What are some examples of segregation?

The Latin phrase 'de facto' means in fact. In the Word-by-Word translation, the preposition 'de' means 'from, of'. The noun 'facto' means 'fact'. In its application to segregation, the phrase therefore refers to a separation that exists in reality, not according to the law. One example of 'de facto' segregation may be the description of the city of Montreal, in the Canadian province of Quebec. The city has an international culture. But some neighborhoods and some parts of the city may be described as segregated 'de facto', into separate English and French speaking residential and business areas.
