Definitions of parameters and data sources
| Indicator name | Definition | Year | Source |
| GDP per capita, current prices (US$) | GDP is expressed in current US$ per person. Data are derived by first converting GDP in national currency to US$ and dividing it by the total population | 2010–2018 and projections up to 2026 | IMF |
| GGHE (% GGE) | GGE includes consolidated direct outlays and indirect outlays (eg, subsidies to producers and transfers to households), including the capital of all levels of government, social security institutions, autonomous bodies and other extra-budgetary funds. GGE on health comprises the direct outlays earmarked for the enhancement of the health status of the population and/or the distribution of medical care goods and services among the population by the following financing agents: central/federal, state/provincial/regional and local/municipal authorities; extra-budgetary agencies and social security schemes; and parastatals. All can be financed through domestic funds or external resources | 2010–2019 | WHO: Global Health Expenditure Database |
| General Government Expenditure (% GDP) | GGE includes consolidated direct outlays and indirect outlays, such as subsidies and transfers, including capital, of all levels of government social security institutions, autonomous bodies and other extra-budgetary funds | 2010–2019 | WHO: Global Health Expenditure Database |
| Current expenditure on health as % of GDP | This indicates the level of health system expenditure within a country relative to the output of the whole country. It shows the importance of the health sector in the economy. Also, it indicates the societal priority of health since the indicator provides information on the level of resources channelled to health relative to other uses in the overall economy | 2010–2018 | WHO: Global Health Expenditure Database |
| GGHE as % GGE | Expressing domestic GGHEs as a share of the GGE is essential to compare the size of current public health expenditures relative to the total size of government expenditure | 2010–2018 | WHO: Global Health Expenditure Database |
