Methods A stratified cluster sampling method was used to survey the floating population in 4 different industries in Jianggan District, Gongshu District and Xihu District of Hangzhou.

The median urban mobility, industrial mobility and unit mobility were 0.40 and 0.33, respectively (Χ2 = 16.1, P <0.001). There was significant difference in the rate of awareness of AIDS among different groups of people (χ2 = 16.1, P <0.001) χ2 = 22.5, P <0.001). 5.5% (109/2 000) and 4.4% (52/1 171) had interim and commercial sexual behaviors respectively, of whom 30.3% (33/109) and 40.4% (21/52) respectively, with 12.8% (14/109) and 9.6% (5/52) of never-before users and 47.7% (52/109) of the most recent single-time users.
