This chartbook presents information on the extent and nature of unemployment in the United States. The statistics presented are part of a broad array of unemployment and related labor force data available from the Current Population Survey, a sample survey of some 60,000 households conducted monthly by the Bureau of the Census. The 28 charts and graphs in the booklet are organized into two parts. The charts in part 1 focus on the extent and nature of unemployment and the characteristics of jobless workers, while the charts in part 2 illustrate the sensitivity of unemployment and related measures to changing economic conditions. Beside each chart, highlights are presented in narrative form. An appendix to the chartbook explains the methods used to prepare the data and includes definitions of the important concepts used in the booklet. A list of selected references completes the chartbook. (KC)
