# Oil rents (% of GDP)
The **"Oil rents (% of GDP)"** indicator measures the difference between the **value of crude oil production at world prices** and the **total costs of production**, expressed as a **percentage of a country's Gross Domestic Product (GDP)**.
Essentially, this indicator reflects the **economic value derived from oil extraction relative to the size of the economy**, providing insight into how significant oil revenues are to the national economy.
This metric can be particularly important for understanding the **dependence of a country's economy on oil resources** and the **impact of oil price fluctuations on economic stability**.
