How India used postcards, stamps to count its people
As India prepares for its 16th census and the eighth since its independence in 1947, a new exhibition is shedding light on how stamps, postmarks and letters were once used to promote public engagement with the national headcount.
Long before smartphones and digital platforms, India relied on its vast postal network to encourage participation in the census, one of the world's largest data-gathering exercises.
As the country prepares for its 16th census and the eighth since its independence in 1947, a new exhibition is shedding light on how stamps, postmarks and letters were once used to promote public engagement with the national headcount, reports the BBC.
Curated by Vikas Kumar, an economics professor at Azim Premji University in Bengaluru, the exhibition traces the postal system's role in supporting the census during the decades following independence.

Reliable demographic data was considered essential for the newly independent nation, both for conducting elections under universal adult franchise and for planning economic development.
The importance of the exercise was reflected in the passage of the Census Act in 1948, even before India's constitution was finalised.
Authorities, however, faced the challenge of persuading citizens to participate while maintaining communication between census workers and officials across a vast and largely rural country.
Public trust was particularly important, as earlier colonial-era censuses had faced resistance and allegations of manipulation.
The postal department emerged as a key tool in addressing these challenges.
At the time, it was India's largest communication network and expanded rapidly after independence. By 1968, more than 100,000 post offices were serving hundreds of thousands of villages across the country.
Ahead of the 1951 census, the Indian government introduced a bilingual pictorial postmark featuring a family of three and the words "Census of India" in Hindi and English.
The campaign was designed for a population with low literacy rates, where postmen often acted as readers, scribes and trusted intermediaries.
Census messaging evolved over time.
In 1961, postmarks urged people to ensure that every family member was counted.
A decade later, commemorative stamps celebrated the census as one of the world's largest administrative operations and highlighted the use of electronic computers to process data.
Later campaigns portrayed the census as a reflection of the nation, describing it as a "mirror of the nation" and a "group photograph of the nation."
Postal materials also increasingly linked census-taking with population-control campaigns.
According to Kumar, these artefacts illustrate how the state sought to build trust and legitimacy through everyday communication.
While India is now preparing for its first fully digital census using mobile applications, he argues that public awareness and trust remain as important as ever to ensuring accurate data collection.
