Weekly Mediterranean crossings (Mediterranean example)

Description

A longer weekly count series of irregular sea crossings on the Mediterranean route, covering the ISO weeks 2015-W40 to 2025-W11 (494 weeks). The counts are larger in magnitude with fewer zeros than uk_weekly. The series is used in the irregular-migration application of Zens and Bijak (2026).

Usage

med_weekly

Format

A data frame with 494 rows and 3 variables:

week

ISO week label, e.g. "2015-W40".

count

Non-negative integer count of weekly crossings.

date

The Monday of the ISO week, as a Date.
