Population scenarios derived for the FSEC MAgPIE scenarios

Population scenarios for SSP1 and SSP2, derived using the `calcGridPop_new` function in the `mrmagpie` package (version 1.23.15). Underlying this function is the population scenarios of Jones and O'Neill (2016). This data set is archived for use in the MAgPIE scenario analyses, which were derived by the Food System Economics Commission. -- References B Jones and B C O'Neill 2016 <em>Environ. Res.
