Here are the top ten:

1 New York
2 London
3 Tokyo
4 Paris
5 Hong Kong
6 Chicago
7 Los Angeles
8 Singapore
9 Sydney
10 Seoul

Boston is number 19.

In Britain, the birthplace of the Industrial Revolution, there are only two cities with a population of more than 1 million; in the United States, there are just 10 such cities. But already in China, there are 43 cities of more than 1 million, and by 2030 there will be 221, the McKinsey Global Institute predicts.

Wow.

Lots of research (facetiously, I hope) has gone into how society would react to a as-of-yet theoretical attack.

Key quote:

If bureaucratic conflicts and organizational pathologies hamper effective counter-terrorism policies, imagine the effect they would have on anti-zombie policies. The bureaucratic turf wars would be significant. Quelling the rise of the undead would require significant interagency coordination. In the United States, one could easily envisage major roles for the Departments of State, Defense, Justice, Homeland Security, Transportation, and Health and Human Services. This does not include autonomous or semi-autonomous agencies like the Federal Emergency Management Agency, Environmental Protection Agency, Food and Drug Administration, Center for Disease Control, and the myriad intelligence agencies.

So the ability of organizations to adapt to an army of the undead is an open question. Clearly, further research in this area is desperately needed.
