Methods and apparatus to perform multi-level hierarchical demographic classification are disclosed. An example apparatus includes a neural network structured to process inputs at an input layer to form first outputs at a first output layer representing first possible classifications of an individual according to a demographic classification system at a first hierarchical level, and to process the first outputs to form second outputs at a second output layer representing possible combined classifications of the individual corresponding to combinations of the first possible classifications and second possible classifications of the individual according to the classification system at a second different hierarchical level; and a selector to select one of the second outputs, and associate with the individual a respective one of the first possible classifications and a respective one of the second possible classifications corresponding to a respective one of the possible combined classifications represented by the selected second output.
