Dependency Ratio = (% under 15) + (% over 65) x 100
% between 15 and 64
The dependency ratio tells you how many economically inactive people (0-15 and 65+) are dependent upon the economically active population (16 to 64).
The equation above calculates a figure which shows the number of economically inactive people that are reliant on 100 economically active people.
So a result such as 81.8 would mean that for every 100 economically active people there are 81.8 economically inactive people.
The Ageing Ratio is the
proportion of 65+ to
the whole popn.
