Abstract: With the increase of number of migrants，adding absence of basic support and administration，more and more unwanted pregnancy beyond family planning，premarital pregnancy，and induced abortion were taken place among migrant population，which not only impacted on the family planning service，but also had some negative impact to sexuality and reproductive health of migrants. The use rate of IUDs and condom are relatively higher than the urban population，but the knowledge of contraception and birth control is still low； married women migrant of childbearing age were with a higher score of attitudes towards domestic violence than women in rural. Most women migrants could accept the attitudes towards husbands' beating of their wives. Compared with urban household population，their leisure lives are large differences among migrant population. Thus it can be seen that current status of contraceptives and family planning among migrants are not optimistic，and the current situation of contraceptives among migrants might be associated with inadequate knowledge related sexuality and reproductive health，low economic status，low accessibility of family planning and reproductive health related services. Therefore，the author brought corresponding suggestions and measures in order to improve the sexuality and reproductive health among migrants in China.
