Population Clock

StarterHow fast is the world's population increasing?What are the components of the increase? What will the worlds population be at the end of this lesson?

Key terms:

Population: the people who inhabit a territory or statePopulation growth rate: is the rate at which the number of individuals in a population increases. Population explosion: the expansion of a biological population, especially the growth in human population resulting from a decrease in infant mortality and an increase in longevity. Growth RateThe world's current growth rate is about 1.3%, representing a doubling time of 54 years. We can expect 12 billion people by 2054!

Global Population growth: Model AnswersUsing historic and future global population growth describe the overall pattern of global population growth.The overall pattern shows an increase in global population between 1750 and projected figures for 2150. Population was under 1 billion in 1750 and is projected to rise to over 10 million by 2150. Global population has increased rapidly from the 1950s onwards, particularly in LEDCs however, the growth has slowed in MEDCs since 2000 and is projected to slow further in the future.Using historic and future global population growth describe the contribution made by LEDCs to global population growth.LEDCs are responsible for contributing the most people to the worlds population. Rapid rise in population in these countries since the 1950s has led to a population explosion in this part of the world. By 2150 it is projected that approximately 90% of the worlds population will be inhabitants of LEDCs.Using historic and future global population growth describe the contribution made by MEDCs to global population growth.MEDCs show steady population growth between 1750 and 2150. The period of sharpest increase was between 1900-2000. Since the year 2000 population has leveled out and is set to slowly decline from 2050 onwards.The worlds population is not growing in a uniform way. Some regions of the world are contributing more to global population growth. How has the global distribution of population changed since 1800?Some continents have contributed a lot more to global growth than others. For example, Asia is currently home to more than half the worlds population (approximately 60.8%), this has changed very little since 1800 and is set to continue until 2050. Oceania has contributed the least to global population growth with just 0.2% in 1800 and a projected 0.5% in 2050. Patterns of growth have also changed within continents since 1800, for example 20.8% of the worlds population resided in Europe in 1800. While population in Europe rose steadily to 24.7% by 1900 since then it has declined rapidly and this is set to continue until 2050 when just 7% of the worlds population will inhabit this area. Africa, on the other hand, has shown slow growth in population between 1800-2000 but is set to double by 2050.

Population clock - reviewWhat are the implications of current and future growth rates?

While Americans grumble about gasoline prices, food riots have seared Bangladesh, Egypt and African countries.Countries like China, India and Indonesia have restricted exports and rice is shipped under armed guard.Right now, there is enough grain grown on earth to feed 10 billion vegetarians.Many agronomists think the world could easily support 20 billion to 30 billion people.
