Intimate Partner Violence Among International and Interprovincial Migrants: A Population-Based Analysis of Canadian Linked Immigration and Justice Data

Abstract

Factors associated with IPV among immigrant women are not well understood. Using linked immigration and justice data, we compared the incidence of justice-identified IPV (JIIPV) among 58,564 international immigrant women born outside of Canada, 30,098 women born in other Canadian provinces (i.e., interprovincial migrants), and 88,662 long-term Manitoban resident women. International immigrant women had the lowest incidence of JIIPV compared to matched long-term Manitobans (adjusted hazard ratio (aHR) 0.49, 95% CI: 0.43–0.56) and interprovincial migrants (aHR 0.56, 95% CI: 0.43–0.73). Among immigrants, JIIPV varied substantially according to birthplace, increased with length of residence, and was less frequent among secondary immigrants.
