Would a person weigh more at the pole than at the equator?

 I ask because it seems the centrifugal force would be greater at the equator than the the pole, effectively reducing the force of gravity at the equator. This question is assuming the Earth is a perfect sphere (which I know is not the case).

Assuming a spherical earth there would be a difference resulting from the earth's rotation. So yes, you would weigh slightly more at the poles than at the equator. 

Now for the earth as an oblate spheroid there is the same difference, plus you will weigh even less at the equator because you'd be farther away from the centre of the earth.
