The turn of the century was full of dynamic and multi-dimensional changes in the global economy. The most spectacular phenomena may include financial crises. They exerted influence not only on the economy, in which they appeared, but as a result of deepening of globalization, spread "infecting" others. The purpose of this article was an attempt to find similarities in the dynamics of changes in production and global demand that characterized the economy of the selected European Union countries. Information on the selected countries was gathered by analysis of statistical data. The starting point was to show the dynamics of gross domestic product (GDP) in selected countries and to find similarities between them. In the next section, attention was focused on the changes in the two components of aggre-gate demand: consumption and investment, particularly on their correlation with the rate of change of GDP. For analysis the economy of the European Union (represented by the euro zone) and the economy of Central and Eastern Europe were selected.
