World Population Ageing 2019 World Population Ageing 2019 Highlights ST/ESA/SER.A/430 Department of Economic and Social Affairs Population Division World Population Ageing 2019 Highlights United Nations New York, 2019 The Department of Economic and Social Affairs of the United Nations Secretariat is a vital interface between global policies in the economic, social and environmental spheres and national action. The Department works in three main interlinked areas: (i) it compiles, generates and analyses a wide range of economic, social and environmental data and information on which States Members of the United Nations draw to review common problems and take stock of policy options; (ii) it facilitates the negotiations of Member States in many intergovernmental bodies on joint courses of action to address ongoing or emerging global challenges; and (iii) it advises interested Governments on the ways and means of translating policy frameworks developed in United Nations conferences and summits into programmes at the country level and, through technical assistance, helps build national capacities. The Population Division of the Department of Economic and Social Affairs provides the international community with timely and accessible population data and analysis of population trends and development outcomes for all countries and areas of the world. To this end, the Division undertakes regular studies of population size and characteristics and of all three components of population change (fertility, mortality and migration). Founded in 1946, the Population Division provides substantive support on population and development issues to the United Nations General Assembly, the Economic and Social Council and the Commission on Population and Development. It also leads or participates in various interagency coordination mechanisms of the United Nations system. The work of the Division also contributes to strengthening the capacity of Member States to monitor population trends and to address current and emerging population issues.

All societies in the world are in the midst of this longevity revolution—some are at its early stages and some are more advanced. But all will pass through this extraordinary transition, in which the chance of surviving to age 65 rises from less than 50 per cent—as was the case in Sweden in the 1890s—to more than 90 per cent at present in countries with the highest life expectancy. What is more, the proportion of adult life spent beyond age 65 increased from less than a fifth in the 1960s to a quarter or more in most developed countries today. These changes for individuals are mirrored in societal changes: older persons are a growing demographic group in society. Older people account for more than one fifth of the population in 17 countries today, and the United Nations Department of Economic and Social Affairs Population Division’s projections to the end of the century indicate that this will be the case in 2100 for 155 countries, covering a majority (61 per cent) of the world’s population. Traditionally, the United Nations and most researchers have used measures and indicators of population ageing that are mostly or entirely based on people’s chronological age, defining older persons as those aged 60 or 65 years or over. This provides a simple, clear and easily replicable way to measure and track various indicators of population ageing. However, there has been increasing recognition that the mortality risks, health status, type and level of activity, productivity and other socioeconomic characteristics of older persons have changed significantly in many parts of the world over the last century, and, in particular, in the last few decades. This has led to the development of alternative concepts and measures to offer a more nuanced perspective of what population ageing means in different contexts. New measures and concepts of population ageing have significant implications for assessing the living conditions and living arrangements of older persons, their productive and other contributions to society and their needs for social protection and health care. These new approaches to understanding and measuring ageing also carry important implications for the review of internationally agreed development goals, including those contained in the Programme of Action of the International Conference on Population and Development (ICPD), the Madrid International Plan of Action on Ageing (MIPAA) and, most recently, the 2030 Agenda for Sustainable Development.

Ralph: Longevity Extension Longevity Extension from a Socioeconomic Perspective: Plausibility, Misconceptions, and Potential Outcomes Eric Ralph Introduction In the last several decades, a significant amount of progress has been made in pursuits to better understand the process of aging and subsequently gain some level of control over it. Current theories of aging are admittedly lacking, but this has not prevented biogerontologists from drastically increasing the longevity of yeast, drosophilae, worms, and mice (Vaiserman, Moskalev, & Pasyukova 2015; Tosato, Zamboni et al. 2007; Riera & Dillin 2015). Wide-ranging successes with gene therapy and increased comprehension of the genetic components of aging have also recently culminated in numerous successes in extending the longevity of animals and the first human trial of a gene therapy to extend life through telomerase manipulation is already underway, albeit on a small scale (Mendell et al.

  • Strategy and Action Plan for Healthy Ageing in Europe (2012–2020)
    Regional Committee for Europe Sixty-second session Malta, 10–13 September 2012 Strategy and action plan for healthy ageing in Europe, 2012–2020 Regional Committee for Europe EUR/RC62/10 Rev.1 Sixty-second session + EUR/RC62/Conf.Doc./4 Malta, 10–13 September 2012 10 September 2012 122346 Provisional agenda item 5(c) ORIGINAL: ENGLISH Strategy and action plan for healthy ageing in Europe, 2012–2020 The WHO European Region has a rapidly ageing population. The median age is already the highest in the world, and the proportion of people aged 65 and above is forecast to almost double between 2010 and 2050. The average age of the population and the proportion of people above retirement age are also projected to increase fast, even in countries with life expectancies that are well below the European average. Allowing more people to lead active and healthy lives in later age requires investing in a broad range of policies for healthy ageing, from prevention and control of noncommunicable diseases (NCDs) over the life-course to strengthening health systems, in order to increase older people’s access to affordable, high-quality health and social services. Investing in healthy ageing has become key for the sustainability of health and social policies in Europe. A closing window of opportunity of relative growth of the labour force along with unfavourable economic prospects in many countries in Europe have made the need to step up the implementation of policies for active ageing particularly urgent. This document contains a draft strategy and action plan for healthy ageing in Europe.

  • Demography Roman Spain
    CARRERAS MONFORT C. A new perspective for the demographic study of Roman Spain. Revista de Historia da Arte e Arqueologia n.2, 1995-1996; pp. 59-82. A NEW PERSPECTIVE FOR THE DEMOGRAPHIC STUDY OF ROMAN SPAIN César Carreras Monfort* * Universitat Oberta de Catalunya e-mail: [email protected] In the last years, there has been an increase in the number of demographic studies of ancient societies, with the main aim to recognize the internal organization of the populations and, to some extent, how the resources of a territory determined patterns of distribution [Gallo, 1984; Parkin, 1992]. Actually, within the limits of the Roman society, these studies allowed us to revise again basic concepts such as the relationship between the urban and rural world [López Paz, 1994], or even, to discuss about the degree of urbanism that supposedly it is accepted for the Graeco-Roman world. The demographic analyses on the Roman period were recently favoured by a better knowledge now, of the urban perimeters of ancient Roman cities, and the patterns of rural distribution; thanks to the contribution of either the urban archaeology and the rural field-surveys [Barker, 1991] and cadastres studies [Chouquer and Favory, 1991]. Furthermore, the important contribution of papyrology also stands out, since they supply information on demography, which despite being basically about Roman Egypt, it can be extrapolated to other provinces [Hombert and Preaux, 1952; Bagnall and Frier, 1994]. These new documental evidences allow us to carry out a new estimate, from another viewpoint, of the population in a very particular province such as Roman Spain, and also they become a headway in the detailed study of population patterns.

  • Equatorial Guinea, a Multidrug-Resistant Tuberculosis Hotspot in Central Africa
    ERJ Express. Published on December 23, 2016 as doi: 10.1183/13993003.00952-2016 AGORA | RESEARCH LETTER Equatorial Guinea, a multidrug-resistant tuberculosis hotspot in Central Africa To the Editor: The national tuberculosis programme (NTP) of Cameroon has recently reported that an alarming number of tuberculosis (TB) patients are border-crossing from neighboring Equatorial Guinea to seek multi-drug- resistant tuberculosis (MDR-TB) treatment [1, 2]. The World Health Organization (WHO) African Region is reported to bear a low MDR-TB proportion of new tuberculosis cases (2.1%) compared with other WHO regions [3]. Nonetheless, there are big differences between African countries, and data on MDR-TB burden are still lacking from almost half of them. Some could hide true MDR-TB hotspots, brought about by weak diagnostic and control capacities and fueled by health and social factors of vulnerability [4, 5]. Equatorial Guinea is a small country in Central Africa. It is made up of an insular region (capital Malabo) and an inland region (capital Bata). Its population (1.2 million) has experienced deep lying sociodemographic changes since it became a major oil producer in the early 1990s [6]. Despite the country’s booming economy (its gross domestic product ranks 43rd in the world) social and health [7] indicators remain very low, ranking 138th in the Human Development Index. HIV prevalence is rising, with the last national estimation being 6.2% in 2011 [8, 9]. Tuberculosis incidence rates are increasing (172 cases per 100000 population in 2015) and national tuberculosis treatment success rate is declining (62% in 2014) [10].

  • Cycling Accident Fact Sheet
    Traffic Safety Basic Facts 2013 - Main Figures Traffic Safety Basic Facts 2018 Cyclists Traffic Safety Basic Facts 2018 – Cyclists General In 2016, about 25.600 people were killed in road accidents throughout the EU, a reduction of 40% from the 2007 total of 43.150. This fact sheet explores the known characteristics of cyclist fatalities. Cyclists, while relatively small in proportion with respect to motorized vehicles, have a high level of vulnerability, creating a significant need to better understand the characteristics specific to this user group. A good insight into the problem provides an opportunity to improve the safety of this cheap, convenient and environmentally safe mode of transport. Fatality refers to any road user who was killed outright or who died In 2016, about 2.000 cyclists within 30 days as a result of the accident. This fact sheet addresses were killed in road accidents cyclists fatalities hereinafter referred to as fatalities. The term “bicycles” in the EU countries, 8% of all refers only to push bikes. The most recent year or period for which data road fatalities. are available has been analysed. Bicycle fatalities make up 8% of the total number of road accident fatalities in 2016 in the EU countries. In these countries, 2.015 people riding bicycles were killed in road accidents in 2016 (excluding Lithuania and Slovakia). Figure 1: Number of cyclist fatalities and all road fatalities, EU, 2007-2016 Source: CARE database, data available in May 2018 Figure 1 shows both the number of cyclist fatalities and the number of all road fatalities in the EU between 2007 and 2016.
