(i) The ‘demographic dividend’ results from an increase in the proportion of workers relative to non-workers in the population. In terms of age, the working population is roughly that between 15 and 64 years of age.
(ii) This working age group must support itself as well as those outside this age group (i.e., children and elderly people) who are unable to work and are therefore dependents.
(iii) The actual problem is in defining the dependency ratio as the ratio of the non-working age to working-age population, rather than the ratio of non-workers to workers.
(iv) India is really facing a window of opportunity generated by the demographic dividend.
