The geographic units represented by each record in area-level data or for which contextual variables attached to microdata are reported are selected in the Output & Transformation Options stage of the TerraPop workflow. After you have selected variables and datasets, clicked Continue from the Data Cart, and chosen the data format for your extract (area-level, microdata, or raster), you will see a geographic level selection screen. You can choose national, first-level, and/or second-level administrative units. By default, harmonized units are selected. You can also choose to include year-specific units.
