Secondary Sector Share
Secondary Sector Share by country
Commentary
Notable countries
Guyana has the highest secondary sector share at 76.03% of GDP, followed closely by Libya at 73.5%, with several hydrocarbon-heavy economies such as Brunei, Qatar, Kuwait, Oman, Iraq and Saudi Arabia also dominating the top 10. At the other end, Lebanon records the lowest share at 2.09%, alongside very low values in Sao Tome and Principe, Micronesia and Vanuatu. A notable surprise is Luxembourg, which ranks among the bottom 10 at 9.66% despite being a high-income economy.
Regional trends
South America has the highest continental average at 31.83%, narrowly ahead of Asia at 31.45%, both well above the global mean of 25.58%. Africa sits close to the world average at 25.9%, while Europe (22.34%) and North America (21.12%) are lower. Oceania has the lowest regional average at 16.15%, consistent with several of the weakest country-level results appearing there.
Data source
The data come from the World Bank 2024 and measure the secondary sector share as a percentage of GDP. Coverage includes 189 countries. Values show the size of the secondary sector in national output, so cross-country differences may reflect economic structure rather than overall income or development alone.
Interpretation
Higher values indicate a larger contribution from industry and related secondary activities to GDP, which is treated here as better. Very high shares can signal strong industrial or resource-processing activity, while very low shares point to economies dominated by services or other sectors. Overall, the data show wide variation, with resource-rich countries often at the top and more service-oriented economies concentrated near the bottom.
