Hi,

Census is an official count of people who resides in the country, including information about their jobs, ages.  The last time census happened was in 2011 and as it happens after every 10 years, so it was supposed to happen in 2021 but due to the outbreak of the covid 19, it got postponed and now the reports suggest that it may not even happen in the first half of 2022.

Hope this helps.
