Abstract
The contribution of massive fermions and topologically massive gauge fields to a Chern-Simons term for the graviton is computed to one-loop order in three dimensions. Invariance under large coordinate transformations places restrictions on the number of these massive matter fields. The parity anomaly for massless fermions is determined, and a possible parity anomaly for massless gauge fields is suggested.
