(i) Major concentrations of modem manufacturing have flourished in a few number of places. These cover less than 10% of the world’s land area. 

(ii) However, in terms of the total area covered, manufacturing sites are much less conspicuous and concentrated on much smaller areas than that of agriculture due to greater intensity of processes. 

(iii) High tech is the latest generation of manufacturing activities. Professional workers make up for large number of the total work force. 

(iv) These professionally skilled workers are located in urban areas. Due to high rent in the central areas of the cities, they situate themselves in the periphery. 

(v) The industry is situated in the periphery because of the low rent, and also because of the closeness to the urban centres which provide them with availability of the workers. 

(vi) These industries are set up near the urban centres where adequate space is available. Their situation near urban places helps them to gain access to the urban market and also to tap the skilled workforce that is available therein due to availability of educational institutes.
