Other Indicators of the Political Transparency component
De Facto Lobby Transparency Index
This indicator is the sum of scores granted in the de facto lobby transparency subindicators. It captures how much information on lobbying contacts is actually published and accessible in practice. The score is expressed as a percentage of the maximum possible lobby transparency score (its level of fulfilment of all relevant criteria).
De Facto Political Finance Transparency Index
This indicator measures a country’s de facto political finance transparency, i.e. how transparently the rules are applied and enforced in practice. Each country’s score is expressed as a percentage of the maximum possible score in political finance transparency (its level of fulfilment of all relevant criteria in practice).
De Jure Lobby Transparency Index
This indicator reflects the extent and strength of legal provisions requiring disclosure of information on lobbying contacts. The score is binary and indicates whether there is a law mandating a lobbying register.
De Jure Political Finance Transparency Index
This indicator measures a country’s de jure political finance transparency, i.e. the strength and scope of its legal framework. Each country’s score is expressed as a percentage of the maximum possible score in political finance transparency (its level of fulfilment of all relevant criteria).
Lobby Transparency Index
This indicator measures the overall transparency of lobbying in a country. The Lobby Transparency Index aggregates seven subindicators—one de jure and six de facto—that assess the online availability of information on contacts between decision-makers and lobbyists. Each country’s total score is expressed as a percentage of the maximum possible lobby transparency score (its level of fulfilment of all relevant criteria).
Political Transparency (T-Index)
A composite indicator derived from the T-Index assessing the availability of financial disclosures and conflict of interest disclosures of public officials
