An attempt has been made for the first time during the Census of India,
2001 to collect detailed data about slum areas of the country particularly in cities/towns having
50,000 population or more based on 1991 census. All the inhabitants of the areas, which have been
notified as slums by the state governments under any legal provisions or even recognized by them,
have been accordingly considered as slum population for this purpose. Besides areas in cities/towns,
which satisfy the usual criteria for declaring an area as slum have also been included.
For the purpose of Census of India, 2001, the
slum areas broadly constitute of :-
- All specified areas notified as 'Slum' by State/Local Government
and UT Administration under any Act;
- All areas recognized as 'Slum' by State/Local Government
and UT Administration which may have not been formally notified
as slum under any Act;
- A compact area of at least 300 population or about 60-70
households of poorly built congested tenements, in unhygienic
environment usually with inadequate infrastructure and lacking
in proper sanitary and drinking water facilities.
The Directorate of Census Operations in consultation with the State
Government/Local Authorities were asked to identify slum areas in municipal towns having population
of 50,000 or more as per 1991 census. Therefore, the estimates of slum population given below primarily
are confined to cities and towns having more than 50,000 population at the 1991 Census. Though the
criteria adopted for formation of slum EBs was confined to municipal towns having 50,000 population,
however, in a few stray cases even the non municipal towns were found to have large number of slum
areas, necessitating formation of slum EBs by the local authorities. For instance in National Capital
Region of Delhi, eleven Census towns and in Uttar Pradesh one Census town have reported slum population.
In addition to these, six towns, one in Bihar, two in Madhya Pradesh, two in Gujarat and one in Maharashtra,
could qualify the population criteria of 50,000 after adding population of outgrowths as returned for Census
of India, 1991. In case of Shillong, slum areas were notified in the entire urban agglomeration as such slum
population has been reported from the Shillong urban agglomeration.
TSlum population has been reported from 26 States/Union territories.
Nine States/Union territories, namely, Himachal Pradesh, Nagaland, Mizoram, Sikkim, Arunachal Pradesh, Manipur,
Dadra & Nagar Haveli, Daman & Diu and Lakshadweep have not reported any slum population in their cities/towns.
The first table on slum data is provided in two parts include
the number and population of cities/towns reporting slum, total slum population and slum population
in 0-6 age group and literate slum population by sex - India & State/Union territory. The second table,
also provided i two parts give population, slum population, and slum population in 0-6 age group and
literate slum population by sex in million plus cities.
