Census of India 2001

Information on the contents of the CD on
village and town administrative units location codes

1. This CD contains the location codes adopted in Census 2001 for ensuring hundred percent coverage and also presentation of statistical data and maps. There are two different sets of codes namely the location codes for villages and the location codes for the towns. The Location Code Structure adopted in Census 2001 is described below

2. The general pattern followed in coding of any geographical unit was a serpentine one, except for the wards in the towns, beginning from the North-west corner and completing at the farthest South-east corner within the defined higher level of the geographical hierarchy. In so far as the State/Ut is concerned Jammu & Kashmir has code number 01 (north-west corner) and code number 35 (south east corner) has been allotted to Andaman & Nicobar Islands. Generally the administrative unit below a district is a sub-district, for example Tehsil or Taluk. However, in certain states and union territories exceptions had to be made since the nomenclature for sub-districts is not uniform throughout the country. For example, in Orissa Police station is the sub-district, in West Bengal it is the Community Development Block and so on. The geographical units adopted as sub-districts in various States and Union territories are listed in Annexure-I.

3. After the completion of Houselisting Operation, three new states namely, Uttaranchal, Chhattisgarh and Jharkhand were created in November, 2000 barely three months before the commencement of Population Enumeration.  These states were carved out of Uttar Pradesh, Madhya Pradesh and Bihar respectively.  This resulted in redoing the coding exercise in all the jurisdictional units of these six affected states and much time and effort initially put in had to be invested again to ensure that the processing of Houselisting records is not adversely affected among other things.

4. In Assam, Mizoram and Orissa there are a few sub-districts which cut across the district jurisdictions. In such situations these sub-districts only have been provided a separate series of code numbers beginning with 9 viz. 9000, 9001 etc., whereas those sub-districts which do not violate the district boundaries have been given the normal code numbers i.e. 0001, 0002 etc. the sub-districts which cut across two districts are  1) Sidli Circle (Kokrajhar and Bongaigaon districts), 2) Dhakuakhana Circle ( Lakhimpur and Dhemaji districts) and 3) Subansiri Circle (Lakhimpur and Dhemaji districts) in Assam, 4) Tlangnuam Rural Development Block (Kolasib and Aizawl districts), 5) Thingsulthliah Rural Development Block (Aizawl and Serchhip districts) and 6) East Lungdar Rural Development Block (Champhai and Serchhip districts) in Mizoram and 7) Ramagiri Police Station (Ganjam and Gajapati districts) in Orissa.

5. One of the major initiatives taken in the Census 2001 was the allotment of Permanent Location Code Number (PLCN) to each and every village within the State and not within a sub-district as in the earlier censuses. PLCN was thus assigned as one continuous number from the first village in the first district to the last village in the last district. PLCN is an eight digit unique location code number with the first six digits representing the code number of the village and the last two digits are by default two zeros '00' as future provision. These zeros are reserved as buffer to be used for coding any new village(s) that may come up between two existing villages in future. For example, if a new village comes up between two villages with PLCNs 01254600 and 01254700, the new village will be allotted PLCN 01254601 and so on.

6. There are 17 villages in Bihar and 12 villages in West Bengal which are spread across two sub-district. Two villages in Bihar cut across districts. These villages have been given same location codes although they appear twice in the database. The list of such villages is given in Annexure - II.

7. The location code number for a town in every state is also an eight digit number starting with the digit 4 situated at the extreme left acting as the unique identifier for any town in the state. The next two digits depict the code number of the district in which the town falls followed by two digits representing the town serial number in the district. There are three zeros at the end as buffer mainly to meet the requirement of bringing the number of digits to eight to match the number of digits in the PLCN for the villages. Thus a town location code number 40305000 represents the town serial number 5 of the district number 03 in a State.

8. There are ten towns in the country that spread over more than one district. These are 1) Devaprayag (Tehri Garhwal and Garhwal districts) in Uttranchal, 2) Delhi Municipal Corporation (all the nine districts) and 3) New Delhi Municipal Council (NDMC) (New Delhi, Central, Sourth West and South districts) in Delhi, 4) Imphal, Municipal Council (Imphal West and Imphal East districts), 5) Lilong, Nagar Panchayat, (Thoubal and Imphal East districts),  6) Nambol, Municipal Council (Bishmipur and Imphal West districts) and 7) Samurou, Nagar Panchayat, (Thoubal and Imphal West districts) in Manipur, 8) Siliguri, Municipal Corporation (Darjiling and Jalpaiguri districts) in West Bengal, 9) Greater Mumbai, Municipal Corporation (Mumbai Suburban and Mumbai districts) in Maharashtra and 10) Hyderabad Municipal Corporation (Hyderabad and Rangareddy districts) in Andhra Pradesh.  Although, the parts of such towns falling in two different districts have been coded independently, the last five digits of these towns are the same since the same town serial numbers have allotted within the districts to these different town parts. However, the district code being an element of the eight-digited town code structure; the same town has two different eight digited codes. For example, Siliguri (M.Corp.) falling in two districts, namely, Darjiling (01) and Jalpaiguri (02) has codes 40109000 and 40209000 respectively.

9.  A statement showing district-wise number of sub-districts, towns (statutory and census) and villages (inhabited and uninhabited) is given in Annexure – III.
