I had a same question. Actually the sum comes closer to 110 million. But those were only the top three. PATH NY/NJ has other terminals - that were not listed.

Point is the many NY region airports are high on the list.

I am surprised Dallas (with so many runways) was not listed. My experience at night is Dalla/ FW sky have many planes simultaneousl. At one point I counted something like 20 in approach or departure at the same time.

Wouldn't O'Hare be Chicago (Chigo)?
I was thinking more of whole continents and hemispheres not on the map.

Yes, O'hare. I didn't notice my creative spelling of Chicago until it was too late to change it. :lol:

Bet you've wondered why...

Table #2 has the least popular reasons like, save my job, get a raise, and give someone an STD.

7,000 rivers...

Economic powerhouse and flood magnet.

Is that the world's biggest sanitary sewer system?

A great graphic of the most important engine of US development.
There was another here a ways back that showed all the major drainages.

A human on a bicycle (reasonably flat terrain, not like mountain goat Griff) is still the most energy efficient travel.

I've never traveled by bee

How about blowfly?

Income inequality decreasing, all income levels seeing improvements

Stupid question, but are they showing the 2000 incomes in 2015 dollars?

If not, incomes have effectively dropped by 5%, 16%, 17%,16%, and 17% from top to bottom. All categories going negative, but the "least" negative on the poorest quintile.

I guess the question for that lowest quintile is, "how well were the poorest people in the country doing in 2000, " followed by, "are they able to survive while doing 5% worse"? Five percent of a millionaire's income doesn't affect whether they can afford food/shelter/medicine, five percent of a poor person's income probably does.

Losing 16% of effective income for the person making 40 grand is *definitely* hurting them.

Flint is right. Change measured in percentage terms means very little when a loaf of bread costs the same for everyone.

All figures are corrected for inflation.
