Demography Flashcards
How does a population increase? And decrease
Births and immigration, Deaths and emigration (natural change = number of births - number of deaths) (Net migration is the amount of people immigrants- emigrants)
How has the U.K population changed?
From 37million in 1901 to 65million today by 2031 the population should be 71 million
What Are The two methods of measuring births?
Birth rate, number of live births per 1000 people of the population per year and Total fertility rate is the average amount of children per women
Describe the trends in birth rate
There has been a long term decline in birth rate, from 29 in 1901 to 12.2 in 2014 a 60% decline! However it has not been a straight forward decline as there have been baby booms after world war 2, in the 60s, 80s and a small increase after 2001 abruptly stopped after the global economic crash of 2008
Describe the changes in fertility rate
In the 1960s women had an average of 2.95 declining to an all time low of 1.63 in 2001 before rising slightly to around 1.9 today
What are 4 reasons for a falling birth rate?
Changing position of women, fall in infant mortality rate, children as a economic liability and child centeredness
How have changes in the position of women lead to a falling birth rate?
Increased educational opportunities for women, changes in attitude to women’s role and family life, easier access to divorce and less marriage expectations and access to abortion and contraception , always explain how they lead to fall in birth rate!
How has a fall in the infant mortality rate lead to a fall in birth rate?
The infant mortality rate is the number of infants who die before their first birthday per 1000 babies born alive per year, it has fallen greatly from 154 in 1900 to 4 in 2016, this is because of improved housing, sanitation and the NHS, if having a child becomes less of a gamble and a chance then mothers will have less as they don’t need to ensure some survive
How has children as an economic liability caused a fall in birth rates?
Until around the 1880s when compulsory education was introduced, children were economic assets as they worked and contributed to family income however they are now an economic liability as laws banning child labour and changing norms of children have meant that children are economically dependent for much longer and as a result of this families may be unable to have large families due to the cost
How has child centredness lead to falling birth rates?
As the idea and social construction of childhood has grown and children have become arguably more loved, parents concerns have changed from quantity also linking back to economic assets etc. To economic to quality ensuring that their children are brought up correctly and lavishly in a competitive world
What are some of the effects of a falling birth rate?
+Women are more able to have a long successful career and create a perfectly dual income couple
+The dependency ratio (the ratio between working population and non working dependents such as elderly and young people falls for young people reducing the burden of dependency but rises for old people as the decreased young working population must support an ageing population which can distract from careers
+Schools may close and there will be less people to pay for and work for public services supporting an ageing population which could cause a catastrophic problem for the nation
What do death trends look like in the U.K?
Death rates have been fairly stable since 1900 at around 600,000 people per year but the population has increased exponentially since then but the number of deaths has remained stable but the death rate has decreased showing an ageing population , the death rate rose during the world wars but ever since has gradually decreased
What are some of the reasons for a fall in death rates?
Up until the 1970s 3/4 of the decline in deaths rates was because of a fall in deaths via infectious diseases such as TB, measles or smallpox however since the 1970s other factors have made a larger impact such as:
Improved nutrition, according to McKeown (1972) almost a half of the reduction in death rates was due to better diet although in an NHS report from 2010 Obesity and related illness now account for half of all uk deaths showing that diet is becoming a problem once again.
Medical improvements, since the 1950s vaccines, antibiotics and better services through the creation of the NHS (1949) have decreased the death rate
Occupational changes, less dangerous and hazardous jobs such as mining have decreased due to globalisation
And health education has became commonplace
And war has decreased over time
Although medical takes the credit, social and economic factors have also helped
What are some of the changes in life expectancy?
Life expectancy is how long a person born in a certain years average life expectancy is, For babies born in 1900 it was 59 for males and 57 for females but for babies born in 2013 it was 90.7 for males and 94 for females, the gap between women and men has dropped over time due to a fall in manufacturing jobs and a rise in services jobs for both men and women
How does a falling infant mortality rate raise life expectancies?
As falling IMR have drooped from 154 in 1900 to 4 now it has stopped dragging down the life expectancy as a whole resulting in a rising life expectancy
