Key Points
Population Distribution defined.
Population distribution refers to the spatial arrangement of people across the planet.
Density of Population formula.
Density = Population/Area. It shows how many individuals live in a unit area.
World's population in 21st century.
Over 6 billion people were recorded. Distribution is uneven globally.
Asia's populous countries.
Six of the ten most populous countries are in Asia, comprising 60% of global population.
Importance of fresh water.
Availability of water attracts populations; river valleys are densely populated.
Trade-offs in landforms.
Flat plains support agriculture; mountains deter settlement due to harsh conditions.
Climate influences.
Moderate climates attract people; extreme climates result in lower populations.
Fertile soils boost populations.
Regions with fertile soils support intensive agriculture, increasing population density.
Economic opportunities draw people.
Mineral-rich areas promote industrial migration, exemplified by Zambia's copper belt.
Urbanization trend.
Cities provide jobs and amenities, leading to rural-to-urban migration.
Demographic Transition Theory stages.
Population shifts from high birth/death rates to low rates as societies progress.
Components of population change.
Births, deaths, and migration affect population dynamics and growth.
Natural Growth equation.
Natural Growth = Births - Deaths indicates population increment without migration.
Crude Birth Rate (CBR) explained.
CBR = (Live Births/Population) × 1000; indicates birth frequency in a population.
Crude Death Rate (CDR) explained.
CDR = (Deaths/Population) × 1000; measures mortality in a population.
Migration factors.
Push factors (e.g., conflicts) drive people away; pull factors (e.g., jobs) attract them.
Positive growth defined.
Positive growth occurs when births exceed deaths or when net migration is positive.
Negative growth explained.
Negative growth happens when deaths exceed births or through significant emigration.
Malthusian theory overview.
Thomas Malthus posited that population increases faster than food supply, risking famine.
Population control measures.
Family planning, education, and contraceptive availability are crucial for managing growth.
Global population growth trends.
Human population surged over tenfold in 500 years; rapid growth is evident in the 20th century.
