You've had the bullshit story from Crawford, now for the facts...
Don't know where to begin really...
Population
Amsterdam city: 870,000
urban area: 1.4M (Amsterdam has a Greenbelt)
metro area: 2.8M
Randstad: 7.3M (comparable to a CSA, but way smaller in area. Almost perfectely analogous to the Bay Area in population and both being multi nodal with a clear primate city).
Economy
Amsterdam-Randstad has a $450bn economy (2017) which is about the same as Houston and (significantly) bigger than Philadelphia ($430bn), Boston ($423), Atlanta ($363bn), Seattle ($330bn), Miami ($328bn) and Detroit ($253bn).
There are 7 Global 500 companies in the city and a total of 14 in the Randstad area. Compare this to Houston which has 5, Atlanta, Chicago and Dallas 4 each, Seattle has 3, Boston, Detroit and San Francisco 2 each, LA, Miami and Philadelphia 1 each.
As a matter of fact, the only cities in the world with more G500 companies than Amsterdam are Tokyo, New York, Beijing, Paris, London, Seoul (8), Shanghai (8), Zurich (8) and Silicon Valley (9)!

Amsterdam Schiphol is Europe's 3rd busiest airport behind London and Paris, having recently overtaken Frankfurt (and regained its position over Istanbul and Madrid). Worldwide it's in the 12th spot. Amsterdam also has the most intercontinental connections after London, Paris, Frankfurt and perhaps Dubai.
Amsterdam is the 4th busiest port in Europe in its own right, nearby Rotterdam which is part of the Randstad metropolitan area is by far Europe's biggest and 7th in the world. The whole port system of the Rhine-Meuse-Scheldt delta (incl Antwerp) is probably stil 3rd behind the Yangtze river delta and PRD.
Amsterdam is the co-seat of the world's 7th stock exchange. (The first formal stock exchange was started in Amsterdam afterall).
One of the
Big Four Auditors is located in Amsterdam. The other three are in NYC and London.
Cultural
Amsterdam has 3 of the top 100 most visited art museums in the world (Rijksmuseum, Van Gogh Museum, Stedelijk Museum). The only cities that have more are London, Paris, New York, Washington and Barcelona (and Barcelona has lower total attendance). Madrid also has 3. (There's also a dependency of the Hermitage Museum in Saint Petersburg in Amsterdam).
Amsterdam has the world's biggest electronic music festival (sorry Miami).
Amsterdam has 2 universities inside the city limits, a total of 6 in the Randstad. All 13 Dutch universities are in the global top 200 (THE-QS) or in the global top 500 (ARWU) btw.
18 million tourists visited Amsterdam in 2016. I'm not going to look it up now but that probably puts it in the global top also.
Political
Amsterdam is the capital of the 8th trading nation in the world and of one of the top 20 economies. And while the government resides in nearby The Hague (part of the Randstad metro area), many NGOs are HQed in Amsterdam, Greenpeace and World Press Photo to name a few.
I'm not listing all this to be a city booster or a homer, just to show that Amsterdam is indeed a major globally connected city. Also not to take away from other cities which each have their own strenghts and merits. As opposed to Crawford who has bashed, insulted and spread lies about just about any city not named NYC on this forum I'm a true city lover.
