Explanation:

Statement 1: Globally, population aged 60 or over is growing faster than all younger age groups. In 2017, there are an estimated 962 million people aged 60 or over in the world, comprising 13 per cent of the global population. The population aged 60 or above is growing at a rate of about 3 per cent per year. Currently, Europe has the greatest percentage of population aged 60 or over (25 per cent). While declining fertility and increasing longevity are the key drivers of population ageing globally, international migration has also contributed to changing population age structures in some countries and regions. In countries that are experiencing large immigration flows, international migration can slow the ageing process, at least temporarily, since migrants tend to be in the young working ages. However, migrants who remain in the country eventually will age into the older population.

Statement 2: This concept has been covered in an earlier test and need not be explained again. Societies like USA have considerable number of immigrants augmenting their human capital especially in industries like IT.
