Census in Kerala
Prior to independence, Kerala formed part of, the two Princely States of Travancore and Cochin and of Madras Presidency. The earliest authentic account of census in this part of India is available from the "Geographical and Statistical Memoir of the Survey of Travancore and Cochin States" conducted by Lieutenants Ward and Conner during the period 1816-20. Thereafter censuses were taken in Travancore State in 1836 and Cochin State in 1854. But there are grounds to believe that frequent attempts were made by the earlier rulers of the State to collect statistics of the population and the resources of the country.
The first modern census of Travancore - Cochin was taken in 1875. From 1881 onwards the constitutional units of Kerala State had census taken at 10 year intervals with the rest of the country. The first census of this State of Kerala was taken in 1961. Thereafter, census was taken every 10 years. The last census was taken in 2011
