It shall include such other information as is required by sections 79-524, 79-528, and 79-578, except that the information required by sections 79-524 and 79-578 as to children under five years of age may be limited to the number of children by age level and shall not include the names of all the taxpayers in the district. The board may, at its option, establish a permanent and continuing census or enumeration of school children.
