Spanish to English Social Sciences Social Science, Sociology, Ethics, etc. migration

This is from a report on migration and how migrants integrate into the host society and challenges to that happening smoothly.

The text lists aspects that the native population of the host country and migrants might differ over culturally and talks about awareness of identity... and then: "Siempre que se cuestiona la identidad de un individuo o de un colectivo es a causa de un conflicto, de un cambio, o de un encuentro diferencial."

Thanks very much.
