[PERÚ: 27 años] Oldest and YOUNGEST Populations

[PERÚ: 27 años] Oldest and YOUNGEST Populations | MAZAMORRA en morada | Scoop.it

"There are 1.2 billion people between the ages of 15 and 24 in the world today — and that means that many countries have populations younger than ever before.  Some believe that this 'youth bulge' helps fuel social unrest — particularly when combined with high levels of youth unemployment.  Youth unemployment is a 'global time bomb,' as long as today’s millennials remain 'hampered by weak economies, discrimination, and inequality of opportunity.'  The world’s 15 youngest countries are all in Africa.  Of the continent’s 200 million young people, about 75 million are unemployed.

On the flip side, an aging population presents a different set of problems: Japan and Germany are tied for the world’s oldest countries, with median ages of 46.1. Germany’s declining birth rate might mean that its population will decrease by 19 percent, shrinking to 66 million by 2060. An aging population has a huge economic impact: in Germany, it has meant a labor shortage, leaving jobs unfilled."

Unit 2

Alec Castagno's curator insight, December 17, 2014 11:05 AM

The extremely young median age seen across Africa hints at the problems found throughout the continent. This demographic factor suggests that there are other political, economic, and cultural problems that are influencing these young ages. It shows that most people do not live long lives, and even the older countries on the continent are younger than most other places. The only other place with low ages are the Middle East and Central Asia, and even their populations are several years older than the African continent.

Understanding Population Pyramids

This covers what a population pyramid is, and how to analyze one. It covers the three basic shapes and how they correspond to population growth or decline.

 

Simple introduction on how to analyze population pyramids.   Update: some these slides originally came from a different presentation, which has since been revised.  You can find the revisions at: http://houstonhs.scsk12.org/~mrobinson/Mr._Robinsons_Web_Site_at_Houston_High_School/June_Presentation.html (paste in full URL)

Unit 2 Population and Migration

This diagram is an 18 slide powerpoint explaining the uses of, how to analyze, and what a population pyramid shows. This is also in a childish language and is very easy to understand making it an easy thing to use and visualize. It shows how pyramids show fertility rates migration and workforce.

This diagram powerpoint relates to unit 2 because it shows population pyramids with population and migration data on them referencing to the units core concepts. This delves deep into the understanding of the uses of population diagrams overall and their effects on society's parts, It is overall a major part of unit 2.

[ #CONGA_WW ] Could there be 'WATER WARS' in the Future?

[ #CONGA_WW ] Could there be 'WATER WARS' in the Future? | MAZAMORRA en morada | Scoop.it

The debate on aquifers continues as new technologies designed by oil companies are able to tap historic water reserves deep in the Earth's crust.  The geopolitical significance of water rises as population growth within dry climates continue to rise.   As more countries (and people) compete for limited resources, outbreaks of armed conflict becomes more likely.   The more pertinent question might not be 'if' but 'when.'
