Experts in petroleum products made slightly over 60 billons dollars in 2015 and those in engineered goods made more than 55 billion dollars in the same year. Furthermore, both of them recorded increased number in the next year. Professionals in gems and jewellery made more income than those in agricultural products and those in textiles in the both years. However, they are the only people in the category which has reduced record change in values from 2015 to 2016. People working in agricultural products made profit steadily with the number of around 32 billing dollars.
