Question

How do you get word count to print at the end of a document in Pages?

Answer 1

Pages v5 does not provide a user assignable word count variable. With some AppleScript, and a paste operation from the clipboard, you can have locale punctuated word count in this format: 7,803 — anywhere in your document. The following AppleScript works with Pages '09 v4.3 through Pages v5.5.2 on Yosemite.
I would suggest that you copy paste the following AppleScript into your [Apple] Script Editor and save it (suggestion) wordcnt.applescript. Then, follow this with an option+Save As… and this time set the File format to Script Bundle, or Application with hidden extension — saved to your Desktop. Provided you have a Pages document open, you are then a double-click from the ability to paste your current word count into Pages.
Note: If you have Pages word count display enabled, it will automatically count your pasted value as another word which initially may deceive on true word count at the time the script was run.
AppleScript
--- copy below this line ---
property locale : "en_US.UTF-8" -- In Terminal, use the locale command to see yours
if not ApplicationIsRunning("Pages") then
     display dialog "Pages must be running to use this utility."
     return quit
end if
tell application "Pages"
    tell body text of front document
        set wordCnt to count words
        -- Don't want punctuated numbers? Remove the single quote from printf format
        set the clipboard to (do shell script "export LC_ALL=" & locale & "; printf \"%'d\" " & wordCnt)
    end tell
end tell
on ApplicationIsRunning(appName)
     tell application "System Events" to set appNameIsRunning to exists (processes where name is appName)
     return appNameIsRunning
end ApplicationIsRunning
