The free-fall acceleration g increases as one proceeds, at sea level, from the equator toward either pole. The reason is

Earth is approximately an ellipsoid having its equatorial radius smaller than its polar radius by 21

Earth is a sphere with same density everywhere

Earth is a sphere with different density at the polar regions than in the equatorial regions

Earth is approximately an ellipsoid having its equatorial radius greater than its polar radius by 21
