Unemployment rates typically are at their highest levels during the winter months. This is especially true of seasonally unadjusted local rates.
The BLS preliminary unemployment estimates for cities, counties and metro areas are based on Unemployment Insurance claims and a monthly survey of 1,450 Wisconsin households (0.06 percent), called the Local Area Unemployment Statistics (LAUS). Additional place of work data, available at the state metro levels only, is based on a monthly survey of approximately 5,500 Wisconsin employers (3.5 percent), called the Current Employment Statistics (CES). The CES data series is subject to significant revisions.
