Population pyramids: Powerful predictors of the future

"Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps policymakers and social scientists make sense of the statistics, using three different countries' pyramids as examples."

Unit 2: Population and Migration

 

This video was about how demographers categorize data and analyze it. This video showed a few different population pyramids in order to show differences in population in different countries. It showed China as an example and pointed out the remnants of the one child policy 35 years before and how the number of men were higher due to sex selective abortions. They also talked about how the population pyramids could show what stage in the demographic transition model a country was in and how they use them to predict future patterns and changes. 

 

This relates to unit 2 because it covers topics such as population change, demographic transition models, sex composition, population policies and much more. Population pyramids are very useful due to the visualization of sex, age and number composition in a countries population. They are very important in the use of predicting the future change in population because it can tell what the population has gone through in the past and what to expect in the DTM.

This video illustrates how population pyramids have the ability to show how populations will rise and fall over time. Pyramids specifically show the population based on a specific age, and illustrates a country's amount of young people in comparison to the elderly.

How 'Metal Gear Solid' Helped Turn An Amputee Into A Maker

How 'Metal Gear Solid' Helped Turn An Amputee Into A Maker | Managing Technology and Talent for Learning & Innovation | Scoop.it

'James Young’s bionic arm will be Bluetooth-enabled, with a screen to control his electronics. It has a laser and a torch, and it can fly drones. But it has trouble picking up a grocery basket.


After losing his arm and leg in a commuter rail accident four years ago, he applied to receive a bespoke and partially 3D-printed "art arm" as part of a project called Phantom Limb, inspired by the video game Metal Gear Solid and funded by game company Konami. The arm has changed Young’s life"
