Dataset:Provisional Long-Term International Migration estimates
22 August 2019
Preliminary adjustments have been made to the headline measures of migration presented in the Migration Statistics Quarterly Report (MSQR). The adjusted estimates are not available in this dataset so it will not match those in the MSQR.
The adjusted estimates are available in the data downloads for the charts in the MSQR. This dataset will be updated to include the adjustments on 12 September 2019. As other new data sources become available, we will continue to refine our adjustments further and reflect this in our migration statistics in future.
This spreadsheet is updated quarterly. The spreadsheet always contains data for 40 rolling years. Each new release removes the oldest data and adds the latest available data. In addition, previously published estimates may be revised for the following reasons:
Estimates based upon provisional data are revised when final data becomes available
Revisions may also be made when methods or systems are improved
These types of planned revisions should not be confused with errors in released statistics, which are genuine mistakes. Such mistakes occur rarely and, when they do happen, corrections are made in a timely manner, announced and clearly explained to users in line with the Code of Practice for Statistics (Quality pillar, practice Q3.4).
