New Migration Briefing – East Sussex in Figures

A new briefing analysing the latest data on migration into and from the county is now available .

This analysis looks at a variety of different data sources, to give a broad picture of migration into and out of the county.

Key points from the briefing:

In 2023, internal migration continued to be the main driver of population growth in East Sussex, with international migration representing a slightly smaller proportion of population change.

However, while the number of net arrivals from within the UK (internal migration) was around the average for the last 10 years, at 4,495 in 2023 (10-year average 4,557), international net arrivals were at their highest ever level with 2,923 net arrivals in 2023 (10 year average 466).

With more deaths than births occurring in the county every year for over 40 years, and negative natural change at its highest ever level, the rising natural decline of the population is offset by gains from new residents moving in.
