More than one-third of foreign nationals in Ireland have been harassed on the street, according to a survey being published today by the Economic and Social Research Institute.
The think-tank says 32% of foreign nationals involved in the study also said they had been insulted and harassed at work.
Black Africans experienced the highest levels of racism among the groups surveyed.
Meanwhile, a separate study today from the Equality Authority says female migrant workers are experiencing widespread discrimination in the workplace.
The research, which is based on interviews with 36 migrants from 19 countries, says they have experienced under-payment or non-payment of wages, unethical recruitment practices and breaches of their entitlement to a contract, as well as harassment by employers.
It also says many are working in jobs below their skills level, with some of the women employed as cleaners or housekeepers despite having university degrees.
