push factor

reasons people leave a place eg war, no jobs, traffic ,goverment, laws bad, healthcare

pull factor

reasons people move to a new place eg:better quality of life,education,safety,family.

how to calculate BR and DR

br= births in a year divided by total populationx 1000. dr=number of deaths divided by total popx 1000

how to calculate pop density (PD)

total pop divided by land area eg pop=250,000 land area =250 km so 250,000/250km=2000 so 200 people per km

how to calculate doubling time(always divide by 70)DT

DT=70/PGR EXAMPLE PGR IS 2% DT=70/2=35 DOUBLING TIME=35 YEARS.

HOW TO CALCULATE natural inrease rate(NIR)

NIR= BR-DR= For example; br =20 dr=8 so 20-8=12 NIR = 12 Per 1000 people.

how to calculate PGR

pop end-pop start divided by popstart x 100

what do u mean by variables

variables are like this BR=BIRTH RATE DR=DETH RATE OR PGR= POP GROWTH RATE

whats the diff between PGR and NIR

NIR means the natural increase rate using the formula of the BR and DR while (Pop growth rate)PGR means the total pop growth and is used to form the pop end and pop start to calculate.

talk to me about pop pyramids

base=children(0-14)

middle=working adults

top=elderly age(65+)

anomaly is somthing unusual(war,disease)

Pop pyramid info

LIC=wide base,shrikied middle,narrow top(many kids),Youthful pop

MIC=more balanced,stable pop,short top thats getting taller,Stable pop

HIC=tall top,narrow base,inverted middle,Shrinking Population.

What does ESPN stand for and lrelate them to push and pull facotrs

E-Economic=jobs,tax

S-Social=traffic,family,education

P-Political=war,gov laws

N-Natural=natural disasters,whether.

List Me atleast 5 demographic challenges

Youtful Population=more youth

Aging population=More elderly

Overcrowding=Too many people in one areq

Urban sprawl=cities spread uncontrollably

Brain Drain=Skilled people leave their own country for a better life

Food insecurity=people lack enough food

Slum Growth=More poor,crowded nehborhoods appear because many people move there

Root Caues

Youtful Pop=High BR

Aging Pop=Low BR

Overcrowding= High PGR

Brain Drainage= Low job oppurtunities in country

Urban Sprawl=High PGR AND HIGH IMMIGRATION

Slum Growth= High housing prices,Low availibility of housing

Food Insecurity=High PD + High prices of healthy food.

Short term solution

Pros:Act quickly

Cons:Only temporary

Long term Solution

Pros:Adresses the root of a demographic challenge,IMPROVES QUALITY OF LIFE,effective in the long term

Cons:Need lots of money and time
