우표와 엽서가 인도의 인구 조사를 돕다

In 1947, India became a new, independent country. The government had a big problem. They did not know how many people lived there. They needed to count everyone.

Counting so many people was very hard. India is a huge country. Roads were bad. Many villages were far away. The government needed a new idea.

The post office had a plan. India had post offices in many towns and villages. Workers in post offices could help count people. They used special postcards and stamps. These tools helped them collect information about families.

The postcards had simple questions. How many people live here? What are their names? How old are they? People filled out the postcards. Then they sent them back to the post office.

Stamps were also important. They showed which postcards were official. Stamps helped people trust the information. When people saw the stamp, they knew the form was real.

Letters traveled between villages and the main office. They carried the information about people. Workers organized all the information. Slowly, the government began to understand India's population.

This method worked very well. It was creative and smart. The post office became the heart of the counting project. Young country, old system—but together they succeeded.

Today, India still counts its people every ten years. But this first count was special. It showed how one simple system could help a new nation learn about itself.
