The gender pay gap is a stubborn feature of almost every labour market, and Sao Tome and Principe is no exception. Male contract associate engineers in Sao Tome and Principe earn an average of 72,840,900 STN a year, while female contract associate engineers earn around 65,280,600 STN.

A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.
