1. General trend and population changes
Within Japan there has been a steady increase of the population in both sexes. This increase has been steady until 2015 where it dipped back down to 126’573 thousand people, which is just lower than what it was in 2005 at 126’979 thousand people (United Nations, 2015). Japan has one of the few countries with a decreasing population. This is a problem for the country and needs to be solved quickly.
1.2. China, Hong Kong SAR
The population of the Hong Kong SAR section of China is slowly increasing similar to the rest of the world. The one difference is that it is doing so at a lower rate. Hong Kong starts with a very low population of 1’974 thousand …show more content…
Japan’s population is not going to be able to support itself with its current dwindling numbers, especially at the current rate the population is decreasing. On the other hand China, wants this decrease. China has the largest population in the world and is having troubles sustaining such large numbers. They don’t have the resources to maintain such a healthy large population, in such they have made policies, specifically the one-child policy, to insure that the population does stop increasing (Casper, …show more content…
It Within Eastern Asia, there are many countries on many different levels of the spectrum of the theory. However, because of China’s large population it blocks out the other countries influence when observing the entire Eastern Asia region (Casper, 2016).
Currently in the United States there is a family and household transition occurring. The family and household of many Americans is changing where there are becoming more urban and have lower fertility. In terms of Demographic Transition Theory the United States is Stage three. The US is starting to see a decrease in fertility to match that of mortality but there is still some room for it to decrease (Casper, 2016).
4. Doubling time Uniquely, Japan does not have a doubling time. Due to the country having a RNI that is negative one cannot compute the doubling time. It can however compute the halving time. To estimate the halving time one uses the same calculation as one would use to find the doubling time, the Rule of 70. This rule helps anyone find the time it would take to double or in this case halve the population, although we do manipulate it a little to get 69.3, which is the natural log of 2 times 100 (Casper, 2016). How the rule works is one divides 70 by the RNI of the country. In the case of Japan it is 70 divided by -1.7, which approximately equals 40.8. This means
