I think Endless Legend, also made my the Humankind devs Amplitude, was the first to introduce districts. Granted, the bones of 4x games, in general, are based on Civilization 1, at the very least.

A parasite, you say?

I guess a weak jobs report here is also part of it?

I can see it looking like that, but I’m pretty sure it’s because BD-1, the little mini droid you run around with, is up on his shoulder obscuring part of the arm/hand area.
