Historical Background
The Government of India designated June 29 as National Statistics Day in 2007. The day is dedicated to Prof. Mahalanobis for his pioneering work in statistics, most notably the Mahalanobis distance, a statistical measure. His efforts led to the founding of the Indian Statistical Institute (ISI) and he played a key role in shaping the Planning Commission of India.
Significance of the Day
National Statistics Day underscores the role of statistics in empirical data analysis and its importance in designing and evaluating the country’s socio-economic policies. The day’s observance serves to raise public awareness about the role of statistics in various aspects of daily life and to encourage young people to pursue careers in this field.
Themes and Activities
Each year, National Statistics Day is celebrated with a specific theme pertinent to national development goals. Recent themes have included “Sustainable Development Goals (SDGs)”, “Quality Assurance in Official Statistics”, and “Data for Sustainable Development. Activities range from seminars and workshops to competitions and exhibitions, with the involvement of government agencies, academic institutions, and students.
Prof. Mahalanobis’s Legacy

The legacy of Prof. Mahalanobis is not only in theoretical statistics but also in large-scale sample surveys. His methodologies laid the foundation for the National Sample Survey Office (NSSO), which conducts large-scale surveys and provides essential data for planning and policy formulation.
The Role of Statistics in Modern India
In today’s data-driven age, statistics have become even more critical for India. From informing policy decisions to enabling businesses to analyze market trends, statistics are vital. The government relies on statistical data for initiatives like Digital India and Smart Cities, aimed at transforming the nation into a digitally empowered society and knowledge economy.
India and Statistics: Some Notable Wins
India has a long history of employing statistics effectively across various fields. Here are some examples where the use of statistics has led to successful outcomes:
- Aadhaar Project:
- The Aadhaar initiative is one of the world’s largest biometric ID systems. Statistical algorithms are used to ensure unique identification for over a billion people. These algorithms help in deduplication, ensuring that each individual is assigned a unique number.
- Agricultural Statistics:
- India’s extensive use of statistics in agriculture has enabled the government to forecast crop yields, plan the allocation of resources, and insure farmers against crop failure through schemes like Pradhan Mantri Fasal Bima Yojana (PMFBY).
- National Family Health Survey (NFHS):
- This large-scale, multi-round survey conducted in a representative sample of households throughout India provides essential data on health, family welfare, and nutrition. The findings influence policy and programs in the health sector.
- Indian Meteorological Department (IMD):
- The IMD uses statistical models to predict weather patterns and climate change effects. These predictions are vital for disaster management and for farmers in planning their sowing and harvesting activities.
- Census of India:
- Conducted every ten years, the Indian Census is the most comprehensive source of demographic and socio-economic data. It employs statistical techniques for data collection, analysis, and dissemination, influencing policy and planning at all levels of government.
- Economic Planning:
- The use of statistical data by the NITI Aayog (formerly Planning Commission) for economic planning and policy formulation has been critical. It involves analyzing data from various sectors like GDP, inflation, employment, and others to make informed decisions.
- National Sample Survey Office (NSSO):
- The NSSO conducts regular socioeconomic surveys that offer insights into poverty, employment, consumer expenditure, and more. These statistics are fundamental for policy decisions and understanding the impact of economic reforms.
- Polio Eradication:
- Statistics played a crucial role in India’s polio eradication programs. Through the careful analysis of outbreak data and vaccine coverage, strategies were formulated to target polio immunization drives effectively.
- COVID-19 Pandemic Response:
- During the COVID-19 pandemic, statistical models helped in predicting the spread of the virus, understanding the epidemiological trends, and formulating response strategies, including lockdowns and vaccination drives.
- Elections:
- The Election Commission of India uses statistical tools to analyze voter behaviors, plan logistics for elections, and ensure fair and efficient electoral processes across the country.
- Digital India Initiatives:
- Statistical analysis is fundamental to the Digital India program, which aims to provide government services to citizens electronically. Data analytics is used to monitor progress, understand user demographics, and optimize service delivery.
- Transport and Infrastructure:
- The Indian government uses statistical models to predict traffic patterns, which in turn inform infrastructure development like highways and urban transit systems.
- Education Sector Analysis:
- Through the use of statistics, the government assesses literacy rates, school enrollment, and the impact of educational programs, which helps in educational planning and reform.
The successful application of statistics in these areas showcases India’s commitment to data-driven decision-making for its socio-economic progress.
World Statistics Day
There is also a World Statistics Day, celebrated every five years on October 20th, established by the United Nations to recognize the importance of statistics in shaping our societies.
Challenges and the Road Ahead
While National Statistics Day celebrates achievements, it also brings attention to the challenges in the field of statistics, such as data quality and integrity. The goal ahead is to improve statistical methods, ensure the collection of timely and accurate data, and enhance the analytical skills of professionals in this domain.
Conclusion
National Statistics Day is a day of pride for India, recognizing the pivotal role of statistics in nation-building. It honors a visionary statistician, encourages statistical education, and emphasizes the ongoing importance of high-quality statistical data. As India progresses, the lessons of National Statistics Day will continue to guide its journey towards informed decision-making and strategic planning.
