Roma includes wide variety of communities from eastern Europe. For example, Roma, Sinti, Kale, Dom and Lom and wide diversity of tribes who call themselves gypsies. (Alan Anstead)
There is wide range of Romani groups. For example, Bergitka Roma, Polish highlanders, Roma and traditional nomadic groups such as Polska Roma, Lovara, Kelderani etc.
For many years Roma people have lived in different societies with different cultures. Romani have always been living as a minority population and hence their culture is vanishing as a result of cultural separation from majority groups they live in.
A strong internal structure, habit of living in a group and rules create a big boarder between Roma and non-Roma people.
Even though it may look like it, Roma people are not insensible to their surroundings.
Will guy: “Romani culture as such, understood in a broad sense,
is not a unique and isolated entity, in spite of it’s characteristic elements, but rather arises out of and is a response to the nature of the symbolic relationship between Roma and the wider majority communities on which they have always depended for their livelihood” (Guy 2001)
