By working with parliamentarians, UNFPA brings attention to, and understanding of, the need for using high quality population data. In Afghanistan, where the first crucial steps have been taken to collect and analyse reliable data, this need is especially acute.

UNFPA runs an innovative programme of advocacy and dialogue to ensure that parliamentarians are aware of the need for good population data, and are able to use it effectively. By 2014, 108 planners and policymakers had been trained to use data for planning.

UNFPA also provides parliamentarians with training on gender issues, legislation and drafting laws. By arranging trips to other parliaments and parliamentary forums, such as the annual Inter-Parliamentarian Union in Geneva, UNFPA helps to build exposure and shared lessons on how to conduct the business of government.

A sub-set of UNFPA's work with the parliament concentrates specifically on women parliamentarians. Although they comprise 27 percent of parliamentarians, exceeding the global average, women's voices have historically been drowned out by their male colleagues. With UNFPA advocacy and capacity building, women parliamentarians have formed a separate caucus to express their opinions and use their votes without fear.
