Hindi Belt

The Hindi Belt, also known as the Hindi Heartland or the Hindi speaking states, is a linguistic region encompassing parts of northern, central, eastern, and western India where various Northern, Central, Eastern and Western Indo-Aryan languages are spoken, which in a broader sense is termed as Hindi languages, with Standard Hindi (based on sanskritaized version of Dehlavi ) serving as the lingua franca of the region.
The term "Hindi belt" is sometimes also used to refer to the nine Indian states whose official language is Modern Standard Hindi, namely Bihar, Chhattisgarh, Haryana, Himachal Pradesh, Jharkhand, Madhya Pradesh, Rajasthan, Uttar Pradesh and Uttarakhand, as well as to the union territory of Chandigarh and the National Capital Territory of Delhi.
It is also sometimes broadly referred to as the Hindi–Urdu Belt or Hindustani Belt.
Hindi is part of the Indo-Aryan dialect continuum that lies within the cultural Hindi Belt in the northern plains of India. Hindi in this broad sense is a sociolinguistic rather than an ethnic concept.
This definition of Hindi is one of the ones used in the Indian census, and results in more than forty per cent of Indians being reported to be speakers of Hindi, though Hindi-area respondents vary as to whether they call their language Hindi or the actual name of their language. As defined in the 1991 census, Hindi has a broad and a narrow sense. The term "Hindi" is thus ambiguous. Before being identified as a separate language, Maithili was identified by the census as a Hindi dialect. Many such languages still struggle for recognition.
The broad sense covers a number of Central, East-Central, Eastern, and Northern Indo-Aryan languages, including the Bihari languages except Maithili, all the Rajasthani languages, and the Central Pahari languages. This is an area bounded on the west by Punjabi and Sindhi; on the south by Gujarati, Marathi, and Odia; on the east by Maithili and Bengali; and on the north by Nepali, Dogri, Kashmiri, Western Pahari and Tibetic languages. The varieties of this belt are usually considered separate languages, as opposed to dialects of a single language as considered by the Indian census.
In a middle sense, Hindi is equated with the Central Indo-Aryan languages. Based on their linguistic features, these are divided into Western and Eastern Hindi languages. The narrowest definition of Hindi is that of the official language, Modern Standard Hindi, a standardised register a Western Hindi language spoken around Delhi and Western UP. Standardised Hindustani—including both Standard Hindi and Urdu—is historically based on the Khariboli of 17th-century Delhi.
Population data from 2011 Indian Census is as follows:
According to the 2001 Indian census, 258 million people in India (25% of the population) regarded their native language to be "Hindi", however, including other languages considered by the census as Hindi, this figure becomes 422 million Hindi speakers (41% of the population). These figures do not count 52 million Indians who considered their mother tongue to be "Urdu", which is mutually intelligible with Hindi. The numbers are also not directly comparable to the table above; for example, while independent estimates in 2001 counted 37 million speakers of Awadhi, in the 2001 census only 2½ million of these identified their language as "Awadhi" rather than as "Hindi".
There have been demands to include Awadhi, Bhojpuri, Kumaoni, Bundeli, Chhattisgarhi, Garhwali, Kudmali/Kurmali, Magahi, Nagpuri, and Rajasthani in the Eighth Schedule; these are otherwise regarded as dialects of Hindi by the government, although they have varying levels of mutual intelligibility with standard Hindi. Some academics oppose inclusion of Hindi dialects in the Eighth Schedule of the Constitution as full-fledged Indian languages. According to them recognition of Hindi dialects as separate languages would deprive Hindi of millions of its speakers and eventually no Hindi will be left.
Much of the Hindi spoken outside of the subcontinent is distinct from the Indian standard language. Fiji Hindi is a derived form of Awadhi, Bhojpuri, and including some English and very few native Fijian words. It is spoken by majority of Indo-Fijians. In Mauritius, Bhojpuri is the most commonly spoken Hindi dialect. Once widely spoken as a mother tongue at 31.7% in 1972, it has become less commonly spoken over the years. According to the 2022 census, Bhojpuri was the most commonly spoken language at home for only 5.1% of the population, though the per cent of the population fluent in the language is likely still around 36.7%, according to Anjani Murdan of the Mauritius Times.
The highly fertile, flat, alluvial Gangetic plain occupies the northern portion of the Hindi Heartland, the Vindhyas in Madhya Pradesh demarcate the southern boundary and the hills and dense forests of Jharkhand and Chhattisgarh lie in the east. The region has a predominantly subtropical climate, with cool winters, hot summers and moderate monsoons. The climate does vary with latitude somewhat, with winters getting cooler and rainfall decreasing. It can vary significantly with altitude, especially in Jharkhand and Chhattisgarh.
The Hindi Heartland supports about a third of India's population and occupies about a quarter of its geographical area. The population is concentrated along the fertile Ganges plain in the states of Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Jharkhand and Bihar.
Although the vast majority of the population is rural, significant urban cities include Chandigarh, Panchkula, Delhi, Lucknow, Kanpur, Raipur, Allahabad, Jaipur, Agra, Varanasi, Indore, Bhopal, Patna, Jamshedpur and Ranchi. The region hosts a diverse population, with various dialects of Hindi being spoken along with other Indian languages, and multi-religious population including Hindus, Muslims, Sikhs along with people from various castes and a significant tribal population.
Over the years political development in some of these states has been dominated by caste-based politics, but this has changed somewhat in recent years with the BJP national victory in 2014 and state victory in Uttar Pradesh in 2017. In 2019 election, 226 members from the Hindi belt states had been elected to the Lok Sabha.
