In 2011, the European Commission put forward a roadmap for a competitive low-carbon Europe by 2050. The roadmap presented possible action up to 2050 which could enable the EU to deliver greenhouse gas reductions in line with the 80 to 95% target agreed internationally in the context of necessary reductions by developed countries as a group. The roadmap outlined milestones towards the target, policy challenges, investment needs and opportunities in different sectors.
The group of 47 least developed countries (LDCs) continues to have a relatively high level of fertility, which stood at 4.3 births per woman in 2010-2015. As a result, the population of these countries has been growing rapidly, at around 2.4 % per year. Although this rate of increase is expected to slow significantly over the coming decades, the combined population of the LDCs, roughly one billion in 2017, is projected to increase by 33 % between 2017 and 2030, and to reach 1.9 billion persons in 2050.
Similarly, Africa continues to experience high rates of population growth. Between 2017 and 2050, the populations of 26 African countries are projected to expand to at least double their current size.
Compared to 2017, the number of persons aged 60 or above is expected to more than double by 2050 and to more than triple by 2100, rising from 962 million globally in 2017 to 2.1 billion in 2050 and 3.1 billion in 2100.
In Europe, 25% of the population is already aged 60 years or over. That proportion is projected to reach 35% in 2050 and to remain around that level in the second half of the century. Populations in other regions are also projected to age significantly over the next several decades and continuing through 2100. Africa, for example, which has the youngest age distribution of any region, is projected to experience a rapid ageing of its population. Although the African population will remain relatively young for several more decades, the percentage of its population aged 60 or over is expected to rise from 5% in 2017 to around 9% in 2050, and then to nearly 20% by the end of the century.
Globally, the number of persons aged 80 or over is projected to triple by 2050, from 137 million in 2017 to 425 million in 2050. By 2100 it is expected to increase to 909 million, nearly seven times its value in 2017.
The gap in life expectancy at birth between the least developed countries and other developing countries narrowed from 11 years in 2000-2005 to 8 years in 2010-2015. Although differences in life expectancy across regions and income groups are projected to persist in future years, such differences are expected to diminish significantly by 2045-2050.
The region's vision for 2050 is to provide exceptional quality of life, opportunity for all, connected communities, a spectacular natural environment, and an innovative, thriving economy.
At PSRC, VISION 2050 and the MPPs inform updates to the Regional Transportation Plan and Regional Economic Strategy. The MPPs provide policy direction for the implementing the Regional Growth Strategy. VISION 2050 actions outline responsibilities and tasks for PSRC, local governments, and others to implement the plan. Learn more about regional planning.
The region is experiencing a housing affordability crisis. VISION 2050 identifies coordinated strategies, policies, and actions to expand housing options and create greater affordability. Learn more about the Regional Housing Strategy.
VISION 2050 plans for economic growth and opportunity that creates widespread prosperity and living-wage jobs throughout the region. The plan encourages more dispersed job growth, especially in Snohomish, Pierce, and Kitsap counties, to provide greater access to employment and better balance of jobs and housing.
