From Paul Broady
In the discussion of the “number of people living on less than $1 per day” (20 October, p 14, and Letters, 10 November, p 26), is this $1 adjusted for changes in its purchasing power? This never seems to be stated.
• It is adjusted: in the article we noted that the figure was $1.08 in 2004 dollars.
