National Statistical, the blog from the UK’s Office of National Statistics.
You can read it here.
This blog has really interesting articles focusing on particular datasets, such as this one about happiness levels in the UK, which covers implications for policy, as well as an interesting correlation between the gap in happiness levels and the results in the Brexit referendum.
The posts are not too long and, overall, they are very, very digestible.
I find this blog a great way of keeping in touch with ONS report releases, and of understanding the numbers behind the media headlines. It is also a great source of interesting insights, and even inspiration for blog posts.
One limitation: it covers UK data, only.
