The pension system will be discussed in detail in the next chapter, but the system is fairly comprehensive with public spending at around 5.2% of GDP in 2007 (it was 6.6% in 2009, Chapter 4), about 2 percentage points of GDP below the OECD average. The amount spent on cash transfers to the working-age population and their children is much smaller: just below 2% of GDP. Public expenditure on health amounted to 3.5% of GDP in 2007 (OECD, 201 lb), well below the OECD average of around 6% of GDP. Public spending on other social services amounted to almost 1.5% of GDP in 2007, of which about 40% concerned public spending on childcare and kindergartens (Sinjavskaya, 2010).
