Implications of Urbanisation on world population and growth in urban and rural areas Flashcards
what was the world population growth in 1950
The world population was around 2.6 billion in 1950 and reached 7 billion in October 2011.
what is the world population expected to reach
9.7 billion by 2050 and potentially peak at nearly 11 billion by 2100.
what has population growth been driven by
Population growth has been driven by factors such as
increased survival to reproductive age,
improved healthcare,
technological advancements,
rising living standards,
urbanization, and
migration.
when and what % did the population rate peak at
around 1968 at 2.1%, but it has been declining since then, with the current rate at approximately 1.05%.
do growth rates vary across countrys
yes, Growth rates vary across countries and regions, with some parts of Sub-Saharan Africa having rates higher than 3%.
what are developing regions expected to experience
Developing regions are projected to experience the greatest population growth between 2015 and 2100.
what will rapid population growth present challenges
for sustainable development, especially in the least developed countries.
what is happening with the share of the population residing in cities worldwide
it is increasing
how many people of the population live in cities in Northern America
In Northern America, more than half of the population lived in cities with 500,000 inhabitants or more in 2018.
explain Africa and Asia population growth rates
Africa and Asia have a higher rural population, but the number of cities with 500,000 inhabitants or more is expected to grow in both regions.
what is urbanisation
urbanisation refers to the proportion of people living in urban areas compared to rural areas
what are megacities
defined as cities with a population of over 10 million, are rapidly growing, with 43 projected by 2030, mostly in developing regions.
how many megacities are their currently
Currently, there are 40 megacities, with over half located in Asia and the Pacific. By 2030, eight new cities are expected to become megacities.
where is expected to be the most populated city by 2100
Lagos, Nigeria, with a population of 88 million.
what does urbanisation lead to
expansion of city borders and the growth of megacities, such as New York City and Tokyo.
what can megacities vary
vary in their ability to provide basic necessities, witha difference in level of treatmen between developed and developing nations.
what does the level of development of a country affect
its population growth rates, with declining fertility rates as countries develop.
what is urban living associated with
Urban living is associated with
higher education levels,
better health,
longer life expectancy,
access to social services, and
cultural opportunities.
why are fertility rates lower in urban areas even with child survival rates higher
due to education and delayed childbirth for women in the workforce
what happens as urbanisation increases
the population in rural areas tends to decrease or slow down due to migration to urban areas
why are younger demographics attracted to urban areas
for better employment, education and social/cultural opportunities
what does this increase in females moving to urban areas cause
this leads to negative natural growth in rural areas, resulting in an aging population and lower economic diversity
what do rural areas often experience
population loss, leading to challenges and a ‘circle of decline’
where is population decline seen
western australia, particularly in the wheatbelt region, have seen significant population declines, resulting in economic decline.
