The data covers small boat arrivals across the English Channel, irregular migration trends, asylum claims and initial decisions, grants of protection, asylum seeker support and accommodation, processing costs, and the asylum decision backlog. All figures are updated automatically when new data is released, so the numbers you see here always reflect the latest available quarter or financial year. The site is designed to make it easier to understand how these figures have changed over time and how they compare across different categories.
