Total population of heaven and hell today, based on assumption of 2.39% growth rate and 1.195% death rate
This insight calculates the total number of deaths, by running history in reverse. This involves having a greater death rate than birth rate, so that the population slowly dwindles.
Starting value of the population stock is given as 7,404,976,783, based on estimates for mid 2016.
When population reaches close to zero at 450 years, the estimate for total humans ever born is 14.77 billion.
