Age/Sex compositions have proven to be important factors in society because they are the basic characteristics and biological attributes of any demographic group. However, they do not only effect the demographics, they also impact the economic, social and political structure as well. They have ways of changing and influencing internal and external migrations, GMP, birth and death rates among seemingly unrelated things such as educational and medical services. In regards to educational services, sex-age distribution numbers can help predict decisions that are likely to be made in regards to the number of educational institutions, teacher, textbooks and so much more. It is also a key tool used ...view middle of the document...
I’m regards to New Zealand, they are much more developed and because of this we see a much more evened population graph. Almost square like to the eye, this means that there is roughly the same amount of children under 4 for the same amount of people who are in their 50’s and 60’s. As the age goes up it slims down quite a but from there. It would be concerning however if the amount of children under 4 match the nuber of 80 and 90 year olds because there is no way for the older demographic to be supported. If the same number of elderly people equals the same number of working aged people, there is no way to support our elders with benefits such as Medicare and social security because there simply would not be sufficient funds to support it. New Zealand is not quite there yet, but in countries such as Japan this is becoming a very real problem. (Gurain) Japan is almost entering what could be considered a “stage 5” in regards to the demographic transition theory where no longer can the working class support their elders because there is simply too many to support due to modern medical advances and medicine.

It isn’t shocking that Syria has a higher dependency ratio because they have way more children under the age of 14 than they do who can support them ratio wise. High birthrate means high dependency and even though Syria has a larger population does not mean they will have more of a dependency. It is all about ratios.
In regards to sex compositions over time, there...
