seasonal unemployment

Some jobs simply don't exist all year round. A ski resort needs lift operators in winter but not in summer. A beach town's ice-cream sellers and lifeguards work in July, not January. Farm workers are needed at harvest, then let go. Every year, like clockwork, these workers lose their jobs at the same predictable time — not because the economy is sick, but because the calendar turned. That regular, calendar-driven joblessness is seasonal unemployment.

Seasonal unemployment is the unemployment that recurs at the same times each year because demand for certain kinds of work rises and falls with the seasons. It is utterly predictable: tourism peaks and troughs, agricultural planting and harvesting, retail surging before holidays then slumping after. Because it is so regular, statisticians can mathematically remove its predictable pattern from the data — a process called seasonal adjustment — so that the published unemployment figures reflect genuine changes in the economy rather than the fact that, say, retail always sheds workers in January after the holiday rush.

Seasonal unemployment matters mostly because it must be filtered out before we can read the other, more meaningful types. If you saw raw, unadjusted data showing unemployment jumping every January, you might wrongly think a recession had begun, when really it is just the usual post-holiday layoffs. For the workers affected, it is real and recurring — many in tourism or farming string together seasonal jobs across the year — but for diagnosing the economy as a whole, the goal is usually to look past it to the underlying trend.
