The vast vast vast majority of videos don't back this up. Not too many women either. Mostly young men 18-30. These are the ones lined up for processing by Border Security.

If you're getting your information from videos - rather than reading it - you're pretty likely to be getting an incomplete picture in general. Just as a rule of thumb, on almost any topic. Video can only give you an anecdotal snapshot, rather than incorporate all data about a subject. And because it's only a snapshot, you run the risk of getting a skewed view of the subject. That's the reason why perceptions about the Gaza conflict right now show a marked skew among people who get most of their information from videos on Tiktok, for example - they're just seeing image after image of things you can take new videos of (destruction in Gaza) rather than things you can't (like, say, hostages).

Anyway, here's a link to the complete demographic information:

cbp.gov - Southwest land border encounters

You can see the proportion of families rising year after year - the most recent figures have single adults travelling alone at 51% of the total, and families/unaccompanied children making up the remaining 49%.

This shift really dates back to 2019, though. The current CPB website with the graphs only goes back to the beginning of the Administration - but the below link has the info in data form. In 2018, the CPB apprehended 239K single adults and 107K family unit members. In 2019, those figures were 302K single adults and 474K family unit members. A complete reversal in the demographics of the border. COVID disrupted that pattern a great deal, but we see it in today's figures as well. During the Obama years, family crossings were invariably less than 100K - they haven't been less than that since.
