Taken as a percentage of GDP, total public sector outlays shows the proportion of total annual expenditure by all levels of government compared with the expenditure of the economy as a whole. Total public sector outlays as a percentage of GDP increased steadily in the second half of the twentieth century and have been at around 40% since the 1980s.
