You're presumably reading the graph of the % of population polled every year who say "they've been exposed to sex offences"(not necessarily in that specific year), not the actual yearly crime rates, which are lower down and which state: "In 2015, a total of 18,100 sex offences were reported; this is an 11 per cent decrease as compared with 2014. The number of rapes reported to police decreased by 12 per cent to 5,920 between 2014 and 2015. Reported offences regarding sexual molestation and sexual coercion, exploitation etc. also decreased to 8,840 (-8 %) and 1,430 (-6 %) respectively. "
