The last census in India was conducted in 2021. The census is a survey of the population of a country or region. It is conducted by the government to collect data on the population’s size, age, sex, education, and other characteristics. The data collected by the census is used to plan for the future, such as by determining how many schools and hospitals are needed.
The first census in India was conducted in 1872. The census is conducted every 10 years. The 2021 census was the 15th census in India.
The 2021 census found that the population of India was 1,393,015,923. This is an increase of 18.9% from the population of 1,210,193,422 in 2011. The growth rate of the population has slowed down since the 2001 census, when the population grew by 21.5%.
The 2021 census also found that the sex ratio in India is 929 females per 1,000 males. This is an improvement from the sex ratio of 940 females per 1,000 males in 2011. The sex ratio is the number of females per 1,000 males. A sex ratio of 1,000 means that there are equal numbers of males and females. A sex ratio below 1,000 means that there are more males than females. A sex ratio above 1,000 means that there are more females than males.
The 2021 census also found that the literacy rate in India is 77.7%. This is an increase from the literacy rate of 74.04% in 2011. The literacy rate is the percentage of the population aged 7 and above that can read and write.
