Abstract: The sex market is expanding at an unprecedented pace and touching every strata of the society. Over the last decade thousands of Bangladeshi girls were lured under false circumstances and sold into the sex industries in different nations including Bangladesh. To analyze whether trafficking is the main direct pushing factor for engaging in sex trade and to find out the factors which influence the trafficking; we have conducted the study. Total 729 sex workers at Kandapara brothel, Tangail in Bangladesh were the targeted population of the study. A semi structured data collection instrument was developed and data were entered in Statistical Package for Social Scientist (SPSS) 12-version. We have found trafficking is significantly different as direct pushing factor than any other pushing factors; it is the main direct pushing factor for engaging in sex trade. Age, education, poverty or unemployment, marital status, geographical area and previous occupation influence trafficking for engaging in sex trade.
