The April 14 article “Window on a great divide” ended with the commentary that the average salaries of $26,470 and $26,550 for workers in sporting goods and office supply stores, respectively, “fall short of the median household income in the U.S. in 2010, which was $49,455.” This was misleading, since dividing this amount by 1.95, the mean number of adult residents in a household in 2010, according to the Census Bureau, produces an average salary per adult of $25,361, somewhat lower than the averages cited. I urge the editors to be extra careful about consistency when comparing such figures and drawing conclusions.
