Measurement
In the absence of Indian poverty estimates for over a decade, the World Bank's estimates have become the key source of data for India. We track the methodological changes that underpin the Bank's new estimates, and their impact on Indian data.
Measurement
India's Periodic Labour Force Survey is a vital source of employment data, and drives research and policy. We track changes in its methodology and their implications, key uses of the dataset, and important debates around its methodology and findings.
Measurement
Capturing the true situation of manufacturing employment in India is a vital part of understanding its economy. We examine the implications of using different data sources to track manufacturing.
Measurement
Global growth standards used to define the levels of child stunting in India have been contentious. While a substantial body of research shows that the standards are not inaccurate, more context-specific growth references could also be useful.
Measurement
Accurate estimations of demographic trends are vital for planning. India has both a direct and an indirect system to count births and deaths. How did they develop, what works and doesn't, and how can they be improved?
Measurement
The 2022-23 and 2023-24 rounds of India's Periodic Labour Force Survey appeared to show large, unexplained deviations on several important indicators. Our research identifies the error that drove those swings.
Measurement
How the NFHS has evolved over time, how it collects its data, and key discussions and debates around it.
Measurement
By official statistics, India has the largest number of reported deaths from road accidents of any country. But these are likely significant underestimates.
Measurement
The National Family Health Survey consistently underestimates the proportion of young males and elderly females in India's population. Estimates of the sex ratio from the NFHS need to be used with caution.
Measurement
Literacy rates are rising fast in India. But how literacy is defined matters, as does the manner in which surveys on literacy are conducted, resulting in some illiterate people being missed from official statistics.
Measurement
Accurately estimating the incidence and mortality from diseases in India, including malaria, is challenging. We lay out the available data sources and explain our reasons behind using selected sources.
Measurement
Between censuses, and to plan for the future, countries rely on population projections. Understanding how these projections are made, as well as their past successes and failures, is vital.
Measurement
Consumption expenditure data is vital to the understanding of living standards in India. The latest official data offers a new window, but has also seen key changes in methodology.
Measurement
Why is it so difficult to accurately estimate how many people die every year, and of what?
Measurement
What is work in Indian statistics, how is work captured, and who is defined as unemployed.
