The study aims to investigate the share of MSMES in the global level among the developed, developing and least developing countries. The studies further examined based on Micro and Small Enterprises (MSEs) and Non-Micro and Small Enterprises (Non-MSEs) and their contribution towards GDP in global countries. The finding of the study revealed that most developed and developing countries have highest numbers of micro enterprises which shows that most of developed and developing are focusing on micro enterprises. There are 26 percent of MSMEs worldwide are formal and the remaining 74 percentage are informal (non-registered) firms. This study suggests that Non-MSEs forms of business is risky for economic development in worldwide countries. Therefore global countries should take necessary measures to regulate formal MSEs with feasible policies for economic development of the country.
