Why are Kannadigas not as common in the US as other Indian ethnolinguistic groups?

I’ve always wondered this. My p@rents are from Karnataka. I never really meet any Kannadigas here tho, at least in the DFW area where I grew up. I don’t really see them on social media either. I feel like they are one of the, if not, lowest % of immigrants from India to US. My f@mily and I are part of this organization just for Kannadigas, so I still know some of them, but if it wasn’t for that, I wouldn’t know any.

Do you know why this is? Sorry if this is a dumb question, I’m not the smartest
