How does TerraPop transform area-level data to rasters?
TerraPop can transform area-level data into raster data by distributing data about geographic units over the grid cells within each unit. TerraPop currently uses a uniform distribution assumption, meaning that every grid cell in a given geographic unit is assigned the same value. For count variables, like total population, the total count for the geographic unit is divided by the number of cells in the geographic unit and that value is assigned to each cell. For percentage or median-type variables, such as % unemployment, the value for the geographic unit is assigned to every cell in the unit.
