The IPS estimates provide further detail than is available from LTIM. However, where LTIM figures are available, they are considered to provide a more complete estimate of migration. Provisional figures allow for a timely comparison of recent migration patterns on a quarterly basis. However, these are subject to change. The final LTIM estimates are considered to provide a more reliable picture of migration and allow for annual comparisons over time.
Patterns of long-term immigration and emigration differ due to a number of factors that affect particular nationalities including: visa requirements, economic factors and government policies. For example, different visa restrictions apply to different nationalities. The latest visa restrictions affect those citizens outside the EU applying to work in the UK. Any analysis of migration patterns needs to consider these factors when identifying and explaining key messages. Further guidance on comparing different data sources can be found in the MSQR User Information.

This refers specifically to the passport being used to enter / leave the UK at the time of interview. It does not refer to any other passport(s) which migrants of multiple citizenship may hold. More generally a British citizen is someone with citizenship usually through a connection with the UK: birth, adoption, descent, registration, or naturalisation. British citizens have the right of abode in the UK.

Confidence interval This is the range within which the true value of a population parameter lies with known probability. For example the 95 per cent confidence interval represents the range in which there are 19 chances out of 20 that the true figure would fall (had all migrants been surveyed). The uppermost and lowermost values of the confidence interval are termed ‘confidence limits’.
