The reasons of floating population between Han nationality and minorities have a difference. Using the data of 1% population sample survey in 2005, this article mainly concerns on whether the nationality factor infects this difference. The nationality factor includes two criteria, i. e. whether the floating people is minority and whether they come from minority autonomous region. Based on these criteria, the floating people are divided into four types, in which three types are selected as contrast sample, and further as independent in regression, and the reason of people floating is consider as dependent. The logistic regression model shows that nationality factor infects the difference about the reason of floating between floating minorities and Han indeed.
