Explanations:The number of electoral constituencies in a region is determined by the population density of that area. Electoral constituencies are geographical areas that elect representatives to a legislative body, such as a parliament or a state assembly. The principle behind this system is to ensure that each representative serves a similar number of constituents, thereby providing fair representation.
In the context of the question, Mumbai is a densely populated city with a high concentration of people in a relatively small area. This high population density necessitates a larger number of electoral constituencies to ensure that each representative can effectively serve a manageable number of constituents. On the other hand, Rajasthan, particularly its desert regions, is sparsely populated, meaning there are fewer people spread over a larger area. As a result, fewer electoral constituencies are required to represent the population adequately.
It is important to note that factors such as literacy rates, the type of terrain, and the quality of infrastructure, while important in their own right, do not directly influence the number of electoral constituencies. The primary criterion is the population density, which is why Mumbai, being densely populated, has more constituencies than the sparsely populated deserts of Rajasthan.
Understanding this concept is crucial for comprehending how electoral systems function and how they ensure fair representation. It is also relevant for competitive examinations where questions on governance, political systems, and demographics are common.
