In a world in which much change is unpredictable and immediate, global ageing - the unprecedented increase in global population over the age of 60 - is a highly foreseeable long-term trend. It is also, of all global issues, one of the most amenable to risk management in terms of identification, measurement and mitigation of possible consequences. Population ageing and its feminization - evidence and determinants In the year 2000, the number of persons aged 60 years and over was greater than the number of children below 5 years; and by 2050, Implications of population ageing for economic growth David E. Bloom, David Canning, and Günther Fink* Abstract The share of the population aged 60 and over is projected to increase in nearly every country in the world during the period 2005-50. Population ageing will tend to lower both labour-force participation and savings 2. Population Aging . 2.1. Trends and Projections . This section documents some salient facts and trends in population ageing. Overall, major changes have occurred in the world's age and population structure over the last half-century, with the increase in population shares at advanced ages being a prominent feature. Figure 1 tion growth (the result of its population momentum) and rapid population aging. Between 2005 and 2030 China is expected to grow by more than 100 million people; at the same time, the proportion of the population above age 60 will more than double from 11 percent to around 25 percent.

These messages are based on the report World Population Ageing 2019, which provides an overview of global trends and dynamics of population ageing and discusses conventional, prospective and economic measures of population ageing.

The proportion of individuals aged 80 or over is projected to rise from 1 percent to 4 percent of the global population between today and 2050.1 Meanwhile, the growth in the working age population (age 20-64) will slow drastically. While the working age population increased 56% between 1990 and 2015, this age group will grow just 22% between 2015 and 2040 (Figure 2). During this same 2015-2040 period, the age 65+ population will increase globally by 114%. In fact, the percent of global Population ageing is a common social and economic agenda, with 70% of all older people living in G20 countries. Ageing is a cross cutting theme in G20 discussions for 2019. There was a specific focus on ageing within the health working group (HWG) which met in Tokyo on 28 February and 1 March 2019 to initiate discussions and share national are smaller, the population as a whole is ageing. All countries experience this process sooner or later. The most frequently used indicators to demonstrate this are the percentage of people above a certain age (60 or 65), and the median age of the population. How is society affected by population ageing? The number and proportion The Interna
