geography Flashcards
death rate
the speed at which people in an area die. Measured by the number of deaths for every 1000 adults in population
birth rate
the speed at which people in an area are born. Measured by babies born to 1000 adults
natural increase
when the birth rate is higher than the death rate. This causes the population of an area to increase naturally. This can be seen in LICs
natural decrease
when the death rate is higher than the birth rate in an area. This causes the population to decrease naturally. This can be seen in advanced HICs like Japan
migration
the movement of people from one area to another to live and work. For example when a young adult moves from wigan to London in search of work
population explosion
a sudden and rapid growth in the population of an area. This can be caused by natural increase, in-migration or a combination of both
population policy
a law passed by a government to reduce the birth rate. For example chinas one child policy
population density
the number of people in a certain area. Populations can be dense (tightly packed) or sparse (spaced out )
what is stage 5 of the demographic transition model
shows a declining population, birth rate lower than death rate but population increases
happening to japan naturally and now china in 30 years due to one child policy
ageing population
not many children in schools
name 2 good things about chinas one child policy
policy prevented 400 million births
more space in chinese schools for girls as there was less
name 2 bad things about chinas one child policy
huge imbalance in boys and girls births
if women got pregnant for the second time the they would have major consequences
