Many, many people practice Taekwondo in a multitude of organizations, and independent schools around the world. The exact number would be unknown since records are not always kept, and the different organizations keep their own records which they do not share with each other.
According to the website for "world taekwondo history" in the related links below, you could say:
"Over 30 million people practice Taekwondo in more than 156 countries."
There is no way to accurately determine this number since the "sport" of Taekwondo is different than the "Martial Art" of Taekwondo. There might be as many as 30 Million people who study the art of Taekwondo, but a much smaller percentage of them are likely to be active in sport competitions.
Taekwondo is included in the Olympic games, and virtually every country around the world have representative organizations that train athletes. Each major Taekwondo Federation, and association host their own tournaments, State, and National Championships, and there are an unknown number of independent schools that hold their own competitions, so there is no official record that counts all of those together.
There is no single census for Martial Arts in the world. The estimate that I've seen is 50 million worldwide, over half in the United States.
There are tens of thousands of karate students in the US alone.

That would be none, as Karate is not an Olympic sport. Taekwondo is in the Olympics.
