It all depends on the society that the Covenant live in (which includes every species in the Covenant).
Humans used tend to group together where resources are plentiful. A whole society worked around that one thing as we depended on the work supplied by persons wanting to use that resource (or yourself using that resourse).
Nowadays, thanks to technology like water pipes, gas pipes and electrical cabling people can live anywhere quite easily. For work they can commute there using their car, so distance between work (dependant on it) can increase. This is how suburbs appeared.
I'm not too sure if Covenant society would be like this. Can you imagine lots of little pods for families of Grunts to live in on a long road? Anyway, there's bound to be persecution of the lower races like Grunts and Jackals by higher ranked species so I very much doubt there would be a mix in race. It would most likely that overall, each species sticks to the Planet they came from. The Covenant only come together in war. Species soldiers would be shipped from their planet of origin to an army randez-vous point. From then, they would be mixed to give a more versitile army.
Well that's my theory anyway
