In India, data on key developmental indicators that formulate policies and interventions are routinely available for the administrative units of districts but not for the political units of Parliamentary Constituencies (PC). Members of Parliament (MPs) in the Lok Sabha, each representing 543 PCs as per the 2014 India map, are the representatives with the most direct interaction with their constituents. The MPs are responsible for articulating the vision and the implementation of public policies at the national level and for their respective constituencies. In order for MPs to efficiently and effectively serve their people, and also for the constituents to understand the performance of their MPs, it is critical to produce the most accurate and up-to-date evidence on the state of health and well-being at the PC-level. However, absence of PC identifiers in nationally representative surveys or the Census has eluded an assessment of how a PC is doing with regards to key indicators of nutrition, health and development.

On this website, we report PC estimates for indicators of nutrition, health and development derived from two data sources:

The National Family Health Survey 4 (NFHS-4) District Factsheets
The National Sample Survey (NSS), 2010-11, 2011-12, 2014 (Author calculations) . . .

The PC estimates for each of the indicators are classified into quintiles for map visualizations. Currently, we provide map-based visualizations for a subset of indicators, and these will be continually updated for additional indicators. . . .

In addition to providing a visualization of indicators at the PC level, we also provide tables of the PC estimates. . . .

I’ve not looked at this all myself, but I thought it could be of interest to some of you.
