For example, the ratio of defence and economic affairs to total government expenditure has been decreasing, while the share of health has been increasing rapidly (Figure 6.5). As Figure 6.6 shows, the central government controls only 40% of the overall budget. The remaining 60% of the total budget is controlled by local governments and the education authority. This is in contrast to the situation in other OECD countries, implying that Korea is one of the most decentralised OECD countries.
