The cultural aspect
Bhangra dance has become an international dance that appeals to all kinds of audiences. There is an aspect of Bhangra, which makes it suitable for ethnic minorities and that include people from Pakistan and India in particular. However, I have learned that even people from the Middle East and Turkey are interested in Bhangra fitness as I am contacted by these nationalities very often.
The reason is that Bhangra is a cultural dance which is danced to all kinds of festive occasions, particularly weddings and parties. Many immigrants are therefore motivated to learn Bhangra dance.
As regards the older group of Pakistanis and Indians in Denmark and other countries, they used to live in the Punjab region, where Bhangra dance originates from. For this reason they are more interested in Bhangra music and dance, than other dance styles like Bollywood or Zumba.
