​In 2014, the editing procedures used to evaluate data consistency and allocate missing values for occupation, industry, and class of worker data were modernized. Improvements include updates to data consistency and allocation rules to accurately reflect occupation, industry, and class of worker requirements, the retention of more as-reported data, and improved educational attainment restrictions.

The improvements to these procedures contributed to changes in some occupational categories including managers, buyers and purchasers, scientists and science technicians, physician assistants, licensed practical and licensed vocational nurses, nursing, psychiatric, and home health aides, supervisors of gaming and personal service workers, file clerks, mining machine operators, and automotive and watercraft service attendants. Industries affected include other health care services and home health care services.
