"“….the past decade has seen unusually slow growth in immigration. In fact, the period from 2012 to 2022 saw slower growth in the immigrant share of the population than the 2000s, 1990s, 1980s and 1970s. You have to go all the way back to the 1960s, when the immigrant population actually shrank, to find a lower growth rate.”"

I think the numbers quoted are for LEGAL immigration, not migration followed by asylum requests.

Migration followed by asylum requests, which, is not legal immigration but legal asylum are not counted.

Migration followed by asylum requests is at an all time high of 30,000 per month.
