How biotechnology lead data manager pay ranges in Sierra Leone
A good way to think about salary in Sierra Leone is to look at the distribution rather than the headline average. Half of all biotechnology lead data managers in Sierra Leone earn less than 68,398,200 SLL a year, and the other half earn more. That middle number is the median, and it is usually more useful than the average for answering "is my pay normal here".

The middle 50% of biotechnology lead data managers sit somewhere inside that band, which is where the typical reader of this page probably lives.
The very lowest reported salaries sit around 32,879,500 SLL. The highest stretch to 104,639,900 SLL, though only a small fraction of earners ever reach that level. If you are deciding whether your own offer or current pay is reasonable, work out which of those four bands you would fall into and use that as your reference point.

Biotechnology lead data manager gender pay gap in Sierra Leone
The gender pay gap is a stubborn feature of almost every labour market, and Sierra Leone is no exception. Male biotechnology lead data managers in Sierra Leone earn an average of 70,318,900 SLL a year, while female biotechnology lead data managers earn around 62,041,800 SLL.

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.
