Summary The Pitney Bowes’ India Demographics Version 2 data product is based on the 2011 Census results. The data suite (layers) includes: 1. Census of India Demographics (2011): The census is a national survey which gathers information about the people living in India. The census data in this release are tabulated at the Country, State / Union Territory (36 records), District (642 records), Tehsil [Sub District (5990 records)] and Village / Town (634,035 records) levels. Please note that the Village level of geography is the lowest administrative level in rural areas, and the Town is the second lowest geography level in urban areas for which the census boundaries are available. 2. Population Distribution Model: The Population Distribution Model (PDM) represents spatial distribution of population density at each raster grid of 15 m x 15 m. In addition to vector data of four administrative levels – state, district, tehsil and village / town, this product provides raster data for the 36 states of India in .mrr format which are readable and editable in MapInfo Raster. These grid files (15 m x15 m) have population density values associated with each grid cell within Tehsil boundaries. These values are calculated with respect to the residential area of landuse-landcover map. The uninhabited areas carry null values. Sources of Information Excel Geomatics and Pitney Bowes Benefits The data provides an understanding of the contextual demographics for census-based levels of geography and administrative areas in India. It provides a basis for making assessments about the characteristics of households of the area and the distribution as anticipated by the Landuse of the region and population. The data sets are based on authoritative census enumeration of the population by the Government of India (Ministry of Home Affairs). The PDM helps the customer to calculate the population at grid level (minimum at 15 m x15 m radius). The distribution map is scientifically driven using the Landuse classes and assigning the weights to each class and verified through field validation. Table Information The data are provided in the Proprietary MapInfo format, MRR for rasters and tab for Vectors as well as data. There will exist, up to four files (levels) for each release (*.tab, *.dat, *.id, *.ind, +mrr and * .map files). Census of India Geography and Demographics Tables Village / Town (Village Level) The Village boundary layer is comprised of the Village and the Town boundaries. The Village is the lowest administrative level in rural areas. There are approximately 626,018 Villages. The Town is the second lowest administrative level in urban areas. There are approximately 8,017 towns and each record is distinctly linked with a Village_Code_ID. International Demographics Product Release Notes - India Census 2011 (Version 2) 2 The Village_Code_ID is composed of 2-digit State (or Union Territory) Code, 3-digit District Code, 5-digit Tehsil Code, and 6-digit Town and Village (or Town) Code (TV Code). This code is assigned to each polygon in the Village / Town boundary file. • Permanent Location Code Number (PLCN) has been allocated to every Village within the State (or Union Territory) and not within a Sub-District as in the earlier censuses. It is assigned as one continuous number from the first Village in the first District to the last Village in the last District. The PLCN is an 8-digit unique location code number with the first six digits representing the code number of the Village (Village_code), and the last two digits are, by default, two zeros '00' for future provisions. These zeros are reserved as buffer to be used for coding any new Village(s) that may come up between the two existing Villages. Demographic Record Geographic Record Type Description Count Count Villages Village_Code_ID 634,035 603,734 (State_code+District_code+Tehsil_code+Village_code) Unique Villages Village_code or PLCN_Code 630,965 603,734 • While linking demographics and geography data, Pitney Bowes found that around 5% (31K) of records that are available in the demographics data have no geographic attribute. • Approximately, 4.49% (29K) inhabitant Village records have null population because of the forested areas (or other wilderness areas) and restricted areas that have null population. • There is a mismatch in the distinct geographic record count at the Tehsil level (5,990) and the Village level (5,955) caused by the 35 new Tehsils that haven’t been updated by the Census at the Village level. • Approximately, 0.5% (3K) records consist of Village code or PLCN code like ‘00000000’ or ‘000F0000’, therefore there is a difference in distinct records in Village_Code_ID and Village_code. Tehsil This refers to the Sub-District geography unit. There are 5,990 Tehsils in India and each Tehsil has a unique code (Tehsil_ Code_ID). The Tehsil_ Code_ID is composed of 2-digit State (or Union Territory) Code, 3-digit District Code, and 5-digit Tehsil Code. Demographic Record Geographic Record Type Description Count Count Tehsils Tehsil_Code_ID 5,990 5964 (State_code+District_code+Tehsil_code) Unique tehsils Tehsil_code 5924 5964 • The total number of distinct unique Tehsils are about 5,924, but the total number of records in the Tehsil boundaries level is 5,990, because some of the Tehsils fall into two distinct Districts. • There are 26 geographic records (polygons) that are missing because they are uninhabited or restricted areas1. 1 Restricted Areas Foreigners (Restricted Areas) Order 1968 states that a Restricted Area Permit (RAP) is required for non-Indians to visit certain areas in India.

Each District has its own unique identifier (district_code_id) that is composed of the 2- digit State (or Union Territory) Code, and 3-digit District Code. Demographic Record Geographic Record Type Description Count Count Districts District_code_ID 642 642 (State_code+District_code) Unique Districts District_Code 642 642 • There are two District records (representing 0.01% of District records) that have null population because of forest and restricted areas. State (or Union Territory) A state (or a Union Territory) is the main administrative division in India. There are 36 states (including 7 Union Territories) in India represented in the 2011 Census. Demographic Record Geographic Record Type Description Count Count State State Code 36 36 • The Census was published in 2011, therefore the state of Telangana is not included in this data set. This new state was announced as a separate official state in June 2014. Pitney Bowes has added Telangana in both demographics and geography data as per the Census Atlas and other sources.
