EQ1 Flashcards
What is population structure?
Population structure is the composition of the population of a country, region or area. The population structure of a place shows how it is divided up by males and females of different age groups.
Other components of population structure include life expectancy, family size and marital status
How much has the UK population increased between 1961 and 2011?
10.4 million
What is the rural-urban continuum?
The merging of a town or country. There is rarely either a physical or social divide between rural and urban areas. The urban built environment transitions into the urban-rural fringe, then into the farming and commuter zone which subsequently becomes the deep countryside and finally we see remote rural environments.
What are the external and internal factors that can cause a place to change?
Internal factors (originate from within): Cultural change; new employment opportunities; house prices; population change (growth, decline, aging); new transport links; closure/opening of industry External factors: investment from TNCs; Tourism; Migration; Trade
What are the reasons for population trends?
- Rising economic prosperity of London and the SE
- London has become a global hub of finance and business
- Hub of modern service industries
- Decline of manufacturing in NE and Midlands
- Collapse of traditional industry in Midlands and NE; e.g coal mining, iron and steel, ship building due to foreign competition and government policy of Margaret Thatcher
What is the population density of England compares to Scotland?
England - 406.5 people per km2
Scotland - 67.3 people per km 2
What are the factors affecting the population density of an area?
Planning- Planners control new developments. There have been greenbelts and other policies, particularly since WWII.
Socio economic status- The wealthier live in expensive housing areas which usually means they are detached/ semi-detached and therefore lower density. They will also avoid polluted areas (contributing to out-migration/ counter- urbanisation) so will be in the suburbs
Dwelling type and household size- High density blocks of flats will inevitably result in higher population densities. Terraced inner-city housing will also have higher densities
Physical factors- Flat areas allow for housing to be built so population densities will be higher in these areas
Functions (resident V non residential) - Lowered density if intermixed. Manufacturing areas means lower quality environments which will mean that fewer people will want to live there. More offices in the CBD means lower densities, higher prices and people pushed out.
What has driven the change in population structure - factors affecting birth rates.
Women’s status: 1928 vote, pay, age at marriage, delaying starting family - avg age 30.5 years
Reduction in family size: 1900 = 4.6 , 1950 = 2.2, 2015 = 1.7
Decline in infant mortality
Less religious influence
Contraception: Pill 1961
Abortion : 1967
Consumerism: burden of having children (£218,000 in 2012)
Recession (oil crisis 1970s)
What has driven the change in population structure - factors affecting death rates.
Healthcare: 1798 Small Pox vaccinations discovered. 1921 tetanus vaccine. 1848 Public health act. 1911 National insurance. NHS 1948
Hygiene, sanitation, health and safety: Indoor toilets, clean water supply, improved sewage system. Seatbelts and working conditions
Lifestyle, nutrition: Clean air act 1956, public smoking ban 2007
Globalisation: Dangerous jobs outsourced or done by machinery
How much has the UK’s median age increased between 1974 & 2014
From 33.9 to 40 (aging pop)
Describe the causes of change in UK urban areas 1960s - 2010
60s - Economic boom and industrialisation, Windrush
70s - Economic decline and deindustrialisation, demolition of older housing and building of new high rise flats
80s - Global recession, Competition from TNCs, redevelopment of the inner city, counter urbanisation
90s - Regeneration of CBDs, rise in migrants from middle east and Africa
00s - EU migration (2004 Expansion), 2007/8 crash demise of secondary and tertiary industries, competition from China
10’s - Rebranding and regeneration, reduction in funding to council, refugees from North Africa & Syria
Explain a systems view of population change
Inputs = Births and international immigration
Processes = Natural change & net migration
Outputs - Deaths and international emigration
What is Natural Change?
Number of Births - number of Deaths
What is Net Migration
Number of Immigrants - Emigrants
Arrivals exceed departures = net in-migration
Departures exceed arrivals = net out-migration
Why are you likely to find different numbers of males and females and ages in various places in the UK?
Some industries may be dominated by a particular gender (e.g offshore oil industry)
There are higher numbers of young male economic migrants
The elderly tend to locate in quieter locations (e.g Bournemouth); females tend to live longer than males
