Should emigration be included in the immigration debate?
This week in More or Less, we looked at the immigration debate and a critical factor to knowing who is coming and going across our borders that seems to have been overlooked in the debate about numbers.
What is it? Find out in the programme, but here is a clue: it involves following people on the ferry, wondering if you have lost them because they slipped into the shower and might now be wearing something different.
Follow us in the detective work of catching up with the thousands who enter and leave the UK, and it will all make sense.
Plus, the debate about UK productivity often compares our performance to that in the US.
It is often said that we fail to invest enough, fail to train or educate our workforce effectively and so lag behind others when it comes to the output per hour worked.
We take a different approach to the problem, comparing the economy sector by sector to see if some parts of the economy are more productive than others and whether that helps us identify the reasons why.
There is also a question whether the threat of violence or terrorism to the Iraqi elections can be quantified.
And in our series on averages, a short essay from Helen Joyce on the perils of averaging an average (yes, it does happen) and what that might have to do with explaining the pay difference between men and women.
More or Less was broadcast on Thursday, 27 January, 2005 at 1500GMT on BBC Radio 4.
