Ichigo is part-Quincy because his mother was an Echt Quincy and his father was Human at the time he was conceived.

Ichigo has Shinigami powers inherited from his father.

He also has an inner Hollow inherited from his mother that fused with his Shinigami powers to become one source of power - he cannot draw on one alone.

He has, as of right now, latent Quincy powers in that the manifestation of his powers is the one who activated them, not Ichigo himself.

To sum it up, Ichigo is a part-Quincy Human with Shinigami and Hollow powers. Shinigami is not a race, and Ichigo most certainly isn't part-Hollow: he just has an inner one that gives him access to Hollow abilities (though only when it takes over his body, as of yet).

However, Ichibei did indeed state Ichigo has become a true Shinigami. This does not change his race; rather, Ichibei is acknowledging that Ichigo has grown enough temperament-wise to be considered a real Shinigami and not just a Substitute one.

So, to sum it up, Ichigo is a Human (as stated by himself, his father, and Nimaiya) with latent Quincy powers, currently accessible Shinigami powers, and an inner Hollow that has merged with his Shinigami powers to produce a unique entity.

Bottom line, he's a part-Quincy Human with the powers of two races and one profession.

Hope that helps. This is the best answer in this entire thread.
