Investment by sector, or gross fixed capital formation by sector, refers to the value of fixed assets acquired by institutional sectors for use in production.
It includes investment by households (primarily in dwellings and unincorporated enterprises), corporations (in machinery, buildings, and other fixed assets), and general government (in assets such as research and development, transport infrastructure, military systems, and public buildings including schools and hospitals). All OECD countries compile their data according to the 2008 System of National Accounts (SNA).
The indicator is measured as a percentage of total gross fixed capital formation.
