A Decade of Population Growth and Decline in U.S. Counties There are a number of factors that determine how much a region’s population changes. If an area sees a high number of migrants, along with a strong birth rate and low death rate, then its population is bound to increase over ...
It explores population decline and the difference between population emergencies and population stabilization. A thought experiment, M's Conjecture, is used to show how the greatest degree of population growth control, as well as protection against population decline, can be achieved without restricting...

In recent years Japan, Italy, and Portugal are also experiencing population decline.Footnote 4 The effect of declining population on growth and per capita income is also examined in the context of modern growth theory. Elgin and Tumen (2012) have constructed a model of fertility and growth in ...
In this perspective, the sequential stages of urban cycles are the appropriate background influencing density-dependent and path-dependent mechanisms of population growth and decline55. In other words, we assume that the individual stages of the cycle (namely, urbanisation, suburbanisation, counter-...
Episodes of population growth and decline leave characteristic signatures in the distribution of nucleotide (or restriction) site differences between pairs of individuals. These signatures appear in histograms showing the relative frequencies of pairs of individuals who differ by i sites, where i = 0,...
Africa is the only world region expected to continue to experience significant population growth. The population will be increasingly made up of larger proportions of older ages than younger, thereby shifting the dependency ratio. Reflections on the implications of an aging and shrinking population on...

In this status quo world, we keep the same economic models that assume infinite population growth and amass more debt to pay for our public spending. Our social safety nets stay the same, which, those rely on more inputs from workers than withdrawals from retirees. That's what we call a...
