每月的就业和失业情况差别很大，从上个月观察到的变化主要是季节性的，而不是发展趋势。因此，将最新的统计数据与前一年同期进行比较。相比之下，经过季节和随机变化调整的趋势序列的数据具有相互可比性，因此从时间序列的趋势中更容易观察到与长期发展和周期性变化有关的现象。
Employment and unemployment vary quite considerably by month and the change from the observation of the previous month mainly describes the seasonal aspect rather than the trend in development. Thus, the latest statistical data are compared to the corresponding period of the year before. By contrast, the figures of the trend series that are adjusted for seasonal and random variation are mutually comparable and phenomena associatedwith long-term development and cyclical changes are thusmore easily observable from the trend of the time series.
