Productivity of artificial land

Productivity of artificial land is defined as the gross domestic product (GDP) of a country divided by its total artificial land. Artificial land consists of built-up areas (areas covered with buildings and greenhouses) and non built-up areas (streets and sealed surfaces). Artificial land productivity shows whether built-up and non built-up areas are efficiently used to generate added economic value. For the calculation of artificial land productivity Eurostat uses the GDP in millions of PPS (Purchasing Power Standard). This unit allows to compare countries for the same year.
