"Poland And The EU" (European Cover Story, May 10, 2004)

"Poland and the EU" (European Cover Story, May 10) said that Poland's per capita gross domestic product of $5,943 was 41% of the EU average, thus implying that the EU average was around $14,500 per capita. In fact, it is some $25,000. The discrepancy arose because the 41% was calculated using figures that had been adjusted for purchasing power parity.
