The human species is on the transfer. Final yr there have been extra individuals dwelling exterior of their beginning international locations than at another time in fashionable historical past, in response to the United Nations. It’s a sea change that can reshape politics, economics and civil societies for generations.
It’s no coincidence that 2024 was additionally a yr of defeat for incumbent political events, as chief after chief was voted out of energy in democracies on the heart of the human storm.
This nice world migration is a staggeringly complicated phenomenon with numerous causes and implications. But maybe no different problem is as urgent and as little understood by the typical citizen and policymaker alike. Authorities data differ wildly from nation to nation, surges in unlawful immigration are sometimes solely evident looking back and data isn’t collected in any respect in some corners of the world. As is the case with so many different issues, we don’t even know what we don’t know.
Till now. Within the maps under, Occasions Opinion can present the clearest image thus far of how individuals transfer throughout the globe: a document of everlasting migration to and from 181 international locations based mostly on a single, constant supply of data, for each month from the start of 2019 by means of the top of 2022. These estimates are drawn not from authorities data however from the placement knowledge of three billion anonymized Fb customers everywhere in the world.
The evaluation — the results of new analysis printed on Wednesday from Meta, the College of Hong Kong and Harvard College — reveals migration’s true world sweep. And sure, it excludes enterprise vacationers and vacationers: Solely individuals who stay of their vacation spot nation for greater than a yr are counted as migrants right here.
The info comes with some limitations. Migration to and from sure international locations which have banned or restricted using Fb, together with China, Iran and Cuba, isn’t included on this knowledge set, and it’s inconceivable to know every migrant’s authorized standing. However, that is the primary time that estimates of world migration flows have been made publicly obtainable at this scale. The researchers discovered that from 2019 to 2022, an annual common of 30 million individuals — roughly one-third of a % of the world’s inhabitants — migrated annually.
If you need to see the information behind this evaluation for your self, we made an interactive software that you should utilize to discover the complete knowledge set.
As a substitute of arguing over immigration with stunning anecdotes and distinctive incidents, our debates ought to begin with a useful resource like this one — high quality data, gathered with a constant process internationally — a supply that enables us to take a step again and see the massive image.
As these maps show, if we glance intently sufficient, so a lot of our assumptions in regards to the grand form of world migration are incomplete. Little question there’s something uncomfortable about the truth that a handful of tech firms — Meta, Google and TikTok — might have extra knowledge about human migration than the United Nations or any particular person authorities. But, if these firms are going to proceed to gather this knowledge, then on the very least the general public also needs to profit from it. Meta has taken a laudable step with this preliminary public launch, and we must always anticipate researchers to construct on it.
When disruption hits a rustic — an financial crash or growth, a civil conflict, a contagious virus, a pure catastrophe amplified by local weather change — a pure response is migration. Our second calls for higher instruments to assist us extra clearly see these ripples within the currents of humanity.
The selection isn’t merely between open and closed borders, asylum and amnesty or disappearances and deportations. This image of migration is one through which all nations, wealthy and poor, take part in an excellent community of human motion, linked by cultural, financial, historic and household ties, and put into fixed movement by fears and goals, one life at a time.

Methodology
The estimates come from the Social Capital Analysis Staff at Meta and are based mostly on knowledge from three billion anonymized energetic Fb customers. They don’t embrace knowledge from different Meta merchandise like Instagram or Whatsapp.
The info consists of estimates aggregated on the nation stage for 181 international locations, which account for 79 % of the worldwide inhabitants. There are some international locations not included within the estimates, comparable to China, Cuba and Iran.
An individual is taken into account to have migrated if she or he resided in a rustic for one yr, then migrated to a different nation for one more yr, permitting for 60 days of journey. Fb utilization isn’t randomly distributed, so estimates are reweighted with per-capita nationwide earnings and Fb penetration charges.
The researchers additionally added noise to those statistics to make sure privateness in nation pairs with a small variety of migrants. The quantity of noise added to every remark was small; in 95 % of instances, the estimated stage of migration in a month modified by fewer than seven individuals.
Estimates have been evenly rounded. Summed totals could also be barely completely different from the uncooked knowledge set.
