Portugal - Business Environment and Enterprise Performance Survey 2005

Sampling Procedure

The BEEPS 2005 sample was drawn from the universe of firms in a broad range of economic activities. In each country, the sectoral composition of the sample in terms of manufacturing (including agro-processing) versus services (including commerce) was determined by their relative contribution to GDP.

The sample included quotas related to size, ownership, export orientation, and geographical location to ensure sufficient numbers of firms to conduct analysis of firms with certain characteristics.
