Year: 2014 Length: 5:01 Access: YouTube Summary: In an earlier video post from The Economist I introduced the population pyramid, which is a type of graph used by demographers to interpret population characteristics and project how those characteristics will change in the future. Using these pyramid graphs, it's possible to discern whether a given population is growing rapidly, growing slowly, or in decline, and whether the country has undergone a demographic transition. Few graphs are more useful than population pyramids, for they allow policymakers to establish tax structures, based on projections of the number of working-age people who will be able to pay taxes and the number of people who will be dependent on social services. Knowing characteristics of a population is also essential if one hopes to prevent food shortages, avoid ecological threats, and lesson the blow of chronic poverty. This video lesson prepared by Kim Preshoff is a nice primer on reading the graphs, as it compares the population distributions of a number of different countries, including Russia, Nigeria, Rwanda, Canada, Japan, China, and the United States. After watching the video and discussing the potential challenges each country faces, it's useful to ask students to find or create population pyramids for other countries and report on the challenges their chosen country faces based on its population characteristics.

I just want to say Thank You to everyone who supported me through the years. My name is Manuel Franco, New Berlin, Wisconsin. My story of how I won the Powerball lottery of $768.4M is a bit of a tale. I have been playing Powerball tickets for 6 years now since I turned 18. I bought my first ticket on my 18 birthday. I was feeling very lucky that day because I had contacted Dr. Odunga Michael to help me with the winning Powerball numbers. I really had that great great feeling that I looked at the camera wanting to wink at it. I only did a tiny part of it and trusted him. He gave me the numbers after I played a couple other tickets along with it for $10. I checked my ticket after the winnings came online and saw the numbers were correct including the Power play. I screamed for about 10 minutes because it felt like a dream. I had won $768.4M. You can check my winning testimony with the lottery officials just with my name search. Thank you Dr Odunga. Well, his email is [email protected] and you can also call or Whats-app him at +2348167159012 so you guys can contact him 8/10/2023 10:47:13 pm

My name is Hailey Garcia and I am from New Jersey. My herpes virus turned to war after 2 years of living with it. I have tried different medical procedures to cure my herpes but to no avail. Most people think herpes is only a minor skin irritation of which herpes has long term effects on health and passes through the bloodstream and can be easily contracted through sexual intercourse. I knew I had herpes from the first day I started feeling itchy in my pubic area and the pain was very unbearable. I couldn't stand it anymore. After 2 years of trying other means to get rid of it, I had to contact Doctor Odunga to help me with a permanent cure. I saw his email and whats-app number from a testimony I read online from a lady who was also helped by him in curing infertility problems, I had faith and contacted him. He assured me of his work and I ordered his herbal medicine. Within 5 days, I didn't feel any pain anymore and within 2 weeks, my skin was all cleared and smooth. I am very grateful to you sir and I write this testimony as others have done to bring those having faith to you sir. If you have herpes or other similar disease and you want it cured, kindly contact Doctor Odunga, Whats-App (wa.me/+2348167159012) OR Email [email protected]
