1. A three-dimensional data encoding method, comprising:
generating a bitstream by encoding subspaces included in a current space including three-dimensional points,
wherein the generating of the bitstream includes:
encoding information that is common to the subspaces and includes first information and fourth information, the first information indicating first coordinates which are coordinates of the current space, the fourth information indicating a total number of the subspaces;
encoding second information indicating a difference between second coordinates which are coordinates of a subspace among the subspaces and the first coordinates; and
encoding third information provided on a subspace basis and indicating a size of a corresponding subspace among the subspaces, and
wherein a first subspace and a second subspace that are included in the subspaces can Partially overlap.
