So, given that the 300 million-th American resident appeared in the country of the USA at 6:45 AM (in my time zone).....
And given that another person becomes an american residnet every 11
seconds (on average)...
That would have made me number 300,002,040 or so if they were counting citizens (there were 142 of us, so there
might be a bit of a brawl if anyone else wants to make something of
Of course since they aren't counting just citizens, I'm actually number 274 million-th or so (back in 2000) for residency and probably near 260 millionth citizen or so.
