Reasons for High Densities • Intensive agriculture • Rich alluvial soils • Flat land • Climate • Industry • Trade • Communications

Reasons for Low Densities • Climate too cold too dry • Poor soils • Relief too high too exposed • Isolation

Map Activity Integrating Numeracy • Working out densities using multiplication • Working out average densities • Graded worksheet
