Subnational governments are key investors that account for almost 60% of total public investment.
In most OECD countries, subnational governments (SNGs) have a key role in public investment. In 2016, they carried out near 57% of public investment in the OECD area. This ratio tends to be higher in federal countries (70% on average for the nine OECD federal countries) than in unitary countries (51% on average for the 26 unitary countries). Combining investments by the federated states and by local governments, subnational investment exceeds 70% of public investment in Australia and Mexico, and more than 85% in Canada and Belgium. At the other end of the spectrum, the role of subnational government in public investment is particularly low in Greece, Ireland and especially Chile, where the local share is 13% ( 5.11).
