The six maps on this plate show employment and related patterns for the leading service sectors as compiled from the 1951 Census. There are two maps referring to wholesale trade. One of them shows the distribution of the labour force engaged in wholesale trade. This is shown by a dot pattern using one dot for every 200 people of this labour force, and using proportional symbols for all places employing 2 000 or more. The other wholesale trade map shows percentage of net value of sales from wholesale trade in each census division. There are two similar maps of retail trade. One, showing the distribution of labour force, uses the same mapping procedure as that of wholesale trade. The second map shows retail trade as a percentage of net value of sales for each census division. The fifth map shows the distribution of the construction labour force, using the same mapping concepts as for the wholesale trade map. There is an associated pie chart showing the types of construction this labour force engages in. The sixth map shows the distribution of labour force in the fire, insurance and real estate industries, again using the mapping concepts used for the wholesale trade map. This map is accompanied by a pie chart showing employment in the various industries of this group (such as in banking).
