In plain words
39.5% of seats
What it is. This measure is the share of seats in Tanzania's national parliament held by women, taken from Inter-Parliamentary Union records and passed on by the World Bank. It counts seats in the lower or single house at one point in the year, so it shows how many women sit in the chamber. It leaves out which roles they hold, such as committee chairs or ministerial posts, and how much influence they have over decisions.
Higher is better. A higher share means women hold more of the seats where laws and budgets are voted on, which brings the chamber closer to the make-up of the population. The latest figure, for 2025, is 39.5% of seats, up 2.1 percentage points from 37.4% of seats a year earlier. Since 2016 the share has ranged from a low of 36.6% of seats in 2016 to a high of 39.5% of seats in 2025. The current reading therefore sits at the top of its range for the period.
Why it matters. With women holding 39.5% of seats, they have a sizeable voice in votes on Tanzania's budgets, taxes and laws on family, health and land. Households gain when issues such as childcare, schooling and maternal health are raised by members who share those concerns. For the state, a chamber with this many women is better placed to claim wide public backing for its decisions.
