In the 2009 Citizenship Survey, what proportion of people identified as Muslim?
4%.
After Christianity, Islam was the largest religion recorded in the 2009 survey, at 4% of people. The figure is small but distinct, and it comes up often because the survey listed the faiths in a neat descending order: Muslim 4%, Hindu 2%, Sikh 1%, then Jewish and Buddhist below half a per cent.
Test Trap. the Muslim figure (4%) is often confused with the Hindu figure (2%). Remember the halving ladder: 4, 2, 1.
Why it matters: A known trap: candidates mix up the Muslim (4%) and Hindu (2%) figures.
Memory hook: Halving ladder: Muslim 4, Hindu 2, Sikh 1. Each step down halves the number.
