> This outflow can influence this data

Influence how? Migrations from wealthy to poor regions are still migrations, no?

The graphic seems vague and not particularly revealing.

There's a quote from one of the study authors:

  "Because previous estimation methods relied on coarse five-year snapshots, 
   they yielded very few data points and created the impression that the rate 
   of global migration flows was stable," adds co-author Guy Abel, a research 
   scholar in the Migration and Sustainable Development Research Group of the 
   IIASA Population and Just Societies Program and professor at the University 
   of Hong Kong. "Our annual data provides a clearer picture, revealing that 
   this rate has actually risen since 2000. This upward trend appears to be 
   driven by long-term demographic shifts and economic development rather than 
   sudden, isolated crises."

So if I'm following correctly, when you look at coarse data, you miss a lot of the smaller-scale migration, and that small-scale migration pushes the totals up a lot?

I think people underestimate how many people move back to their home country once they have a better chance (through e.g. education or money) and / or when the situation there improves (e.g. stability). It's why I don't understand why the anti-immigration parties don't do more internationally to help other countries.

The Gulf states take in a lot of migrant workers, who have basically no labour rights there.

"The UAE hosts some 8.7 million migrant workers – equivalent to over 80 per cent of the country’s resident population – making it one of the largest foreign labour-receiving countries in the world. With Emirati nationals mainly employed in the public sector, migrant workers constitute the bulk of private sector employment"

In America at least, all the hot deserty places between Europe and India=Middle East. I only started hearing the term "South Asia" to refer to places like Pakistan after encountering more non-Americans online. Afghanistan is also considered as part of the Middle East to basically every average American (hence why it's lumped in with all those "Middle Eastern wars"), but I'm not sure if it's seen that way in other areas.

Pakistan being “south asia” makes about as much sense as Turkey and Saudi Arabia being labeled “west asia”. Technically correct, odd choice for modern communication.

Bangladesh is Muslim though

You have a funny way of spelling "sad" my friend.

"fleeing" and "replaced" are loaded terms, I don't think you can derive that from this data. That said, there's a lot of workers being imported from Asia to the middle-east for their ambitious construction projects, could that explain it?

> Meanwhile the middle-east population is fleeing and being replaced with asians?

Persians brought Hinduism to India, so maybe they're returning the favour

Options -> change projection helps a little bit.

Data quality issues usually get worse the further back you go.
