Additional information about gender quotas

Inter-Parlamentary Union, (2021). "Women in Parliament in 2020 The Year in Review". 

A quota law for national elections was first introduced in 1997. According to this law, parties were required to include women on their lists of candidates, following the rule that every third candidate on the lists for Chamber of Deputies, and every fourth candidate for the Chamber of Senators, must be a woman. In 2010, the Electoral Law was amended to include the principle of parity, meaning that the number of men and women on the lists of candidates for any elections at the national and sub-national level should be equal (50/50), and that every other candidate on the lists should be a woman. The new law on parity has been applied for the first time in the recent 2014 general elections.

Although elections were planned for May 2020, they have been postponed due to CO-VID19

In 2020 “the share of women parliamentarians in Bolivia’s lower house dropped from 53.1 percent to 46.2 percent, a -6.9 point drop. This is the first time since 2014 that women’s representation has fallen below 50 per cent, but it remains close to parity. Bolivia has ranked second in the world for women’s representation in parliament since 2014, after Rwanda, and has parity quota in place”(Inter-Parlamentary Union 2021, p. 7).
