sektöR

Sektör is a Turkish noun meaning a broad area of economic activity or a field of activity. It designates a distinct part of the economy that groups firms and activities with common characteristics. The term is borrowed from the French secteur, reflecting its long-standing use in economics and public administration.

In macroeconomics and national accounting, sectors help describe the structure of an economy. The traditional three-sector model divides activity into primary (agriculture, mining), secondary (manufacturing, construction), and tertiary (services). Some analyses also recognize higher-order sectors such as the quaternary (knowledge-based services) and quinary sectors. National statistical agencies typically classify activities into sectors and subsectors, such as agriculture, industry, and services, with further subdivisions like manufacturing, wholesale and retail trade, transport, and finance.

Sectoral data support policy making and economic analysis. They are used to measure the contribution of each sector to gross domestic product, employment, productivity, and trade, and to monitor structural change over time. In Turkey, sectoral statistics are published by the Turkish Statistical Institute (TÜİK) and aligned with international classifications such as ISIC/NACE.

Common examples include the agricultural sector (tarım sektörü), the industrial sector (sanayi sektörü), the financial sector (finans sektörü), and the tourism sector (turizm sektörü). Sectors are not static; they evolve with technological advances, regulatory changes, and external shocks, which can shift resources and growth trajectories across the economy.
