Legislature directly elected

Question: To what extent is the legislature directly or indirectly elected?
Clarification: If the legislature is unicameral, v2xex_elecleg is measured as the proportion of legislators directly elected + half of the proportion that are indirectly elected. If the legislature is bicameral and the upper house is involved in the appointment of the chief executive, the same proportion of directly and half of the indirectly elected legislators is calculated for the upper house; the scores for the lower and upper houses are then averaged. Note that a popular election is minimally defined and also includes sham elections with limited suffrage and no competition. 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. Since the variables coding the share of directly and indirectly elected legislators are not yet fully in sync for all country dates, a few observations now receive an index value larger than 1.
