How does India calculate its local happiness caps?

[Kintara]

When I start an Info Era game, I start with the first two happiness buildings. India only gets +3 local happiness from this, even though I start with five population. Does anyone know how this works?

Edit: I noticed this prior to the beta patch with BNW.
Edit2: I think their cap is basically 1/3 lower than normal. It's a rather opaque rule, though. I wish the game tracked local happiness better.
