By about 2050, the <u>elderly</u> populations in <u>low income countries</u> are expected to boom.
It is expected that in the next thirty years, the world's population would increase by 2 billion persons, that is, become 9.7 billion instead of the present 7.7 billion.
The older population is increasing because of the increased life expectancy as well as the falling fertility levels. Several countries are experiencing a reduction in population size and their number keeps on increasing.
This change eventually has a major impact on the achievement of the Sustainable Development Goals or the SDGs, which are the globally agreed targets to achieve economic stability over years.
