"In 2010, 15.1% of people in Australia aged 14 years or older were daily smokers, declining from 16.6% in 2007. Between 1991 and 2010, the proportion of daily smokers declined by almost 40% to the lowest levels seen over the 19-year period (Table 3.1). The proportion of people who had never smoked increased. Also:
"• the number of people smoking daily in 2010 decreased by approximately 100,000 people (2.9 million in 2007 down to 2.8 million in 2010)
"• just under one-quarter of the population (24.1%) were estimated to be ex-smokers and more than half (57.8%) had never smoked in their life in 2010
"In 2010, those people who had never smoked (10.6 million) and those who were ex-smokers (4.4 million) far exceeded the number of smokers (3.3 million) aged 14 years or older."
