The six maps on this plate show the distribution of manufacturing plants for industries which use metal as their primary raw material. The specific map titles are: Railway Rolling Stock, Motor Vehicles and Agricultural Machinery, Electrical Apparatus and Supplies, Aircraft and Parts, Motor Vehicle Parts, and Other Machinery. For each map, there are dots (or symbols representing many dots in a single locality) showing the location of a single factory. Each map also has two summary charts associated with it. One of these is a bar graph showing the selling value of major products of the specific industry type, while the other is a pie chart showing the provincial distribution of the persons employed in that industry. All data are as of 1954.
