Explanation
Since the annual growth should be assumed as a constant to find a linear progression model which consists of the beginning value (y₀), the end value (yₙ) and the time difference (n) and can be calculated: additional subscribers per year (b) = (yₙ - y₀) / n.Sub-Saharan Africa gains more than 550 million new subscribers within 4 years (between 2016 and 2020) so it could be that also the APAC region will exceed the 550 million new subscribers within 10 years (between 2020 and 2030), as this region also has a considerable number of inhabitants and showed a substantial growth between 2012 and 2020. In contrast, all the other regions are having too low subscription increases to consider more than 550 million new subscribers by 2030 plausible.
