10. Central tendency and distribution shapeThe Bureau of Labor Statistics (BLS) is the main fact-finding agency of the US government in the fields of labor economics and statistics. Data from the Current Population Survey (CPS), conducted by the BLS and the Census Bureau, have been used to indicate a downward trend in retirement age. [Source: Gendell, M. (October 2001). Retirement age declines again in the 1990s. Monthly Labor Review, 124(10), 12–21.]The following DataView tool displays a hypothetical data set consisting of annual income (as measured in thousands of dollars) and age of retirement for 100 retirees.
