The figures you cite don’t seem to say anything about the fraction of people who stay in one place for ~15 years. Is it growing? Shrinking? The data you link says nothing, since it is just YoY mobility data. People moving in that year was at an all-time low. But this does not preclude, e.g. average five-year mobility for simultaneously being at an all-time high. This isn’t a problem, except that you so assuredly state that the parent comment is “factually incorrect” while not actually providing data that would back up that claim.
