And then another graphics that also didn't make it. Here's a joyplot for UK residents in Australia. Definitely a cohort effect going on with Australia as people age and you can see the sharp increase in young people. ENDS

We can also look at the data from Spain. The population of UK-born residents is much older than the Spanish population. More British people aged 65 and over are now leaving than arriving to live in Spain

The British population in Spain is far older than the country’s average

This didn't make the article but even more interesting is that we can look at the Australia Department of Home Affairs to look at the occupations they grant visas too. Here's the top 8 occupations with GPs and medical officers the number one. Source: www.homeaffairs.gov.au/research-and...

The Australia Bureau of Statistics captures how many British migrants arrive in and leave from Australia

Net migration of Brits to Australia is climbing, with more people arriving than leaving

But we also compared our numbers to what other countries and organisations are saying. The UN compiles numbers counting the number of UK born citizens in different countries. Australia comes out on top

English-speaking or European countries are home to the most British people living abroad

For the first time we've been able to look at the age breakdown of British migrants. The gap between those leaving and arriving has grown fastest for 25- to 34-year-olds.

Today we published an explainer looking at ONS numbers on British migrants; what we know and what we don't know. www.ons.gov.uk/peoplepopula...

Emigration of British nationals has been broadly stable recently - but remains lower than in September 2021

Estimated migration levels to and from the UK are higher after applying improved methods
