ok, but if you go back further in oz interest rates, they start to rise in around 1974 and have a steady increase until this graph you have shown below which starts in the early 90's ...
our interest rates during the 80's peaked at 20% (in 82), 19% (in 85) and 18% (in 89) ... so although there may be an underlying effect of age of population, aren't there too many other factors involved to draw this conclusion from this data or does the 80's just not count because of the drama of that decade?
this chart shows the exact interest rates for each quarter of each year since 1959

what i can see is that interest rates started dropping dramatically in the 90's despite the age of the population increasing by 1.4 years at the beginning of the 80's and another 1.4 years in the mid 80's (when interest rates were at their highest) after staying the same for 20 years ... increase of 1.3 years in 1990 and 1.9 years in 1995.
So based on the theory of age affecting interest rates, why were they so high in the 80's when our population started aging? did it need a whole decade to balance out?
Serge, this is like you helping me figure out something with photoshop LMAO i'm so lost
