Twitter doesn't release detailed statistics about its usage, but it does permit third-party companies to tap into its API so they can conduct their own data mining. One such company, PeerReach, released some fascinating stats about Twitter usage for the month of October:

• 904 million registered accounts
• 232 million monthly active users
• 117 million monthly active tweeting users
• 45 million daily active tweeting users

What's more PeerReach found that Twitter has more users in Indonesia than in the UK. You can learn more about the demographics and location of Twitter users in BI Intelligence reports, here and here.
