HISTORY & MATHEMATICS Political Demography & Global Ageing

<div>Among different important issues, which are discussed in Political Demography the</div><div>issue of global ageing becomes more and more pressing every year. It is sufficient to take</div><div>into account the point that within two forthcoming decades a rapid global increase in the</div><div>number of retirement-age persons will lead to its doubling within this fairly small historical</div><div>period. The concerns about population ageing apply to both developed and many developing</div><div>countries and it has turned into a global issue. In forthcoming decades the population</div><div>ageing is likely to become one of the most important processes determining the future society</div><div>characteristics and the direction of technological development.</div><div>The present volume of the Yearbook (which is the fifth in the series) is subtitled ‘Political</div><div>Demography & Global Ageing’. It brings together a number of interesting articles</div><div>by scholars from Europe, Asia, and America. They examine global ageing from a variety</div><div>of perspectives.</div><div>This issue of the Yearbook consists of two main sections: (I) Aspects of Political</div><div>Demography; (II) Facing Population Ageing.</div><div>We hope that this issue will be interesting and useful both for historians and mathematicians,</div><div>as well as for all those dealing with various social and natural sciences.
