Terms in this set (...)

when a country does not have the resources to give all its people an adequate standard of living
population explosion
the dramatic rise in the world population which took place during the last two centuries
are the less economically developed countries
are the more economically developed countries
pro-natalist policies
strategies designed to stimulate a country's population growth by increasing its fertility rate
fertility rate
the average number of children women have in their lifetime is..
death rate
the average number of deaths in a year (for every 1000 people)
birth rate
the average number of live births in a year (for every 1000 people)
economic reasons for population explosion
children can be an important source of income. In the poorest countries, every contribution, however small, is vital tot he family budget. A child's income can mean the difference between starvation and survival for a family
care for elderly reasons for population explosion
older children can support the family by looking after elderly parents, or parents whose working lives are cut short by illness and accidents. The children may be the only support in countries that don't provide pensions or facilities for the sick and elderly
infant mortality reasons for population explosion
Parents want to make sure that at least some of their children will survive and become adults. In poor societies, where medical facilities are limited, there is a high infant mortality rate. Having a large family provides security against the problems of old age
life expectancy reasons for population explosion
People are now living longer because of improved medical knowledge and treatment. Better farming methods have increased crop yields so there is more food and a more nutritious diet
life expectancy
the average number of years people can expect to live
growth rate
the difference between the birth rate and the death rate
infant mortality rate
the proportion of children dying at birth or before their first birthday is..
if the number of people living in an area is fewer than the number that can be supported by the resources in that area
too many people, too few resources
a lack of clean water, droughts, loss of jobs, clearing of forested areas, natural disasters
a lack of clean water
It can force people to use polluted sources and possibly fall ill with diseases many of which are life-threatening, especially for the very young and old
Liberia's literacy rate is
loss of jobs
When valuable natural resources become exhausted, workers are no longer needed and will not be able to support their families
They are becoming more frequent and severe due to climate change. They increase the risk of starvation in already over-populated countries
population growth
when there is rapid population growth, or an increase in immigrants, a country may be less able to provide for its people
clearing of forested areas
Can result in families not having the fuel they need for cooking, heating and washing
natural disasters

People's basic needs
shelter, water, food and clothing

Liberia's percentage of all Liberians below 25 years of age
Liberia's birth rate
36 per 1000 people

Canada has a land area
14 325 times larger than Singapore
Canada is under-populated
because the infant mortality rate is very low and life expectancy is high
Tanzania Infant mortality rate

black death
Mid-14th century, which we now know was spread by rat-born fleas, killed over 75 million people in Europe. It had significant impact on the global population at that time
spanish flu
1918-20 killed about 75 million people. It was probably particularly deadly because many people had been weakened by the effects of the First World War (1914-18)
Kills at least 1 million people every year in tropical countries, where breeding conditions for mosquitoes are ideal. One in every five childhood deaths in Africa is due to this disease.
