Rajasthan is the largest state in India by area and the most physically varied — a desert in the west, the oldest fold mountains in the country running through its middle, river-built plains in the east and a lava plateau in the south-east. Geography is the block where the largest number of Prelims facts are simply lookups: which district a river rises in, which soil belongs to which region, which peak is highest. They are gettable marks, and they are lost to imprecision rather than to difficulty.

Two rules govern every page in this unit.

Every figure carries an as-of date. Rajasthan's numbers move: districts were reorganised twice between 2023 and 2024, forest cover is re-surveyed every two years, tiger reserves have been added, and crop and mineral output changes annually. A figure without a date silently rots, and a page that hides the date of its data is not telling you how much to trust it.

Where a source is out of date, the page says so rather than repeating it. The standard state textbooks still print administrative figures that were superseded in December 2024. Those figures are shown here only as superseded, never as current.
