The share of LTC spending in total health spending or as a share of GDP has gradually increased over the last 15 years in many OECD countries as demand for care grows with population ageing and the extension of publicly financed services.
In some countries, spending on LTC has not grown much faster than the economy as a whole. In Slovenia and Spain, for example, the shares of LTC relative to GDP in 2018 were only 0.1-0.2 percentage points above those in 2005, at 1.2% and 0.9% of GDP, respectively.
In Spain, the share of LTC spending has been stagnating since 2009, with LTC spending tracking GDP growth.
Nothing to add.
PS. You'll not find such data in the spanish press. Somebody cares about it.
