Notas:
In 2011 the coverage of the energy sector (CNAE 35) is improved and widened incuding in the framework companies not previously included.
 In 2013 the survey widens its population and territorial scope, extending its coverage to companies without wage earners and including the companies of Ceuta and Melilla. Moreover, the coverage of the waste management sector is improved (CNAE 38).

As a consequence of this incorporations, the evolution reflected by the economic variables in relation to previous years is based not only on possible real changes produced in that period but also on the increase derived from the said updates of the population target of study.
