The economic impact of an ageing population affects us all. The author deconstructs our preconceptions and offers an original and surprising analysis.

Thibault Prébay, a renowned asset management professional, links demographic trends to markets, growth and investment.

A lively text, illustrated with examples and supported by a narrative tone that makes for smooth reading.

In this engaging and well-researched essay, Thibault Prébay explores a silent revolution: the aging of the world's population and its economic, social, and ecological impacts.

An initial observation: the decline in birth rates is irreversible. It is better to adapt than to dream of an unlikely rebound. Based on solid data, the author establishes links that are rarely highlighted between demographics and inflation, employment, debt, pensions, investment, and energy transition.

With clear chapters enriched with concrete examples, the book deciphers the causes of this decline in births, outlines the consequences it will have on our societies and their economic balances, which will change radically, and the opportunities it opens up if we stop denying it.

A book that is at once societal, economic, and political, accessible to the curious general public as well as decision-makers. It aims to fuel public debate and help decision-makers and citizens alike to think differently about the future in an era of declining birth rates.
