My company has been tracking the mood and emotions of Irish adults every month since April 2009 - six years ago this month. The latest Economic Recovery Index report is out:
The information on reported happiness, sadness etc shows an obvious correlation with general economic sentiment, though our emotional state appears to have a strong seasonal influence as well. They're also vulnerable to the occasional shock too, of course, such as when the IMF came calling at the end of 2010.
Still, good to see things improving - albeit the Index goes from 0 to 100 and we're still only at 40...
The historical data set covering April 2009 to April 2015 is here fyi.
