What do you do in situations where female parliamentary representation is zero?
Only 4 out of 159 countries included in the GII has female shares of parliamentary seats equal to zero. Because the functional form is multiplicative, we replaced the zero value with 0.1 percent to make the computation possible. The rationale is that while women may not be represented in parliament, they do have some political influence. The relative rank of the country is sensitive to the choice of the replacement value. The lowest observed non-zero female shares of parliamentary representation was 0.5% for Yemen.
