It’s interesting to look at some long-term world trends at the end of 2013. The graphs appear more normalized, for instance with the population growth rate above. Countries like Nigeria (see population chart below) are unfortunate exceptions. How will the world really look like in 2050? Trends are extrapolations from current and past data, enhanced with some mathematical modeling. Forecasts cannot account for unforeseeable events, but they are probably pretty accurate. We’ll see in 5 or 10 years from now, looking back, how good these numbers were. World Population Growth Rate Population in the world is currently growing at a rate of around 1.14% per year. The average population change is currently estimated at around 80 million per year. Annual growth rate reached its peak in the late 1960s, when it was at 2% and above. The rate […]
