That is normal. If you live anywhere that is populated by a particular race, you would expect that.Let's say we all live in Beddington, Maine which is 94% White and doesn't even list a Black population the number is so insignificant.
Statistically you could go out every day for what, more than 3 months without ever encountering a Black person, if then, let alone interact with them. In fact, I'm sure it's quite possible that you may never encounter me, the one black person in Beddington depending on schedules, places we each frequent, etc. (remember, this is a hypothetical).
While I, on the other hand am guaranteed to encounter one or more white people every single time I go out, whom I may interact with or not (the people at the store, gas station, restaurant, etc. are not the kinds of interactions I'm speaking of). I'm talking about instructors, co-workers, friends, colleagues, associates, brothers-in-arms, etc.
Did that help clarify things.
