[Excerpt] This report presents earnings data from the Current Population Survey (CPS), a national monthly survey of approximately 60,000 households conducted by the U.S. Census Bureau for the U.S. Bureau of Labor Statistics (BLS). Information on earnings is collected from onefourth of the CPS sample each month. It is important to note that the comparisons of earnings in this report are on a broad level and do not control for many factors that can be significant in explaining earnings differences. See the accompanying technical notes section for more information, including a description of the source of the data and an explanation of the concepts and definitions used in this report.
