Get the Investment to GDP Ratio for a variety of countries over time from the Global Macro Database (GMDB). The Investment to GDP Ratio is the ratio of the total amount of money spent by businesses on capital goods, such as machinery, equipment, and buildings to the Gross Domestic Product (GDP).

Data comes from the Global Macro Database (GMDB), further information about the variable can be found within https://www.globalmacrodata.com/documentation.html

The ratio is expressed as a decimal fraction (0.2248 for 22.48% of GDP).

Changed in v2.2.0: this used to be returned in percentage points. It is now a decimal fraction, matching every other ratio in the Finance Toolkit.

Also known as: investment rate.

  • countries (list[str] | str | None, optional): A list of countries or a single country to include in the results. Defaults to None.
  • rolling (int, optional): The rolling window size to use for smoothing the data (simple moving average). Defaults to None.
  • trailing (int, optional): The trailing window size to use for summing the data over trailing periods (e.g. a trailing-4-quarter sum). Defaults to None.
  • growth (bool, optional): Whether to return the growth data or the actual data. Defaults to False.
  • lag (int, optional): The number of periods to lag the growth data. Defaults to 1.
