A Checkpoint: Two Lenses, Two Kinds of Evidence

The subject remains the same: whether workers with bachelor’s degrees are well matched to the occupations where they work. What changes here is the evidence used to judge that relationship. By putting the BLS entry assignment beside the observed education of workers, we can make a useful distinction: a disagreement between estimates may reveal different questions being asked, not a simple mistake in arithmetic.

The same graduate, seen through two questions

Imagine a worker with a bachelor’s degree employed in an occupation that BLS assigns an entry requirement below the bachelor’s level. The worker and the job are fixed. Under the BLS lens, the comparison is between the worker’s degree and the occupation’s typical path into the occupation. Because the assigned path is lower, the worker is counted as underemployed under the BLS-based approach.

That classification answers a specific question: is the worker’s education above what is typically needed to enter this occupation? It is useful when the concern is access to occupations and the education level commonly associated with entry. It is less suited to the question of what the worker actually does after being hired. The occupation can include senior, specialized, or regionally distinct roles, and the entry assignment does not distinguish among them.

Now consider the same worker through a realized-matches lens. The relevant evidence is the education distribution of people currently employed in the occupation. If workers with bachelor’s degrees or higher are the largest group, the plurality version treats the occupation as bachelor’s-degree level. If they are more than half of workers, the stricter majority version does so. The worker may therefore be outside the underemployment group under a realized-match rule even though the BLS entry assignment remains below bachelor’s level.

This second classification answers a different question: what education has the labor market actually placed in this occupation? It can reflect employer preferences and changes in the work more directly than a fixed entry category. But it still does not observe the worker’s tasks. A graduate-heavy occupation may contain degree-level roles, or it may have adopted a degree as a screening signal without changing the underlying work. The observed distribution is evidence about the workforce, not a transcript of every job.

The distinction can be stated plainly:

  • The BLS lens compares a worker’s education with the typical education needed to enter the occupation.
  • The realized-matches lens compares the occupation’s worker distribution with a threshold for what counts as typical.

Neither comparison is a complete test of whether a person’s capabilities are being used. The first can overstate mismatch by treating a broad entry category as the whole occupation. The second can understate mismatch by treating current hiring as proof that the work requires the credentials employers have selected.
