Dependency ratio is the proportion of the population that is outside the labour force and thus dependent on the economic activity of those working. The dependency ratio is an age-population ratio of those typically not in the labor force and those typically in the labor force. Total dependency ratio (0-14 and 65+ per 15-64) of India fell gradually from 79.1 ratio in 1970 to 52.2 ratio in 2015.
Dependency ratio is typically calculated as the proportion of the population between the ages of 0 to 16 plus those over 65 to those between the ages of 16-65. The dependency ratio is a statistic that has been used extensively by demographers, economists and policy analysts to portray the impact of population aging.
Dependency ratio has also been widely used as evidence for the argument that an aged population will cause both economic crisis and intergenerational warfare for developed nations. Few critiques of dependency ratio's value as a reliable indicator of future trends, however, have been conducted. In this analysis, the appropriateness of such projections about the future of the economy in developed nations, and the burden of caring for an aging population, are considered.
A deconstruction of the components of the dependency ratio suggests that its assumptions about the relationship between people, age and productive labor, raises important doubts about the likelihood that forecasts of crisis will be correct. - Deconstructing Aged Dependency: An Assessment of the Dependency Ratio as an Indicator of Population Aging - Donoghue, Chris - Abstract.
Some Thoughts on Reformulating the Dependency
Crown, William H. - Gerontologist, v25 n2 p166-71 Apr 1985.
Abstract: Develops and applies methodology for systematically examining dependency of alternative demographic groups within the context of total dependency ratio using Bureau of Census and Bureau of Labor Statistics data. Although total dependency ratio increases as population ages, those under 16 will continue as the largest dependent group in future years.

Dependency Ratio, Foreign Capital Inflows and the Rate of Savings in Pakistan
Ashfaque, Lubna Hasan, Afia Malik - The Pakistan Development Review, Vol. 4, No. 31, pp. 843-856, 1992.
Abstract: Domestic resource mobilization is one of the key determinants of sustained economic growth. The savings rate in Pakistan is sensitive to per capita income, dependency ratio, real interest rate and foreign capital inflows. Dependency ratio and foreign capital inflows exert a depressing effect on savings while income and real interest rate have a positive effect.
