India Place Finder – A cutting edge GIS tool

A cutting edge geographic information system tool to track the Indian diaspora has been developed by Dr. Tsukasa Mizushima, a professor at Tokyo University. Dr. Mizushima and his colleagues have developed the "India Place Finder", a web-based application that allows researchers to find geographic information about any place (known as toponym) in India. All places listed in the 2001 Census of India can be found via this tool.

Why is the tool useful to researchers?
Researchers can query a place by either sorting through the list, or narrowing the results by the State, District, or Sub-District. This might sound a lot like Google maps – but it offers more. The tool provides comprehensive topological context to a place, reaching back to 18th century India until 2001.

For example, if you search for “Chennai”, the tool shows all matches for Chennai within India, both on a grid (with State, District, Sub-District, Census Code, Latitude, and Longitude) and a map. In addition, all notation fluctuations are also considered and therefore, other places similar to Chennai appear in the results; in this case places like Chenai, Chen and so on also appear on the grid and on the map. Upon zooming into any location, you can find a detailed satellite or topological map.

So far, 900,000 villages have been included. Researchers can now track relatively obscure places on the maps with exact coordinates, prior to conducting field work. The tool is free to use, and easy to operate. The tool can be used to search one place at a time (Single Mode), or multiple places at a time (CSV Mode).

Information from Census 2001 and 4,500 Survey of India topological maps from 1869 onward have been used to create this vast database. The Government of India restricts the usage of Survey of India maps and the digital framework around Census information. Thus in order to make the map more comprehensive, Dr. Mizushima worked with libraries and with open data sources to develop these maps. For instance, Census 2001 district handbooks were used to map the villages that appear on the tool.

Dr. Mizushima is currently a professor of South Asian History at the Graduate School of Humanities and Sociology at Tokyo University, and specializes in the Indian geographic and demographic history


  1. Great find! This is a superb example of how a patient, long-term investment in understanding and transforming existing data can be revolutionary. The time and effort involved in creating this dataset is astounding, but the payoffs are huge. The India Place Finder is a gift to those of us conducting research in India. It would be great to hear more reporting on fresh Indian datasets with broad application to the research community. Far too often, great work isn't publicized. Thanks for the post.

Vocationalisation of education in India: Current Scenario, Key Challenges and New directions

“Every handicraft has to be taught not merely mechanically as is done today, but scientifically. This is to say, the child should learn the why and wherefore of every process.” - Gandhi’s Philosophy of Education

The greatest challenge in Indian education system today is to provide skill based education to the youth. This is exacerbated by a mismatch in demand and supply for the skilled workforce. The penetration of vocational education and training remains poor not only in rural areas, but also in urban regions where there is a higher installed capacity to impart the same. This post is an attempt to make the readers understand the need of vocational education in India. Also, this is an attempt to summarise a few recommendations on the same. 
A recent survey (61st round) conducted by the NSSO found that:

1. The percentage of population that completed primary education was 70%, but less than 10% went on to complete a graduation course and above. Almost 97% of individuals in the age bracket…

Rockstar of Financial Inclusion: Business Correspondent Model of India

India is a hot bed of financial exclusion. A country which houses nearly 16% of the global population  has more than 65% of its people outside the formal financial system (Global Findex 2012). The Indian banking system has adopted multiple approaches to make universal financial inclusion a reality right from early days Indian post-independence banking system. Be it bank nationalization in 1969 or formation of Regional Rural Banks. Formation of NABARD or fostering microfinance through Bank-SHG linkage programme in early 90’s. A shimmering ray hope was rekindled with the growth of JLG based microfinance, however later studies made it clear that the model is credit led, concentrated predominately in the southern region of India thus could not be seen as painting complete financial…

A Platform for Knowledge - Enabling people to learn ..

I received a rather interesting link/website via my email today. The link read as MR University and all I could think of was, "Ok, this must be another website portal of some university or college". Well, on clicking the link and looking through the contents of the site, I was pleasantly surprised. The site is an online education portal or platform that allows users or teachers to upload short videos on topics or lessons they wish to impart. First topic that I come across is Development Economics.
The intent of the website is eloquently put out by the two economists, Tyler Cowen and Alex Tabarrok in the intro video. What started as a blog focusing on economics and its various implications in understanding why things are the way they are around us, has now an interesting addition. A video portal titled MRUniversity or Marginal Revolution University that focuses on online education with subjects pertaining to economics. It brought back to my mind,…
