Those are comparing metro areas to cities, though. The DC one, for example, includes exurban areas and literal farmland in its definition of the DC metro area (which comes from the Census). This is the kind of stuff it includes: https://maps.app.goo.gl/kbfrPLDvBaUn7tzo8 https://maps.app.goo.gl/kbfrPLDvBaUn7tzo8 I don't think it's quite a fair comparison to compare that vs. Hong Kong or Singapore, especially when the London exurbs are called out separately. I'd guess that NYC is in the same ballpark of unaffordability and congestion as London, but the deeper suburbs / exurbs of NYC are cheaper than their British equivalents. I'd also wager that DC proper is cheaper than both NYC and London, both via absolute terms and income relative terms.
