Numbers like this are really confusing. Ok there is an year on year decline of 7%. But how does that compare to previous years? Did they grow dramatically and now they are losing some steam? Or has it been declining for the last few years? One of the biggest losers is supposed to be healthcare(20%). Is that because they had a huge spurt because of the pandemic and now there is a reduction? I am not sure what the other industries are so I am not sure what to make of it.
