Slovakia, Russia, Poland, Japan, Cuba etc… The countries I listed above (among others) have very small growths/declines in population each year. It represents situation of low fertility, low mortality and high life expectancy. Stationary population identity with two variables is structured in this chapter to suit analysis required to perform on a captive cohort when there exist very large number of individuals in each age-group of a population. The median population size of the world’s top 100 cities has been growing steadily too – from eight million in 2000 to a projected 12 million in 2035.
