The presented charts describe the all-around-the-world citizens’ figures in both number and growth rate change over the period of 1950 to 2050. Overall, while the world population has a significant upward trend, the other holds a fluctuated insight throughout this timeline.
In 1950, starting at the figure of 3 billion, world population went up by a tiny number of 1 billion in the following two decades, whose total population remained unchanged until a decade later, when it surged up to 7.5 billion in the present and is projected to have 10 billion in total with no sign of going down.
In terms of growth rate, from 1950 to 1970, a huge check-like trend appears, with the beginning point at 1.5%, then dropping to 1%, and ultimately rocketing up 2% at the end of the year 1970. Next, the growth rate immediately experienced a substantial decline in the year 1980 and held firm to that trend in the next 10-year timespan, which continued this phenomenon from 2010 to 2020 with around 1% and 0.5% for the former and latter, respectively. In the future, the growth rate is predicted to decline further, with the figure reaching the percentage of 0.5% in the year 2025.
