Gender and development are among the two most important components of any economy to sustain its perpetual and sustainable economic growth in both the long as well as short run. The role of women in parliament and the interrelationship between gender and development is critically analysed. Women’s representation in parliament is the dependent variable and the predictor variables considered are gender development index, female access to assets, female labour force, and country GDP per capita. Data were collected from the UNDP human development report for the period 2015 to 2021–2022 and World Bank for 188 countries of which finally 159 were considered to develop the model based on data availability. We have used the theoretical lens of social stratification theory and gender role theory to frame the hypothesis. A random effects model-based panel regression analysis of the data indicated a strong positive relationship between gender development index and the dependent variable, but no relationship between female labour force, and access to assets. The study addresses a critical gap in policy and development of the literature on gender, politics, and development using a global data set, establishing the importance of indicators such as gender development index, and laying down the path for future research on the subject.
