I'm calculating total addressable market for a business that has to do with immigration. I need to know how many people physically relocate to another country with intention to settle there permanently, or alternatively how many people acquire legal immigrant status in a foreign country in a year, something like that.
OECD's website calls this permanent immigrant inflows, for 34 OECD countries they estimate it at about 4M a year, but I need data like this for worldwide. Is there a way to find it?
