It is greater at the north pole.

Work Step by Step

We find the difference by finding the difference in the distance from the center of the earth, for we know that gravity is inversely related to the square of the distance from the center of the earth. Since the equator is further away from the center of the earth, gravity is greater there. We find the percent difference: $=\frac{\frac{1}{6378000^2}}{\frac{1}{6356000^2}}=\fbox{.68 percent}$
