Moving annual total

Quarterly data can be converted to annual data by adding up the last four quarters. As a result, the data are adjusted for seasonal variation and recent quarterly data can be compared to annual data. For the second quarter of 2014, the quarterly data of the third and fourth quarter of 2013 plus the first and second quarter of 2014 are taken into account. The moving annual total for the fourth quarter is exactly the same as the figure for the entire calendar year.
