Every year, World Population Day is observed on July 11th, aiming to increase people's awareness of various population issues, such as the importance of urbanization, genderequality, poverty, health, and human rights. In 2025, under the theme "Empowering Youth to Build the Families They Want," the United Nations draws attention to the largest generation of young people in history, many of whom are coming of age in rapidly urbanizing contexts. Urban centers remain key to understanding these demographic patterns, as cities continue to attract populations seeking opportunity, stability, and access to essential services. Today, more than half of the global population resides in urban areas, a share projected to increase to 66% by 2050.
The Economist Intelligence Unit (EIU) has released its Global Liveability Index for 2025, assessing 173 cities worldwide across five categories: stability, healthcare, culture and environment, education, and infrastructure. This year, Copenhagen has taken the top position, ending Vienna's three-year run as the world's most liveable city. The Danish capital earned high scores in stability, education, and infrastructure, narrowly surpassing Vienna, which saw a decline in its stability rating following recent security incidents. The average global liveability score for 2025 remains steady at 76.1 out of 100, unchanged from 2024. While year-on-year improvements were recorded in healthcare, education, and infrastructure, these were offset by a continued decline in stability, driven by rising geopolitical tensions, civil unrest, and increased security threats in several regions.
The pursuit of an ideal city has long been a topic of debate among architects and urban planners. In addition to aesthetic identity and cultural heritage, the quality of life in every city represents perhaps the most important marker in this pursuit. This year, the Economist Intelligence Unit (EIU), a sister company of The Economist, has released its Global Liveability Index 2024, highlighting the cities that excel in this ongoing quest. For the third consecutive year, Vienna ranked as the most liveable city in the world. European cities Copenhagen, Zurich, and Geneva also rank high, attributed to their smaller populations, which contribute to lower crime rates and less congestion. In comparison with the 2023 ranking, the numbers for North American and Australian cities have been dragged down by the ongoing housing crisis.
The assessment ranks 173 cities from around the world. Each city is scored based on 30 qualitative and quantitative factors evaluating 5 categories: stability, healthcare, culture and environment, education, and infrastructure. The scores are based on external data points, in-house analysts, and in-city contributors. The category of stability has registered the biggest decline, as protests and armed conflicts increased in incidence. At the bottom of the cist, the city of Damascus, Syria, continues to be ranked as the least liveable city in the survey, followed by Tripoli, Libya, reflecting severe instability.
More than half of the world's population resides in urban areas, with over 4 billion people depending on cities as their main environment. According to the United Nations’ latest report on populations in cities, this number is expected to continue to increase over the next 50 years, prompting cities worldwide to strive to find better ways to accommodate their growing population while transitioning to more sustainable urban practices. To highlight this responsibility, the United Nations has declared July 11th the World Population Day.
Under this year’s theme, “To Leave No One Behind, Count Everyone,” the UN aims to also draw attention to the importance of data collection for reflecting societal diversity. The growth of world cities is part of this equation as an important measure for understanding global population trends. The following list presents the top 20 cities worldwide in 2024, ranked by the population size of their metropolitan areas. Comparing the results to the previous editions, the only cities to reduce their size are the two cities from Japan, Tokyo and Osaka. The highest growth rates can be observed in African mega-cities, Kinshasa and Lagos, while China continues to be the most present country in the list, with 5 metropolises present in the top 20: Shanghai, Beijing, Chongqing, Tianjin, and Guangzhou.
Under the titles of Optimism and Instability, this year’s global index score has returned to pre-Covid-19 days, highlighting that the world has fully recovered from the pandemic. Ranking living conditions in 173 cities based on stability, health care, culture and environment, education, and infrastructure, the survey suggests that nowadays, “life in cities is a bit better than at any time in the past 15 years”, although Stability scores dropped on average in 2023, due to worldwide clashes, political disruptions, social protests, inflation, and wars.
Global Finance's ranking of the world's best cities to live in, during 2022 has just been released. Centered on 8 different parameters that calculate and compare the quality of life of people living in urban areas such as economy, culture, population, environment, etc., this year’s edition also took into consideration Covid-19 deaths per thousand for each country, to reflect the new reality we live in. With data from the Global City Power index, Johns Hopkins University, Statista, and Macrotrends, the list seeks to have a complete vision, putting together traditional metrics with new factors.
Claiming the first position is London, U.K, a city that although didn’t get high rankings in its Covid-19 metrics, still topped the list, mainly due to its scores in culture, accessibility, and population growth. Tokyo was selected for the second position, showing weakness in one parameter, population, as its numbers have been declining for the past 10 years. Shanghai followed next, in the third position, because of relatively low Covid-19 death figures and strong population growth. Singapore and Melbourne came in 4th and 5th positions.
Vienna, the city with the best quality of life in the world.
Mercer, a consulting leader that helps other organizations around the world advance the health, wealth and performance of their employees, releases a survey annually that helps multinational companies and other organizations compensate employees when placing them on international assignments. Their survey for the year 2012 evaluates over 221 cities around the world on their quality of living with New York City as the base city and highlights several trends that can add onto what we as designers and urban planners believe makes a city successful and livable.
