well i don't know the numbers, but there were many many thousands of DSLRs sold in Singapore in the past couple of years.
naturally it would be logical to assume that many more Singaporeans are DSLR owners with each passing month.
With a fancy new toy (of course one that costs a significant amount of $$ too), you'd naturally be tempted to bring it out as often as possible, to take photos of funny moments with your friends, and perhaps make them envious that your DSLR can capture much better shots than their 8 megapixel 'wonder phones'
* i think this explains about 80% of the occurences of ppl with DSLRs around town
