LetS ⊂ℝ3 be ann-set in general position. A plane containing three of the points is called a halving plane if it dissectsS into two parts of equal cardinality. It is proved that the number of halving planes is at mostO(n2.998).As a main tool, for every setY ofn points in the plane a setN of sizeO(n4) is constructed such that the points ofN are distributed almost evenly in the triangles determined byY.
