What does lagged mean?
Lagged means delayed, behind, or slower than expected or than something else. It is especially common in business, economics, technology, and formal reporting, where “lagged growth” describes expansion that trails the wider economy and “lagged behind” identifies a failure to match another person, organization, or target. The word can also function as the past tense and past participle of “lag,” as in “The project lagged behind schedule.” In economic and statistical usage, a lagged value is one that refers to an earlier period or reflects a delayed response to another variable. Although “lagged” can suggest an undesirable lack of speed, it is not always negative: in a historical comparison, it simply identifies the earlier member of a sequence. Its clear association with delay makes it useful for describing results, developments, or responses that trail their expected timing or benchmark.
Delayed in time or development; behind a comparable level, standard, or schedule.
"The figures show lagged recovery in employment after the downturn."
Particularly frequent in economic, business, and technical descriptions.
The past tense and past participle of “lag,” meaning to move or develop more slowly than another person or thing, or more slowly than expected.
"Small firms lagged large firms in adopting the new system."
The form is transitive or intransitive: it can be followed by “behind” or a direct object identifying what was trailed.
In economics, “lagged” also describes a figure based on an earlier period, turning the idea of falling behind into a way of examining what happened before.
