population structure + characteristics varying from place to place over time and how past + present connections have shaped c/d characteristics (72 cards)
Demographic Transition Model
- populations expected to fall and rise ‘naturally’ due to inc developt
- populations will grow if the birth rate in + death rate dec
- has 4 stages
stage 1 of the demographic transition model
- high birth and death rate = total pop tends to be quite low + there isn’t much change in pop size.
- country is poorly developed = little wealth to spend on services such as health education
- most employmnt in primary industries (farming, mining) = intensive labour + low income.
- high birth rates due to lack of access to contraception, religious beliefs, lack of education
- high death rates due to lack of safe drinking water and sanitation, malnutrition, lack of access to
healthcare.
stage 2 of the demographic transition model
- death rates begin to dec while birth rate stays high = pop size starts to inc.
=> bc country becomes more developed = more money spent on hospitals + doctors. = less ppl dying. - basic knowledge of sanitation + transmission
- improvmts in farmin + mining practices (machinery) = red fatalities in work.
- secondary industry (manufacturing and production)
will also develop = offers high-paid + more secure jobs = income more consistent + SOL improves
stage 3 of the demographic transition model
- death rate continues to dec while birth rates dec = pop expands more rapidly
- women have more rights = more education + acces to contraception + family-planning advice
- focus placed on career may = women have childnre later + having less children or no children at all.
- move away from the primary industry = families dont need children to work on the land.
stage 4 of the demographic transition model
- birth rate + death rates are much lower and have plateaued.
- yet pop continues to inc for MEDC (more economicaly developed countries) as migrants from other countries are attracted to job opps + the better QOL provided.
- if controlled = mig can fill skills gaps + keep services and industries growing.
what does the DTM (demographic transition model) suggest?
suggests that there is a correlation between the development
of a country and its birth and death rates + any changes to these rates r gradual
- few exceptions ; UAE, whose sudden population growth is predominantly due to economic growth.
what does the DTM not consider?
- doesn’t consider countries whose development worsens; countries devastated by conflict or natural disaster.
e.g. Haiti EQ in 2010 ; still hasnt recovered + has experienced :
-> annual hurricane season = strom surges + sever winds + threatens temp shelters for the displaced.
-> cholera epidemic (9200 lives by 2016) = Artibonite River became contaminated w sewage.
-> 2 years after EQ, only half the rubble created was cleared.
UK population structure
- unevenly distributed due to condition of the land in the area.
- 84% live in england = low-lying hospitable land
- denser pop in major cities + concentrated along the south coast
- lowest pop density in rural areas
- rapid growth in areas of economic developt L+SE
- declining pop at scottish coast (up N) from lack of job opps + counter-urbanisation from deindustrialised cities e.g. bradford
reasons for UK pop changes
- birth rates inc
- birth rates dec
- death rates dec
- death rates inc
- inc in inward international migration.
birth rates inc due to :
- pop growth = no. of child-bearing ppl inc so rate of pop growth inc
- govt policy = maternity/paternity leave.
birth rates dec due to
- use of contraception = more widespread = free access thru NHS + sex ed in schools.
- religion = britains becoming less religious = more atheists = use contraception + get married later + feel less pressured to have children
- inc financial cost = choosing to have no/less children.
- advancement of women = more women wish to pursue a career = postpone having children
death rates dec due to
- advancement in medicine = diseases being eradicated + access to healthcare has improved
- immunisation to diseases
- clean water + sanitation = 96% ok uk households connected to main sewage system + 100% have access to clean water = red risk of water-borne diseases + diarrhoea.
death rate inc due to
-LIFESTYLE CHOICES
- smoking and alcohol consumpt = lung + liver cancer
- unbalanced diet = obesity + type 2.
inc in inward international migrations due to :
- political alliances esp with commonwealth countries.
- lower price of long distance travel
- war + conflict
- inc job opps
changes to the uk in the 1960s
- large scale housing prod = prov working class with new houses + some social housing built (often tower blocks = inc crime rates + red SOL)
- inward international mig from pakistan + india
- developt of transport of ppl e.g. aircraft + goods e.g containerisation in 1950s => acceleratiom of movmt of ppl and goods in 1960s.
- commonwealth act of 1962 = restricts the flow of commonwealth migrants to only skilled workers, enc economic mig
changes to the uk in the 1970s
- decline in secondary industry in cities e.g. liverpool + Brum => inc in unemployment + poor living conditions enc mig away from major city hubs.
- docks became unneccesary (due to improving plane transportation) = dereliction in docks e.g. london
- inward international mig from vietnam, bangladesh + chile.
changes to the uk in the 1980s
- economic recession => unemploymt + deindustrialisation (continuing from 1970s). -> discourages some international migrants (interest in job opps)
- uk govt offers tax incentives + sets SEZ to try enc FDI + TNCs to establish offices/manufacturing w/in the uk.
- basic internet developed => developt of online banking in 1984 = allowing capital + financial transactions to transfer around the world quixkly
- inward interantional mig from china, srilanka,sudan,somalia+australia.
changes to the uk in the 1990s
- growth in uk pop fue to net mig
- conflict in congo/yemen enc international mig to uk + also collapse of soviet union (as migrants wish to imporve QOL)
- first smartphone developed in 1994
- NHS begin recruiting overseas (trying to use migrants to fill their skills gap).
changes to the uk in the 2000s
- race relations amendment act aimed to red tensions + discrimination by the popo and govt
- suburbanisation accelerates = creating new towns for highly paid migrants to move into (offers rural QOL whilst maintaining job in nearby city.)
- EU freedom of movmt -> inc mig due to red limitations (mig w/in the EU)
- inc in creation of religious secondary+primary sch = cater for muslim and jewish migrants
- developt of social media (fb,twitter) = allows personal and business connections across the world
- expansion of EU => includes prev soviet states = inc no. of polish/slovakian/lithuanian migrants
changes to the uk in 2010s
- londons new rep as a multicultural city attract new migrants = shown through olympic games + election of sadiq khan + clustering of diff cultures/ethncities
- conflict in syria pushes asylum seekers to the UK
- BUT brexit causes uncertainty in migration/population patterns : inc outward migration of some brits wishing to live in spain/france , uncertainty for existing commonwealth + international mig (windrush) , closure of some TNC manufacturing plants (may wish to remain connected w the EU for logistics+ cheaper workforce + more economic certainty.)
The Rural-Urban Continuum
The population density ranges between high density, inner urban areas to low density, remote
rural areas
continuum (USCSRR)
- Urban Core
- Suburbs/urban sprawl
- Commuter settlements/expanded towns
- Suburbanised villages/market towns
- Rural villages & farming areas
- Remote rural tourism & second home areas
what suggests the changes in the rural-urban continuum
population density + the charcateristics of the built env.
urban city structure
- most cities have a similar structure ; developt occuring outwards+living conditions changing the further outwards u travel
- two models to describe this ; Burgess + Hoyt
