A federal survey of public schools has been updated, but certain data is missing. Information about bullying based on gender identity is no longer included. This data was previously collected and included a category for nonbinary students.

The updated survey covers a recent school year. However, in place of the relevant numbers, a code is used. This code refers to a directive from the highest level of government.

Further details about the changes to the survey are available from the source. The missing data relates to a specific aspect of school life, and its removal has been noted in an analysis of the updated survey.
