Elected officials index

Question: Is the chief executive and legislature appointed through popular elections?
Clarification: This index attempts to measure (a) whether the chief executive is elected, either directly elected through popular elections or indirectly through a popularly elected legislature that then appoints the chief executive; and (b) whether the legislature, in presidential systems with a directly elected president that is also chief executive, is directly or indirectly elected. Note that a popular election is minimally defined and also includes sham elections with limited suffrage and no competition. Similarly, "appointment" by legislature only implies selection and/or approval, not the power to dismiss. This index is useful primarily for aggregating higher-order indices and should not necessarily be interpreted as an important element of democracy in its own right.
Scale: Interval.
