Trends of Dependency Ratio of Taiwan (2008-2011) Although the birth rate is declining and people tend to live longer in Taiwan , the dependency ratio in 2011 is less than that in 2008, that’s a quite interesting result. But we know that the dependency ratio is just a rough way to indicate the pressures on people aged 15 - 64 , there are other factors putting pressures on them. Here I just compare the dependency ratio in 2011 with that in 2008 to see the trends of it.

Aging Index = population (over 65) / population (under 15) Young Dependency Ratio = population (under 15) / population (15 - 64) Old Dependency Ratio = population (over65) / population (15 - 64) Dependency Ratio = population (over65) + population (under 15) / population (15 - 64)

Trends of Dependency Ratio of Taiwan (2008-2011)

Changes in Young Dependency Ratio of Taiwan ( 2008-2011 ) Due to the decline in birth rate, the changes in Young Dependency Ratio had all been reduced . However , this does not mean that the pressures of parents in Taiwan had also been reduced , actually , bad economical condition is one of the reason that made the birth rate decline.

Changes in Old Dependency Ratio of Taiwan ( 2008-2011 ) Generally speaking, towns in western Taiwan have greater positive changes against towns in eastern Taiwan. LiouChou in PingTung has the largest change ( + 1.24 % ) , which means either the nubmer of the elderly there has been increasing or the number of people aged 15 - 64 has been declining.
