The only fact I've stated is the huge difference between the urban and rural areas, which is not wrong. The rest is opinion, (hence my use of words like "seems to" "I think" "probably" and as the source uses, "appear to"). While I could talk gravitational theory all day, honestly, I have a hard time understanding the math involved to produce this number, and am merely trying to take it at face value, as I believe many others will. Perhaps a less ambiguous line that puts the statement into context would help. I'll leave that to smarter people than myself and simply try to help provide some of that context. Other than making sure there is no confusion on the matter, (like mine), my only other objection is that of notability, and I'm standing right on the fence on that one, as I believe the number in itself does not merit inclusion or exclusion.
