Estimates based on DEICS-COL-2016 and DEICS-COL-2017. CIs estimated using a normal approximation. 1697 observations per year, representing 1 733 316 smokers. (*) denotes statistically significant difference between both waves at 10%, 5% (**) and 1% (***), using a two-tailed test for comparison of two proportion populations with no sampling weights.
COL, Colombia; DEICS, Demand for Illicit Cigarettes Survey; PIC, penetration of illicit cigarettes; PIC-C, PIC as the proportion of the consumption of cigarettes; PIC-I, PIC as the proportion of individuals (smokers).
