one of the reasons why the lorenz curve looks the way it does
many people live along coastlines and much fewer in the continental interiors
development
ways in which a countrys people strive to grow economically and improve quality of life. often shown by economic indicators of average wealth
population distribution
description of the way in which people are spread out across Earths surface
population density
number of people living within a specified area
lorenz curve
a diagram that shows the extent to which a distribution is unequal. dashed diagonal line – perfectly even distribution. (% people over % land – 90% of people live in 16% of the land in our case)
how much of the population obtains its income by farming the land
1/3 of the working age population, so like 2 billion people
in what continents are there low density levels in continental interiors + main reasons
inaccessibility + extremes of climate;
central areas of asia, australia, south america, saharan africa
how do human factors change the established by physical factors regions where people live
hot, arid climates will attract people once there is the necessary technology for artificial water supply
urban areas in saudi arabia have been growing bcs of petrodollars – oil wealth. the money made from them = money for the desanilisation of water + air con
state 3 human factors
economic
political
technological
state 5 physical factors
climate
soils (frozen = sparse)
physical accessibility
water supply
vegetation (dense forest/lack of vegetation = sparse)
state human and physical factors

key features of global economic development
asia and africa now have more EEs than LICs
most south america countries = EEs
some east european countries are EEs
globalisation
ways in which people and places have become connected
3 main categories of countries
HIC – income of 12600 dollars or above. country w high human development, most people have a good standard of living
EE – beginning to experience higher rates of economic growth, usually due to industrialisation, rapid factory expansion, globalisation, TNCs investment
LIC – agriculture still plays a big role. some have political instability and conflict. incomes of 1030 dollars or lower
GDP расшифровка
gross domestic product
what is GDP used for
gdp – gross domestic product
used for measuring the economic development of a country
problems w calculating GDP
its really hard to calculate bcs:
1 numerous earnings need to be accounted for
2 work in informal sector hard to quantify
define GDP
gdp – gross domestic product
the measure of the total value of output of final goods and services in a nation, used to understand economic development
what is the informal sector
unofficial forms of employment that are hard to make subject to government regulations. “cash in hand” work, often the only kind of work low skilled people can get
PPP расшифровка
purchasing power parity
define PPP
purchasing power parity
the real cost of living in a country as it considers the cost of a “basket of goods” in that country
why do regional imbalances arise in population distribution
bcs initially places w physical factors + other natural advantages (like raw material availability, access to coastline) become core regions, build on natural advantages, backwash effect => core periphery systems that strengthen over time (рисуночек)
what is backwash
the inflow of people, investment, resources from periphery to core regions
core periphery system
uneven spatial distribution of national population + wealth between regions of a country
