The national accounts have the task of providing, in quantitative terms, an overall picture of economic activity in Germany that is as clear and as comprehensive as possible. They include all economic agents (individuals, institutions) as well as their economic activities and related processes that are important for describing the business cycle. As part of the national accounts, calculations of domestic product provide data needed for ongoing economic observations and analysis, most notably quarterly and annual data on the creation, use and distribution of gross domestic product (GDP) at current prices or adjusted for inflation (or price change). The national accounts also include figures for the factors of production (employment rate, wealth accounts).
