The long-term tendencies, observed in the process of national income's trending were shown. Instead of the concept of income the authors use also the term product, which is currently applied as the measure of economic activity by international organizations such as IMF, World Bank, WTO or OECD. The publication covers the second half of the XX century. The data comes mainly from Angus Maddison research publications and statistical yearbooks and the figures and tables show the size, dynamics and division of the world product between particular regions and states. The authors emphasised the changes, which were observed in the income's distribution and focused on the correlation between the dynamics of GDP and the increase in the area's significance for the world's economy. .
