Summary
Statistics Portugal releases the main results of the study “Well-Being Index for Portugal” carried out for the first time. The study was developed over the last three years, based on methodologies established by a group of international organisations, namely the OECD and Eurostat, and already applied by several national statistical offices. 
The design and the setting of all domains of the well-being index study benefited from the input of a group of renowned experts in the various fields used, to whom a sincere acknowledgment is more than due.
The index now published covers the period from 2004 to 2011 as well as preliminary results for 2012. The Index will be updated and published annually.
The well-being index increased between 2004 and 2011, and a slight slowdown in growth is estimated for 2012.
Out of the 10 domains used Education, Health, and Environment are the well-being components with the best performance during the period assessed.
Conversely, Labour and Earnings and Economic Vulnerability are the components with the worst performance.
The composite indexes Material Living Conditions and Quality of Life evolved in opposite directions, with the first showing a downward trend, accentuated from 2010 to 2012,  and the second showing a upward trend.
