Compiled with the goal of looking beyond the national domestic level into individual party-level explanations for women's political leadership. Consists of 2 parts which analyze the party level for women's ascendancy to political leadership. Part 1 focuses on an aggregate of 25 non-randomly selected countries, Part 2 focuses on Lebanon. The study records the level of religiosity of political parties, where it refers to religious components in the party's political platforms or the extent to which religion penetrates a party's political agendas. Both datasets examine party variation in religiosity, party structure, respondents' station within a parties' decision-making inner structures, and other party-level characteristics that may impact women's leadership in various political parties. Additional variables include identifiers for Muslim, Arab, and European states, level of secularism, election design, party design, and age of party.
