There are countries that decline in population even though they try to offset it with immigration, Japan is ahead of everyone in that.
But every time someone talks about the decline in population they usually aren't afraid of people going extinct, they are afraid of working hands supply going low imo ๐
You mean, the rest of the Asia has gone below even further? Also, birthrate isn't the only factor, and birthrate of Japan is highest among developed Asian countries, it's not highest overall
