Let me get you the statistics for the US market: Education 3811 Entertainment 3587 Photo 562 Music & Video 1012 Health & Fitness 867 Security 134 Tools 2387 Government 111 Shopping 179 Games 3657 Lifestyle 1292 Food & Dining 754 Business 708 Travel 1050 Social 523 Finance 360 Productivity 1154 Sports 816 News & Weather 1598 Books & Reference 3158 As you can see there are only 111 'government' apps for example. Since the list of 'top x apps' only contains 100 entries, you're pretty much guaranteed to be in the top 100 of government apps when you make one (it can be anything, an app for a political party, an app for polls, etc.). The same goes for 'shopping' and 'security' (and a little bit for finance, which has 360 apps). Edit: here are the stats for the different 'games' subcategories: Action 183 Adventure 72 Arcade 512 Card 167 Casino 73 Family 258 Kids 390 Music 27 Puzzle 1269 Racing 33 Role playing 48 Shooter 92 Simulation 54 Sports 71 Strategy 203
