Undocumented immigration to the USA

Factual Questions
1

Looking for facts from a reliable source.

How many undocumented immigrants came to the USA during Trump’s Presidency.

And how many during Biden’s Presidency?

I doubt the exact number is known, but a reasonable ballpark estimate will do.

Let’s not nitpick the terminology. The phrase “came to the USA” includes those who were already there under a legal visa, and who stayed when their visa ran out. Or similar things.

This is FQ. Just the facts, no political commentary. Cite the source, and why we should believe it is a reliable one.

MPI estimates there were about 11.2 million unauthorized immigrants in the United States in 2021, up from 11 million in 2019. The unauthorized population was largely stable in size from 2007 to 2021. Since then, the population has likely increased due to the large number of border arrivals post-pandemic, although more recent data are not available. The size of the unauthorized population is affected not only by arrivals, but also by departures, deaths, or in certain cases adjustment to a legal status.

DHS makes some effort to estimate the number of visa overstays per year. There is a Congressional Research Service Report here that has some data from FY2016 to FY2022 (there was no FY2021 report and the FY2023 report doesn’t look like its out yet).

It’s hard to compare, I think, because there’s only one Biden year of data (FY2022). But in FY2022, they estimated ~850,000 overstays (3.7%). If you average the Trump years (call it FY2018-FY2020), you’d get an average of ~675,000 per year (and an overstay rate around 1.5%).

Of course, any such statistics also hav to take into account about half a year of Covid restrictions. What were the restrictions on the border and how much did that impact the numbers during that time and for that year?

Yep. Basically Covid allowed trump to cut down the numbers allowed in. However, those are documented.

What we know about unauthorized immigrants living in the U.S. | Pew Research Center.

The unauthorized immigrant population in the United States reached 10.5 million in 2021, according to new Pew Research Center estimates. That was a modest increase over 2019 but nearly identical to 2017.
