Let n be an even positive integer and F be the field GF(2). A word in F<sup>n</sup> is called balanced if its Hamming weight is n=2. A subset C ⊆ F<sup>n</sup> is called a balancing set if for every word y ∈ F<sup>n</sup> there is a word x ∈ C such that y + x is balanced. It is shown that most linear subspaces of F<sup>n</sup> of dimension slightly larger than 3/2 log<inf>2</inf> n are balancing sets. An application of linear balancing sets is presented for designing efficient error-correcting coding schemes in which the codewords are balanced.
