The pie charts illustrate the percentages of money spent on four categories of music in three selected years: 2005, 2008 and 2011 in Northern Ireland.
Overall, the spending on four categories was distributed unevenly. Additionally, the amount of money spent on CDs and concerts followed a downward trend, while a reverse pattern could be seen in the figure for Digital downloads. Meanwhile, other sources remained relatively stable during this time.
In 2005, the expenditure on CDs was the leading category, constituting over half of the total, followed by Concerts, at 31%. Next came digital downloads with 6%, while Other sources recorded the lowest proportion, at only 2%. By 2008, the spending on CDs dropped steeply to 41%, but still maintained its top position. Concerts slipped to 23%, as opposed to Digital music which more than quadrupled its figure to a quarter. The amount of money spent on other sources remained unchanged at this point.
By 2011, the expenditure on CDs decreased dramatically to 26%, losing its leading position to Digital downloads, at 43%. Concerts rose slightly to 28%, ranking second in the final year, while Other sources climbed marginally, settling at 3%.
