AdMob recently released its Mobile Metrics Report for April 2010, and along with this they released a spreadsheet showing iPhone OS usage in their network broken down by country. While this raw data is by itself very useful for iPhone developers (e.g. we really should support French in the Nelso iPhone apps), I thought it might be interesting to see how these numbers compare to the populations of the various countries in which the iPhone is sold.
Thus, I've taken AdMob's numbers and divided them by the population of the country (using figures from Wikipedia) to arive at a rough estimation of iPhone OS penetration. Keep in mind that the real numbers will be higher than this - AdMob can only measure requests to its ad network. For comparison, AdMob claims approx. 10m iPhones in the U.S., while AT&T reports more than 15m iPhone subscribers on its network.
I haven't included every country in the report, just the top 20 and a few other countries that interest Nelso (e.g. Czech Republic, Poland, etc.). For the full list, grab a copy of the spreadsheet from AdMob's site (you'll have to insert the population numbers yourself, of course).
Singapore looks like the big winner here, with over nine percent of the population using an iOS device. Assuming these device numbers are low, and that 25% of the population is either under 15 or over 65, iPhone use among young(ish) men in Singapore must be impressive indeed.
