In Australia we are obsessed with one month changes in our unemployment figures. They are generally about plus or minus 0.1 percentage point. Unfortunately the 95% CI on changes is plus or minus 0.2, so just noise. Every now and then a journalist who actually understands will write an article explaining that it is all pointless, but nothing seems to change.

I'm also surprised by how often people will confuse millions and billions, especially when it is an odd context. So a company will be described as losing $60 billion a month, when it should be $60 million, because nobody can do the math and work out that $60 billion per month is more like the US federal deficit
