After analyzing many past events, I think one of the most important global demographic issues, I think one of the most notable event is the global uneven population growth. It means the population growth is not consistent around the world. In week 13, the documentary named “demographic winter” shows how a decrease in the population becomes a growing concern for some of the countries in the world. The countries under the EU, Japan, and North American Countries has been affected most by the population decrease. But, on the other hand, the countries in the Asia, Africa and Latin America are facing a substantial increase in the population growth.
