Investopedia explains 'Dependency Ratio'
This indicator gives insight into the amount of people of non-working age compared to the number of those of working age. A high ratio means those of working age - and the overall economy - face a greater burden in supporting the aging population.
The young dependency ratio includes only under 15s, and the elderly dependency ratio focuses on those over 64. For example, if in a population of 1,000 there are 250 people under the age of 15 and 500 people between the ages of 15-64. The youth dependency ratio would be 50% (250/500).
