Ten rival national top cities of the world

Most countries have one city which is clearly top of the pops. In particular, one city (which may not necessarily be the national capital) is usually the largest population centre and the main economic powerhouse of a given country. Humbly presented here is a quick and not-overly-scientific list of ten countries that are an exception to this rule. That is, countries where two cities (or more!) vie neck-and-neck for the coveted top spot.

Note: all population statistics are the latest numbers on relevant country- or city-level Wikipedia pages, as of writing, and all are for the cities' metropolitan area or closest available equivalent.


Natural disaster risk levels of the world's largest cities

Every now and again, Mother Nature reminds us that despite all of our modern technological and cultural progress, we remain mere mortals, vulnerable as always to her wrath. Human lives and human infrastructure continue to regularly fall victim to natural disasters such as floods, storms, fires, earthquakes, tsunamis, and droughts. At times, these catastrophes can even strike indiscriminately at our largest and most heavily-populated cities, including where we least expect them.

This article is a listing and an analysis of the world's largest cities (those with a population exceeding 10 million), and of their natural disaster risk level in a variety of categories. My list includes 23 cities, which represent a combined population of approximately 380 million people. That's roughly 5% of the world's population. Listing and population figures based on Wikipedia's list of metropolitan areas by population.


World domination by box office cinema admissions

It's no secret that Hollywood is the entertainment capital of the world. Hollywood blockbuster movies are among the most influential cultural works in the history of humanity. This got me thinking: exactly how many corners of the globe have American movies spread to; and to what extent have they come to dominate entertainment in all those places? Also, is Hollywood really as all-powerful a global cinema force as we believe; or does it have some bona fide competition these days?

I spent a bit of time recently, hunting for sets of data that could answer these questions in an expansive and meaningful way. And I'm optimistic that what I've come up with satisfies both of those things: in terms of expansive, I've got stats (admittedly of varying quality) for most of the film-watching world; and in terms of meaningful, I'm using box office admission numbers, which I believe are the most reliable international measure of film popularity.
