a Based on the number of paid hours.,,,,,,,,,,,,,,,,
"b The average weekly hours were assumed to be constant for these industries; therefore, the output per hour worked and the output per employee measures are identical in the years for which data are given for both measures.",,,,,,,,,,,,,,,,
c Data did not meet the publication standards for the Bureau of Labor Statistics and are considered less reliable than the published series.,,,,,,,,,,,,,,,,
"d Full-time and part-time employees are counted equally. Hence, these data do not reflect output per full-time equivalent employee.",,,,,,,,,,,,,,,,
