How our spending habits have changed
Irish people are spending just 4.9pc of their money on alcohol and cigarettes compared to 7.5pc a decade ago, the CSO figures show.
Spending on food, meals out, hotels and recreation have slipped dramatically as a proportion of total household spending.
By contrast housing, utilities, transport, health and communications spending all soared between 2001 and 2011.
The CSO adjusts the importance given to the price of different goods and services every five years in line with spending.
The price of package holidays has become increasingly irrelevant but airfares more so as we snapped up more flights.
