Demography
Population
static-Until 1750 stable(728m),estimation for 2000- 6200m.Estimated final
pop.-10 billions
People
growing older,fewer children&thus workforce,more pensions,economy less
productive
More
boys born
When
population grows,more labour available&market is bigger
The
projected population ,need to be taken care very seriously,you can't predict
e.g.when new pill is invented
TR Malthus(1766-1834)
Wrote
that population grows exponentially whereas other factors of productions
linearly
Predicted
that the world population would grow until a war&then decline&then
start all over.Optimum level: when most people are starving to death=
subsistence equilibrium.This didn't happen in UK,because people went to
Australia,technology improved(more food)and family limitations
Factors affecting the growth of population
1. Birth rate
attitude
to artificial birth control
social&religious
attitudes to birth control
whether
the women want career or not
sex
ratio
number
marriages
age of
marriage&the size of families
2. Death rate
medical
care
food
public
health(clean drinking water)
housing
preventive
medicine(injections,vaccination)
war
3. Migration
Emigration
Immigration
Infant
morality rate declines-impr.in medicine,birth rate,parents want to enjoy high
life standard,family limitation,children not investment
As the
distribution of the population changes,demand changes,Such changes require
factors of production,not easy to find,can't convert schools to
hospitals,&people don't want to change work place
If the
dependent age group grows,there is a greater burden on the working
population(+tax),Changes in capital market(people live in savings)
Working
population(15-65)-All in civilian employment + army + registered unemployment
Recently
increase-Numbers of females working is increased(decl.of manufacture,more jobs
for women),Increasing self-employment(unempl.start relied to
savings,Gov.help),different statistics
The UK population
1. Growth since 1801&changes since World
War II
Fist measurement
was in 1801(10.5m)then population increased rapidly 12% per decade till
1870,because death rate fell.At 1870 people started to limit their
families.After that has been fluctuating 5-1% per decade.There was a baby-boom
from 1945-1965,because people started to get married early.After 1970ies
population fell,because no.of marriages fell.Population was 56m in
1991&estimation for 2001 is 55.5m
2. Age distribution
More
pensioners,less school-leavers,more people go first time to school,greater
dependency rate
3. Sex distribution
Births
in UK are fairly equal(105:100).More women in retirement(3:2)
4. Geographical distribution
Overall
density: 238persons/km2,one of the highest.Despite,there are great regional
variances.Most live in south,people move from North-England&Scotland to
South & East-England.Population is urban,but moving more to sub-urban
5. Occupational distribution
Working
force-between 16-65(60),includes unemployed.The percentage of women working is
the highest in developed countries.Workforce was 48% divide between industries:
a.primary-extraction
+ fishing,decreases,UK extremely low %age(deindustrialisation)
b.secondary-manufacture,was
North-Sea oil
c.tertiary-services(62%),in
UK now tourism
6. Likely future developments
Financial&professional
services,movement to North again(cheaper,no need to be in London to do
business).Technical improvements have to continue,otherwise the population
grows too large(diminishing returns).The optimum population differs from
country to country&is measured by GNP per head.Too much population is also
bad for environment
UK is
not yet over-populated,but may well become so in near future
UK has
higher birth rate,divorce rate,single mothers in Europe
