Demography (familes) Flashcards
Demography
Who makes up society
The study of statistics which illustrate the changing structure of human populations
Reasons to study demography
1) suggest policies to improve life for specific groups for example women
2) changes in society over time and look at the impact of changes over time for example birth rates
3) research issues experienced/faced by the groups
ways that a population can increase
1) increase in birth rate
2) increase in migration
Ways that a population can decrease
Death
Emigration ( people leaving)
Population trends
In Britain the population has increased over the past 100 years and continues to grow despite lower birth rates. Mainly due to natural change rather than net migration
Natural change
Is the number of births minus the numbers of death
Net migration
Number of immigrants minus the number of emigrants
Demography characteristics
Size- is the population small or large
Age structure- is the average age of the population rising or falling
Births- how many babies are born
Deaths-how many people die
Immigration-how many people enter the country from elsewhere
Emigration-how many people leave the country to live elsewhere
The dependancy ratio means the % of dependant people (not of working age)/ number of people. Of working age (economically active)
Dependancy ratio equation
Number of children(0-15) + number of pensioners (>65) ÷ number of working age (16-65)
For example a dependancy ratio of 1.2 means that for every 10 workers there are 12 people not of working age
