-# uk_census_shapes_clipped
-R Script used to clip UK census admin polygons to buildings layer from Ordnance Survey
+# UK Census Polygons - Clipped!
+
+Choropleth visualisations of data can often end up visually misleading in that they colour in polygons which contain vast tracts of uninhabited land. A more accurate visual communication can be achieved by clipping administrative polygons to data on the presence of buildings, that is, only using choropleth shading for areas which are inhabited.
+
+It is time consuming to produce this data, so I have done so programatically and uploaded the resulting geopackage files to a public repository for easy re-use for reproducible research. 
+
+The files in this repository are only the code used to produce those files. Separate licenses apply to that data etc.
