 So, the research I've presented at this conference is trying to solve a simple problem, which is trying to come up with an estimate of the number of people moving from one country to another country in the Asia Pacific region in, again, a given year. And the problem is we're looking at 53 countries and migration from one country to another. And of those 53 countries, only four provide any type of kind of data, what we would call a migration flow. Other countries provide some information, partial information such as labor flows, but none of it is complete. So, our project that we're presenting here is trying to, basically, is presenting our first attempts at coming up with a complete picture of the movements across a very big region in the world so that we can understand the impacts of migration better. The four countries are Japan, South Korea, New Zealand, and Australia. And all four of those countries have excellent administrative systems to gather information on migration and entries and exits. The problem is they're not the major senders or receivers within the region, and they're not necessarily a kind of a typical country within the Asia Pacific region. So, one of the challenges, although those countries provide really good data, is how do you translate those experiences to other countries? And so, we really need big countries like China and India to gather information as well as a lot of other Indonesia, Philippines, Pacific islands. You name it, if any country could do better, it would help our understanding of migration. My view is really the best way to improve the situation on migration is to improve the administrative data collection systems, either for border control, censuses, registers, and so forth. We have strong population registers and really strong interconnected administrative data systems. So, those are, and I think all countries are moving in that direction and we will get there. It might take some time for countries that don't have many resources or expertise, but really for all sorts of ranges, even beyond migration, having good information on their populations and how their health care systems, the tax registers, and also enabling them to count how many people there are. But yeah, for migration data perspective, countries that have good population registers that pull information from lots of other administrative registers in the country have the best information.
