The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age–sex groups, and countries. The GBD can be used to generate summary measures such as disability-adjusted life-years (DALYs) and healthy life expectancy (HALE) that make possible comparative assessments of broad epidemiological patterns across countries and time.

Taking advantage of its growing working-age population could help accelerate South Africa’s growth to 5.4 percent a year and double per capita incomes by 2030, according to the South Africa Economic Update released by the World Bank.

Despite a continuing slowdown in the rate of population growth, it is “almost inevitable” that the number of people on the planet will rise from 7.3 billion today to 9.7 billion in 2050, according to the latest UN projections.

The Population Institute released a report on how population growth is affecting the development prospects of the world’s most fragile countries.

Extreme heat events are likely to become more frequent in the coming decades owing to climate change. Exposure to extreme heat depends not only on changing climate, but also on changes in the size and spatial distribution of the human population. Here we provide a new projection of population exposure to extreme heat for the continental United States that takes into account both of these factors.

East–Southeast Asia is currently one of the fastest urbanizing regions in the world, with countries such as China climbing from 20 to 50% urbanized in just a few decades. By 2050, these countries are projected to add 1 billion people, with 90% of that growth occurring in cities. This population shift parallels an equally astounding amount of built-up land expansion.

Coastal managers face the task of assessing and managing flood risk. This requires knowledge of the area of land, the number of people, properties and other infrastructure
potentially affected by floods. Such analyses are usually static; i.e. they only consider a snapshot of the current situation. This misses the opportunity to learn about the role
of key drivers of historical changes in flood risk, such as development and population rise in the coastal flood plain and sea-level rise.

Though there is a fair understanding of the ways in which India's population is changing as well as of the social and economic implications of these changes, little attention has so far been paid to its possible environmental impact. This article attempts to understand how the changing demographic trends have affected the environment and seeks to identify measures both to mitigate environmental damage as well as increase resource use efficiency.

The 2014 edition of the Statistical Yearbook is a reference full of up-to-date and comparable statistics and facts about the 58 regional members and associate members of ESCAP. It includes brief analyses of 32 key features of development in areas as diverse as population and demographics, child and maternal health, school enrolment and spending on education, income poverty and inequality, food security, crime, energy supply and use, disasters, economic growth, international trade, tourism and transport.
