Readers Question: It is unclear what Seasonally adjusted means?
Seasonally adjusted figures take into account seasonal factors in time series.
Unemployment will have seasonal patterns. For example, over the summer holidays extra jobs are likely to be created and unemployment will typically fall. In winter, unemployment may rise as less tourist jobs are available. (apart from a few weeks over Christmas).
Therefore, seasonally adjusted figures take away these usual seasonal changes in unemployment to give a better guide to the underlying statistic.
At the height of the summer, the actual unemployment figure will be quite low. But, the seasonally adjusted figure will be higher because it takes into account this seasonal fall in unemployment.
Example
For example, unemployment figures for the month of June may show a fall of 10,000 to 7%. However, statisticians may know that on average unemployment falls 100,000 in the month of June because it is the start of the summer holidays (more jobs created). Therefore, the seasonally adjusted figure for June will show a higher unemployment rate than the actual figure.
