"LatinX" doesn't seem to be spreading all that much among Latinos, at least in the US [1].

76% of Latino adults say they haven't even heard of it, 20% have heard of it but do not use it, and 3% use it.

The most usage is by women 18-29, with 7% using it.

The majority say that if you need a non-gendered term of such people use "Hispanic".
