Definition in Census The first category of urban units is known as Statutory Towns. These towns are notified under law by the concerned State/UT Government and have local bodies like municipal corporations, municipalities, municipal committees, etc., irrespective of their demographic characteristics. The second category of Towns is known as Census Town.<br>
05
Definition in Census City – A town with population more than 100,000. Out Growths (OG):
An Out Growth (OG) is a viable unit such as a village or a hamlet and clearly identifiable in terms of its boundaries and location. Examples are railway colony, university campus, port area, military camps, etc., which have come up near a statutory town outside its statutory limits but within the limits of a village or villages contiguous to the town. While determining the outgrowth of a town, it has been ensured that it possesses the urban features in terms of infrastructure and amenities such as durable roads, electricity, taps, drainage system for disposal of waste water etc. educational institutions, post offices, medical facilities, banks etc. and physically contiguous with a statutory town.<br>
06
Definition in Census Urban Agglomeration (UA):
An urban agglomeration is a continuous urban spread constituting a city/town and its adjoining outgrowths (OGs), or two or more physically contiguous towns together with or without OGs of such towns. An Urban Agglomeration must consist of at least a statutory town and its total population (i.e. all the constituents put together) should not be less than 20,000. In varying local conditions, there were similar other combinations which have been treated as urban agglomerations satisfying the basic condition of contiguity. Examples: Greater Mumbai UA, Delhi UA, Kolkata UA, etc.<br>

Difficulties with the proposed method of degree of urbanisation In the context of India, classification of urban-rural area by the degree of urbanisation method is likely to suffer from two aspects:
(i) operational and
(ii) conceptual<br>
10
Operational issues in context of India Network of grid:
There is no population grid system for identification of areas. Creation of Population grid by geo-referencing population statistics coming from population registers and population censuses or using contemporary high-resolution satellite imagery and sophisticated algorithms based on land use and land cover information is not possible because such technology is yet to be implemented for large scale operations. Division of areas of the country into grids and collecting statistics on them can only be undertaken during census operations.<br>
11
Operational issues in context of India Each statutory town in the country has been divided into a number of smaller area units called ‘Wards’. They have generally well defined demarcation of boundaries. Wards are political-administrative units within the limits of cities/towns. They have different sizes, infrastructure and population densities, e.g. Wards in the rich localities are generally less dense, have very good infrastructural facilities while wards having slums have congestion, high density, low infrastructure. Census operations in urban area and Ward / enumeration blocks:<br>
12
Operational issues in urban During census operations, smaller temporary areas are demarcated within each ward. These are called Census Enumeration Blocks (EB). They have typically a population of 600-800 persons. One EB is assigned to an enumerator who collects information for that EB. EBs are not uniform in size and encompasses an area which can be operationally convenient for listing of houses and households.<br>

Operational issues Switching over to grid system will derail the ward or village based information dissemination unless there is an overlapping and synchronisation at certain level is found to be feasible between the two.<br>
16
Conceptual Issues Comparison between the method followed in the country and the proposed method: Precise comparison cannot be done since no statistics on grid based system is available for the country. In the document (ghsl.jrc.ec.europa.eu) of the European Commission some statistics have been reported for countries. Comparison is done for population of few big Urban Agglomerations.<br>
17
Comparison of Population of few UAs Comparison shows wide divergences in population counts<br>
18
Conceptual Issues Within each UAs there are a number of towns besides the core city. For example, in the Kolkata UA, core city is Kolkata but there is also another big city (pop more than a million) and many small towns. Statistics are generated for each city/town separately for administering the policies and programmes. If ‘urban centre’ is formed considering the UA, then some of the smaller towns will be merged with city or other towns. How the statistics for individual towns are to be collated ? Some villages are there surrounding the big cities/towns. They have high densities (e.g. there are a number of villages in and around Delhi). Will they be considered as ‘urban centres’ or ‘urban clusters’?<br>
19
Conceptual Issues There are wide variations in the sizes of villages in India. As per the demographic patterns in the villages, people are concentrated in a few clusters even though area of the entire village is large. For big populous villages, the clusters may be dense. Number of villages by size of population can be seen in the next slide. Conceptual Issues<br>
20
Number of villages with high population Village population are generally clustered in certain pockets even though area may be large. Many of these pockets may satisfy the criteria of ‘urban centres’ or ‘urban clusters’. Will the villages therefore be classified as towns as per the new method ?<br>
21
Pros and Cons of the method We are therefore in a situation where perfect synchronisation is not possible between the methods proposed and the national classifications followed even if the grid system is implemented in future.
Current population and demographic statistics are entwined with national system of classifications which cannot be replaced in near future. 21<br>
22
Pros and Cons of the method It is no doubt important to focus on places where human settlements have high population density and take care of basic amenities there. SDG 11 targets cannot be achieved without the assigning priority on these areas.
The proposed method will also facilitate comparison among the regions of the world so that monitoring of targets will be easier. 22<br>
23
Pros and Cons of the method On the other hand, countries have short term and long term strategies based on the existing structure of urban-rural delineation. Altering the existing system will have serious implications for the strategies.
In India, priority is being given to develop Tier II and Tier III cities so that population pressure on Tier I cities can be controlled. If the contours of these cities are altered in order to conform to the global definition, there will be problems for administering development projects. 23<br>
24
Need for better synchronisation It is therefore, imperative to explore an alternative where global definition can be embedded into the national classification system rather than national classification tweaked to suit current global definition. 24<br>
