Real average weekly earnings rose by 0.5 percent from May to June after seasonal adjustment, according to preliminary data released by the Bureau of Labor Statistics of the U.S. Department of Labor.

Increases of 0.3 percent in both average weekly hours and average hourly earnings were partially offset by a 0.1 percent increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).

Data on average weekly earnings are collected from the payroll reports of private nonfarm establishments. Earnings of both full-time and part-time workers holding production or nonsupervisory jobs are included. Real average weekly earnings are calculated by adjusting earnings in current dollars for changes in the CPI-W.

Average weekly earnings rose by 3.9 percent, seasonally adjusted, from June 2006 to June 2007. After deflation by the CPI-W, average weekly earnings increased by 1.3 percent. Before adjustment for seasonal change and inflation, average weekly earnings were $587.86 in June 2007, compared with $565.42 a year earlier.
