ENAPROCE 2015 is the first large-scale firm survey in Mexico. It is statistically representative at the state and sector levels and compares with US MOPS. It includes information for 25,456 firms from manufacturing, commerce, and services, with a different questionnaire applied to 9,103 microenterprises. The survey was implemented by INEGI (national statistics office), guaranteeing a very low non-response rate (4%). The sample framework is the 2014 Economic Census, which allows matching information with other National high quality statistical projects.
