What is seasonal adjustment?
Most economic series, including employment and unemployment data, are affected by seasonal variations. Often it is difficult to tell from raw statistics whether developments between any two months reflect changing economic conditions or merely normal seasonal fluctuations. So, to compare employment and unemployment data for any pair of months accurately, a statistical technique known as seasonal adjustment is used.
