This data gives population and migration estimates for children aged two to three years between 2019 and 2024, using the 2024 population and migration estimates. The 2024 estimates were provisional and will be revised in the 2025 report (published in September 2026). Migration figures are 12-month rolling totals produced at three-monthly intervals. Figures for 2017 and 2018 are currently under quality assurance review and so are not included.
