60% of the world is from asia 

Majority of the population is in the age range of 30-49

Majority live in urban area  56%

Key point 1: Where is the world's population distributed. 

Demographics is the study of population. It influences policies

Population Concentrations 

• The four largest population clusters, 

  • East Asia (Vast majority in china)  

  • South Asia 

  • South East Asia, indonesia java and sumatra  

  • Western Europe, near cities, not a lot of farmers. 

  • Other population clusters are the americas, africa 

Sparsely populated are the deserts and forest. 

Ecumene: Hospitable and average regions, good to live. 

Nonecumene: Difficult to live in an area. 

1800, one billion people

1950, 53 years 

90% of the population lives in the north of the equator. 

Arithmetic density: the total number of people divided by the total land area

Physiological density: the number of people per unit area of arable land.

Agricultural density: ratio of number of farmers to arable land. 

MDC countries' agricultural density is low. 

LDC countries’ agricultural density is high. 

Carrying capacity: how much can that land sustain. 

Crude birth rate - The crude birth rate is the annual number of live births per 1,000 population. The crude birth rate is generally computed as a ratio.

Natural Increase rate - death rate - birth rate. 

a 2.2 birth rate is good for a stable population. 

Demographic transition

• A process of change in a country’s population. 

• 4 stages 

• Gives information about migration and economics 

Stage 1: Low growth 

• Early stages of humanity 

• Even with the agricultural revolution population stayed the same because food production was unpredictable 

• High CBR and CDR 

Stage 2: High Growth 

• CDR falls rapidly and CBR remains high thus NIR is high 

• Result of industrial revolution for MDCs 

• Does Not diffuse to LDCs until around 1950 because of Medical revolution 

Stage 3: Moderate Growth 

• CBR drops sharply: CDR falls at slower rate 

• Europe and NA move to this stage 1st half of the 20th century

• Asia and LA just moving to this stage 

• Africa not there yet

Stage 4: Low growth 

• Very low CBR and decline to the point where it equals the CDR and the NIR approaches 0 

• Known as zero population growth 

• Most european countries US 

• Declining birth rates

• Countries depend on guest workers. 

• Lifestyles changes 

• Total population growth is higher than stage 1 

Is there a declining Birth rate? 

Yes since the birth rate is declining. 

demographic/hidden momentum 

• Continued population growth long after replacement level fertility rates have been reached. 

J curve 

• Boom or bust populations

• Grow slowly at first then shoot up

• Once they exceed resources 

S curve 

More stable population growth 

Slow quick growth

Family planning around the world

• Measures 

Unit 2 notes - feb 5 

Thomas malthus 

• Essay on the principle of population growth

• Population would grow exponentially but food resources would not keep growing. 

• Critics of malthus say that shortages will be overcome. 

• Neo-malthusians, say people fight for resources. 

Over production and under production. 

]

Water resources and non renewable sources of energy are growing slowly but the consumption is growing fast. 

Epidemiological transition 

• Omran: 1971

• 5 stages 

  • Stage 1: Pestilence and famine - contagious diseases,- plague, black death, famine

  • Stage 2: Receding Pandemics -  treatment of natural diseases. 

  • Stage 3: degenerative and human created diseases, - obesity, diabetes, cancer thru smoking

  • Stage 4: Delayed degenerative diseases - treatment to those diseases. 

  • Stage 5: Reemergence of infectious and parasitic diseases- Covid, ebola, evian flu- not so prepared.
