earnings of the entire U.S. population by decade of age as reported in tables PINC‐01, PINC‐04, and PINC‐05 of Current Population Survey (U.S. Census Bureau, 2015). On the other hand, based on the background document (Lawrence et al., 2014), the CDC apparently used weekly income by category (US Census Bureau, 2015). Therefore, the CDC Cost of Injury Reports (CDC, 2015b) could not generate an objective estimate of the mean of the top category and the imputed mean appears to have been truncated (T. Miller, personal communication, Oct. 14, 2011). This effect was partially offset, however, by separate imputed values for household production such as cooking, cleaning, and child care, in the CDC estimates (CDC, 2015b), contributing to its higher values for persons aged 65 and above.
