But anyway, the male-to-female ratio is...

Usually it's 100:105, and in severe age groups it's 100:110, but I heard international marriage accounts for about 9%. Isn't that a golden balance? People just can't practice self-objectivity, so they talk about being "leftover men" and fail to get married. If people could practice self-objectivity, I think a 10% international marriage rate would be the optimal setting.
