Operations

A small set of indicator operations are also supported. Every indicator object except DatasetTable accepts an optional parameter operation. This parameter can take on the following values:

• change returns the difference of the specified attribute for the current year with respect to the baseyear (currently fixed at 2000).
• percent_change returns the percent difference of the specified attribute for the current year with respect to the baseyear (currently fixed at 2000).
• size returns the size of the data set used.

An example using operations:

Table(
    source_data = source_data,
    dataset_name = 'large_area',
    name = 'de_population_change',
    operation = 'change',
    years = [2015]
)
