I went to a salsa festival (Mumbai suburb) in 2018. So it had dancers from all over India. I was disappointed by the size(the whole festival has 200 people and there were probably 100-120 indians). There were a lot more men than women. Some ladies just watched until some organizers asked them for a dance. Social dance was very much influenced by performance type of dancing, I did not feel the real Latin music vibe. Most dancers were able to pick up soft leads (they were probably advanced beginner level). India has a great potential (meaning its usually fun to dance with indians). But they are not exposed to salsa and there are fewer women into it. I do not think its growing. Around the same time I went to another festival in Lebanon (which is a much smaller country) and they definitely had more people. Women were just as much interested as men were. Indian women are friendly (in fact most of my female friends are Indian), but I do not think salsa is popular in India. In most us cities, latinos start the events and we learn by watching them and then we fall in love with the music. That's not happening in India.
