If its GDP growth persists, Kazakhstan is likely to qualify as high income economy in the foreseeable future (Figure 5.2). In 2011 the total public budget amounted to USD PPP 23.1 billion (current prices), an increase of 56% compared to 2005 (World Bank, WDI). This represents, however, a relatively modest share of national income. In 2011, general government total expenditure equalled only 22% of GDP, below relative government spending in economies with comparable per capita income (emerging economies: 30%), historical legacy (Central Asian region: 28%), and also the average for OECD countries (43%) (Figure 5.3).
