I recently used twitters trends using the following for running some basic analytics
which Returned the top 50 trending topics for a specific WOEID. I used the “world” and “USA” just for testing and noticed that for the top 50 trends in the response the following occurred.
* for USA only 14 tweet_volumes had data and the rest 36 were Null
* for WORLD only 31 tweet_volumes had data and the rest 19 were Null
Why are tweet volumes not present for all the trends ? Is this common ?
