  • Updated description of MapSPAM AggRurPop from

    This dataset is part of the MapSPAM series on spatial production. It is produced as interim result using GPW v4.0 population data as input. The aggregated rural population density is derived from the GPW data based on the assumption, that cropland lies within these grids. The dataset shows the population living in rural areas and is used to estimate the market accessibility and to account for subsistence production. "For SPAM 2010, we aggregate the population count grid to a 5 arcmin resolution and recalculate the population density. Then we derive rural population density (AggRurPopi) based on the assumption that if there is cropland within the 5 arcmin grids, then the population residing within the grids should be rural people. We do not aim to distinguish rural area from urban area. Instead, the variable AggRurPopi is introduced to estimate the market accessibility and to account for subsistence production." <br> *Yu, Qiangyi; You, Liangzhi; Wood-Sichra, Ulrike; Ru, Yating; Joglekar, Alison K.
