No, appendices are not included in the word count. Only words that are in the main body of your paper count toward the final word count, including information from tables, quotes, lists, and citations. Seeing as appendices are included after the paper itself, along with footnotes and references, they should not be included in the word count. Also, the summarized appendix data is already present in the body of the text, whereas the appendix contains all the raw data.
