem of poor health in the elderly as large numbers of older people put pressure on the health care systems
42
What are 4 strategies for managing a youthful population
Controlling birth rate. Limiting immigration of younger people. Encouraging use of contraception. Increasing childcare provision.
43
How does controlling birth rates help to manage a youthful population
Eg china introduced one child policy in 1979 and this is thought to have prevented 300 million births. Slows further population growth.
44
How does limiting the immigration of younger people help to manage a youthful population
Means birth rates aren't made higher by immigrants having children
45
How does encouraging the use of contraception manage a youthful population
Governments can offer free sex ed like that interpretive dance with mr walker. Free contraception.
46
How does increasing childcare provision help to manage a youthful population
Countries can invest in making it more accessible so parents can work. Helps to manage some of the problems caused by a youthful population.
47
What is sustainable development
Developing to meet the needs of the current population without hindering the ability of people in the future to meet their needs. Involves not damaging the environment or altering it in an irreversible way or depleting all of a resource. Problem is the populations needs all need to be met in a sustainable way.
48
Why does the uk have an ageing population and how many people are old
People over 65 will be 25% of population by 2040. Increasing life expectancy. Baby booms in 40s and 60s. Falling birth rate so higher proportion of older people
49
What problems does an ageing population impose on the uk
Pressure on pension system - only 60% population are of working age to pay takes for this. More elderly people living in poverty as working population isn't big enough to afford a higher state pension. Pressure on health service greater.
50
How did increasing the age of retirement in the uk help to combat our ageing population
Will be raised to 68 for everyone by 2050. Currently 65 for men and 60 for women. Means people have to work for longer do there's a larger working population
51
How does encouraging immigration of working class people help the uks ageing population
Around 80% immigrants to uk are under 34. Increases size of working population. Unlimited immigration from countries in the eu eg Poland
52
How does the uk government encourage people to have children
New uk pension proposals mean women won't lose out on any of their state pension if thru take career breaks to have children
53
How does increasing retirement age contribute to sustainable development
Doesn't increase the population but more jobs may be needed as people work for longer which may reduce sustainable development unless the jobs come in a sustainable way such as working on wind farms etc
54
How does allowing immigration contribute to sustainable development
Only sustainable if needs of new people met in a sustainable way eg increased energy demand could be met by increasing renewable energy sources
55
What's the population of Uganda like
50% population under 15. Youthful population. Only 3% over 65.
56
Why is ugandas population youthful
High birth rate of 50 per 1000 people and total fertility rate of 7 children. Low life expectancy of 52 years so proportion made up of young people is high
57
What problems are caused by Ugandas youthful population
Pressure on health service, 6000 women die in childbirth each year. Pressure will be even greater when youthful population reach reproductive age. Overpopulation. Unemployment will rise as not enough jobs for everybody and poverty will increase
58
What strategies have Uganda used to manage its youthful population
Encouraging use of contraceptives, only 25% of married women use contraceptives. Its free but not very widely available. However birth rate is still increasing so this suggests this hasn't worked. Should reduce birth rate and help prevent overpopulation from getting worse so country can focus on sustainable development for the current population

72
What's a bendy triangle population pyramid
Stage 1 high birth rates and high death rates low life expectancy

High numbers of immigrants can change the culture by bringing existing culture. If they Don't integrate can be segregation.
82
How can population change or migration affect age structure of areas
Rural areas have ageing populations as young people leave and retired people more there. This changes the provison of schools eg rural schools may have to close
83
How can population Change or migration affect unemployment
If a lot of people move to an area and there isn't enough jobs available then unemployment is high. In rural areas people moving away could lead to a lack of workers
