Our World in Data's vaccination dataset uses the most recent official numbers from governments and health ministries worldwide. The population estimates used to calculate per-capita metrics are all based on the last revision of the United Nations World Population Prospects.
With the widespread rollout of COVID-19 vaccines globally, some countries have started to consider mandatory vaccination, although no country has yet to make vaccines mandatory for its population. While COVID-19 has resurfaced the debate on vaccination policies, it has been an important topic for many other diseases. The World Health Organization (WHO) estimates that vaccines save two to three million lives each year (excluding COVID). The development of vaccines against vaccine-preventable childhood diseases has been a key driver in the decline of child mortality.
While a global pandemic has been a looming risk for decades, COVID-19 has come as a shock to society, health systems, economies and governments worldwide. In the midst of extraordinary challenges and uncertainty, and countless personal tragedies, leaders are under pressure to make decisions on managing the immediate impact of the pandemic and its consequences, decisions that will shape the state of the world for years to come. What might be the silver linings in the crisis and how might leaders use this moment to build a more prosperous, equitable and sustainable world?
The COVID-19 crisis and the political, economic and social disruptions it has caused have exposed the inadequacies of our current economic systems. Amid global concern for lives, livelihoods and the planet, leaders find themselves at a historic crossroads for shaping the recovery, and have a window of opportunity to reset economies on a new trajectory of more inclusive and sustainable growth. Following a brief review of the most recent developments, this edition of the World Economic Forum Chief Economists Outlook sets out a highlevel agenda for a path forward on three key emerging challenges: retooling economic policy to reduce inequality and improve social mobility; identifying new sources of economic growth; and aligning on new targets for economic performance.
The European Union and the United States have both been deeply affected by the coronavirus outbreak. The two contribute equally to the world economy, each accounting for about 16% of global output. A key difference is that the EU is home to about 100 million more people than the U.S. But Americans have lost significantly more jobs than their EU counterparts during the COVID-19 downturn.
One factor in play is that while countries across the EU deployed significant employment retention schemes, the U.S. focused on stimulus checks and unemployment compensation in lieu of job retention.
COVID-19 has disrupted all forms of human mobility through the closing of national borders and halting of travel worldwide. Preliminary estimates suggest that the pandemic may have slowed the growth in the stock of international migrants by around two million by mid-2020, 27 percent less than the growth expected since mid-2019, according to a report by the United Nations.
Growth in the number of international migrants has been robust over the last two decades, reaching 281 million people living outside their country of origin in 2020, up from 173 million in 2000 and 221 million in 2010. Currently, international migrants represent about 3.6 per cent of the world’s population.
Published since 1962, PRB’s annual World Population Data Sheet tracks global population data. This year’s edition provides 24 population indicators for more than 200 countries and territories. Users can also explore key trends through an interactive map.
“As the experience with the COVID-19 pandemic has shown us, population changes such as aging and rapid urbanization are important factors for countries to consider as they plan for future disease outbreaks, long-term health care needs and other developments,” said Jeff Jordan, PRB president and CEO. “PRB’s World Population Data Sheet provides objective data and analysis policymakers need to make these decisions.”
Population in the world is currently (2020) growing at a rate of around 1.05% per year (down from 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current average population increase is estimated at 81 million people per year.
Annual growth rate reached its peak in the late 1960s, when it was at around 2%. The rate of increase has nearly halved since then, and will continue to decline in the coming years.
World population will therefore continue to grow in the 21st century, but at a much slower rate compared to the recent past. World population has doubled (100% increase) in 40 years from 1959 (3 billion) to 1999 (6 billion). It is now estimated that it will take another nearly 40 years to increase by another 50% to become 9 billion by 2037.
