UK Migration

This dataset was created for a study examining whether the political salience of small-boat crossings in post-Brexit Britain corresponds to measurable institutional pressures or instead reflects symbolic politics. The main hypotheses proposed that small-boat arrivals would show weak or inconsistent relationships with welfare uptake and foreign-national prisoner counts, but a stronger association with hate crime, and that small-boat arrivals would remain a relatively small component of overall recorded migration compared with legal work and study routes.

The data bring together publicly available UK government statistics covering the years 2014 to 2025, with some indicators available for shorter periods. The dataset was compiled by merging annual data on population composition, migration routes, visa grants, refugee and humanitarian Universal Credit uptake, hate crime, and prison population indicators. Data were drawn from official government sources, including the Office for National Statistics, Home Office, Ministry of Justice, and Department for Work and Pensions. The dataset was structured at the annual level to allow comparison of trends and relationships across these domains.

Overall, the data suggest that fluctuations in small-boat arrivals were not clearly associated with welfare uptake or foreign-national prisoner counts, but were more strongly associated with reported hate crime. The dataset also shows that small-boat arrivals represented only a small share of total recorded migration, especially when compared with work and study visa routes. These findings suggest that small-boat crossings may function less as a major measurable source of institutional pressure and more as a symbolically powerful migration issue within public and political debate.

The data can be interpreted as aggregate annual indicators rather than evidence of individual-level behaviour or causation. They are most useful for examining broad temporal patterns, comparing migration-related indicators across institutional domains, and exploring how visible forms of irregular migration relate to wider debates about migration governance, hostility, and symbolic politics.
