6th explainer from the RSS’s climate change task force.

Royal Statistical Society @royalstatsoc.bsky.social

As heatwaves sweep across Europe, climate change is once again front and centre. But 10 years after the Paris Agreement, what do the numbers say? Both the modest improvements and significant challenges show the importance of stats in understanding climate progress. Read the latest CCTF explainer👇

Teaching economics or social sciences? Concepts like the unemployment rate or labor force participation can be tricky to explain clearly. Our new Work & Employment page breaks these down with clear explanations and visualizations — all free to download and use in your classes and presentations.

Being unemployed isn’t the same as not having a job — at least when it comes to labor statistics. The map shows unemployment rates around the world in 2025. Let’s see what this number captures — and what it doesn’t 🧵

Short days they may be, this time of year, but you get to see some lovely sun rises when walking the dog. Sun not quite up in Oxwich, Gower with the Bristol Channel in the distance.

Revisions not uncommon and all national statistical agencies are facing these challenges. Labour Force Survey in the UK is one problematic area that has had recent visibility. The US issue could be due to late surveys from small firms also.

Andy Garrett
@andygarrett.bsky.social

What remains clear is the national agencies need to be well funded as governments depend on a sound underling data infrastructure. If only some of the AI spare cash was directed to ensuring the core data infrastructure was sound and future proof.

Clearly some text has not aged well. Issues tend to be associated with countries where the data don’t fit the government’s narrative. That being said, employment data have historically come from surveys, not administrative data, and those surveys have become problematic with low response rates.
