Demographic Trends Flashcards
(35 cards)
What is meant by demography?
The study of population
Includes looking t changes to: birth/ death rates, life expectancy etc.
Define birth rate
The number of live births per 1,000 of the population per year
Define total fertility rate
The average number of children 1 woman will have between the ages of 15-44
What is the average total fertility rate?
1.9
Define death rate
The number of deaths per 1,000 of the population per year
Define infant mortality rate (IMR)
The number f children dying before their 1st birthday per 1,000 live births per year
What is the dependency ratio?
The proportion of dependents per 100 working-age population
Define life expectancy
The average number of years that a person can be expected to live
Define migration
Moving to another country for a period of at least a year
Define immigration
Entering another country for a period of at least a year, so that it becomes your usual place of residence
Define emigration
Leaving your usual country of residence for at least a year, to live in another country
Define net migration
The difference between the no. of immigrants coming into a country + the no. of emigrants leaving a country in a year
Natural change
Changes in the size of the population due to changes in the no. of births + deaths, including migration
Define globalisation
The way in which the world is becoming increasingly interconnected, causing time and space to seem compressed
What is an ageing population?
When people are living longer so the average age of the population is increasing
What is happening to the BR in the UK?
What was it in 1901 compared to 2012?
BR = decreasing
29 vs 12.2
What is happening to the TFR in the UK?
What was it in 1901 compared to 2012?
TFR = decreasing
3.5 vs 1.9
What is happening to the DR in the UK?
What was it in 1901 compared to 2012?
DR = decreasing
18.4 vs 9.3
What is happening to the IMR in the UK?
What was it in 1901 compared to 2012?
IMR = decreasing
142 vs 4
What is happening to the life expectancy in the UK?
What was it in 1901 compared to 2012?
Life expectancy = increasing
45 vs 80
What is happening to the dependency ratio in the UK?
What was it in 1901 compared to 2012?
Dependency ratio = increasing
34 vs 53
Give 4 causes of decreasing BR + fertility rates since 1900
- Changes in gender roles (W delay, contraception, abortion, EPA 1970, education)
- Falling IMR (higher living standards, health care etc)
- Increased cost of child-rearing (school = extended, more child-centred - have less to give them the best)
- Changing attitudes (other family types more accepted, Beck + Gernsheim: individualisation)
Describes Beck + Gernscheim’s process of individualisation
People have become more concerned with their own needs
No longer have to follow traditional norms but can make their on decisions e.g about marriage + having children
How could you explain the slight increase in BR recently?
2
- Migration patterns (people moving into UK)
Migrants tend to be young adults (child-bearing age) + average migrant families = bigger than non-migrants - Older W having children through reproductive technology e.g. IVF
