WARSAW, Poland (AP) â¿¿ Official figures show Poland's unemployment rate rose to 14.2 percent in January from 13.4 percent in the previous month. The figure, released Monday by the Central Statistical Office, comes as the country is seeing a slowdown in its once-strong economy. Some job losses, however, are also typical in winter, when work in agriculture and construction declines due to cold weather. Other data released Monday gave a more positive signal about the economy, showing that retail sales rose by 3.1 percent year-on-year in January. The head of the central bank, Marek Belka, was quoted in the Polish media as saying that could be a sign the economy is rebounding. Poland's economy grew 2 percent last year and economists expect slightly weaker growth this year.
