A good month for retail sales
From February to March 2007, the seasonally adjusted index of retail sales rose by 1.1 1 per cent.
Seasonally adjusted index of volume corrected down by 0.2 per cent. More here .
Due to Easter, the sales index for March is difficult to compare with the corresponding month in 2006. The seasonally-adjusted index takes Easter into account, but it is difficult to correct for Easter shopping. Therefore, the seasonally-adjusted index for March is more uncertain than the seasonally-adjusted indices for the other months.

Changes in calculations
From the publishing of the Index of retail trade for March 2007, there will be used a new and improved method for pre-adjustments of Easter effects. By the old method, we assumed that the Easter effect lasted for three weeks, at the same time as all the different industries where pre-adjusted equally. The result was that the Easter effect sometimes could be overestimated. By the new method, the number of days that are being pre-adjusted will depend on when the Easter is. Each industry will be pre-adjusted individually. One example is that the effect of the Easter is larger for retail sales which contain everyday commodities, than for retail sales with shoes, clothes and furniture.
The new method will, unlike the old method, also pre-adjust for Ascension Day and Whit Monday. All retail trade time series that are seasonally or working day adjusted, are recalculated back to 1979.
