To map the population density of the entire country, we now have everything we need: a dataset of grid cells covering the entire country. STEP 3: Make a sub-selection of the current dataset Deselect the JRC_POPULATION_2018 feature class in the Contents pane. The output feature class contains only the population density grid cells for Holland. For the output feature class name, type “Population per sq/km in Holland”. Next, apply the Clip tool using the JRC_POPULATION_2018 file as input feature dataset and the Holland polygon as Clip features. Name it “Holland” and deselect the ne_10m_admin_0_countries.shp in the contents pane. Next, choose the Select Geoprocessing tool and run it to create a new feature class of that selected feature. To do this, you can draw a rectangle on the map using the Select tool in the Map menu on the ribbon interface. This is why we’ll make a selection of the data and analyze this: we’ll pick The Netherlands and only analyze data for this country. The EUROSTAT shapefile contains more than 2 million rows and is quite large.
