Headcount measures have been criticized as potentially inadequate when looking at changes in poverty or literacy over time or in determining the success of particular public policies. In this paper I argue that using the headcount measure of unemployment can be misleading as well. I utilize an externality argument similar to the one used in the literacy debate and provide a class of measures that capture externalities of employment.
