- Reorganizing hindi belt: UP, MP, Bihar, Rajasthan: a series of facts on proposed states
- Harit Pradesh or Pashchim Pradesh or Braj Pradesh or Doab
- Bhojpur: proposed state
- Awadh: proposed state
- Magadh: proposed state
- Mithila or Mithilanchal : proposed state
- Vidarbha: proposed state
- Greater Jharkhand: proposed state
- Malwa: proposed state
- Maru Pradesh or Thar: proposed state
- Greater Haryana: proposed state
- Bundelkhand or vindhya pradesh: proposed state
Regions included: Gwalior, Rewa, Sagar, Chambal, Shahdol & half Jabalpur divisions of MP and Jhansi, Chitrakoot divisions & Sonbhadra district of UP
Population (2011): 5 crores
Area: 200000 sq KM
Note: There is a long standing demand for Bundelkhand state but it has been turned down on the basis of lack of resources in the Bundelkhand region. If we include the Baghelkhand region in this proposed state than it can form a viable state. Even two separate states of Bundelkhand (Gwalior, Sagar, Chambal, Jhansi, Chitrakoot divisions) and Baghelkhand can be formed.
