Of the 30 factors within these categories, the qualitative ones are assigned as acceptable, tolerable, uncomfortable, undesirable, or intolerable by a team of expert analysts. The ranking attempts to assess which cities across the globe provide the best living conditions, by assigning a score on 30 quantitative and qualitative measures across the five categories with the following weightings: This map uses annual rankings from the Economist Intelligence Unit (EIU) to show the world’s most livable cities, measuring different categories including: stability, healthcare, culture and environment, education, and infrastructure. But as cities worldwide return to the status quo, many of these urban centers have become desirable places to live yet again. Pandemic restrictions changed the livability of many urban centers worldwide as cultural sites were shuttered, restaurant dining was restricted, and local economies faced the consequences.
Ranked: The Most and Least Livable Cities in 2022 Further, it will be even more interesting to see what role automation will play as the old-age dependency ratio hits historic highs. With the future demographic composition looking very different than today, it will be fascinating to see how the economy responds to these potential tailwinds. Global median age is projected to surpass 40 years by the end of the century, and it will be considerably higher in many Western nations, especially in Japan and Europe.
Over time, the shape of the world population pyramid is expected to shift from Stage 1 (high birth rates, high death rates) to something closer to Stage 4 (low birth rates, low death rates).Īs the population distribution skews older, here is how population size and global median age will change: Year The following graphic charts how these changes affect the makeup of the world’s population. Urban dwellers tend to have fewer babies-and by 2050, there will be an additional 2.5 billion people living in cities globally.įewer births combined with improving healthcare-especially in developing nations-will dramatically alter the composition of the world population pyramid, creating both economic opportunities and challenges in the process. First, this happened in the developed world, but as the century progresses this phenomenon will impact more and more developing nations.Ĭhina’s “One Child Policy” in particular had an effect on global population growth, and the aftermath of the policy is still contributing to a shrinking Chinese population over the long term. Why has population growth been dropping since the 1960s?Ī variety of explanations factor into this, including:īirth rates tend to fall as nations get richer. Today’s powerful charts come from Our World in Data by economist Max Roser, and they show how global demographics will shift over the next 80 years.īelow you can see one major catalyst of this change, which is the peaking (and then falling) population growth rate: In fact, according to the most commonly cited United Nations projection, which is based on a medium fertility rate scenario, it’s expected that annual population growth could drop all the way to 0.1% by the end of the 21st century. The world is in the midst of a notable period of demographic transition.īack in the 1960s, global population growth peaked at a 2.1% annual rate, but since then it has been on a historic downtrend.
