Different sources will quote different numbers of objects.
The reason is that there were millions of debris particles. So you find counts of different sizes.
I got 10% by comparing the number in the Wikipedia article over a certain size with the number of objects that NASA is actively tracking. If NASA is actively tracking at a different size threshold, that would explain the discrepancy.
Regardless of the exact numbers, this Chinese test is clearly a significant part of the problem by itself. And the altitude chosen means that it will continue to be a problem for a very, very long time.
