This document summarizes different types of data that can reveal gender dynamics in value chains, including quantitative data on sex segmentation, wages, and sales as well as qualitative data on access to resources, beliefs, and laws/policies. It provides examples of complementary data sources showing differences in participation, income, and returns for men and women in passion fruit farming groups in Kenya. The document also outlines an INGIA-VC process for integrating gender into value chain analysis using frameworks to assess gender dimensions, constraints, and strategies to support gender equity.
