The Inquérito às despesas das famílias 2005/2006 (IDEF 2005/2006) was carried out by Statistics Portugal between October 2005 and October 2006, with the aim of estimating indicators on income distribution and on the level and structure of expenditures of the private households residing in Portugal, and about its well-being indicators. It corresponds to the most recent edition of the every five year series of surveys on household budgets initiated in the 60’s.

Statistical information presented in this publication reflects five different perspectives on the private households residing in Portugal: distribution of the number of private households; average annual expenditure by private household; average income by private household; adult equivalent income, poverty and inequality; and a few well-being indicators.
The five perspectives are analysed according to the territorial distribution by NUTS II regions of 2002: Norte, Centro, Lisboa, Alentejo, Algarve, Região Autónoma dos Açores, Região Autónoma da Madeira.
