Industrial regionalisation / clusters/ agglomerations.
India has great diversity of industries and over the years industries have managed to disperse across the country but certain regions have developed as major industrial agglomerations and are today major industrial regions.
Most of the agglomerations have been either due to the raw material advantage or due to policies that have favoured investment and infrastructure in some regions.
According to to BN Sinha there are three types of industrial agglomerations.
- Major clusters - Employ greater than 15 lakh workers a day
- Minor clusters - Employ greater than 2.5 lakh workers a day
- Industrial districts - Employee 25 thousand workers a day
Most of the industrial clusters which are smaller and are at the level of a district are based on traditional skill sets.
