I'm going to tap out on this one.
Here you have from your link https://www.fairus.org/issue/illegal-immigration/2020-how-many-illegal-aliens-us:
And New York Times states with Trump's wall and covid:
The number was similarly high for the 2000 fiscal year, when border agents caught 1.6 million people, according to government data.
Yet a link they give: https://www.cbp.gov/sites/default/files/assets/documents/2021-Aug/US59B8~1.PDF
I'm not going to bother looking for the correct numbers.
The Times says 1.6 million for 2020 but their link says 400,651.
That seems more likely going on 35,000 a month as graph at top.
