New Ingrean Census of Population and Housing

The New Ingrean Census of Population and Housing is conducted every five years by the Statistics Agency. The census provides demographic and statistical data to the Government of New Ingrea that is used to plan the outlay of public services including health care, education, and transportation, determine the scope of funding to local government, and determine the number of Members of Parliament for each county.

There have been 25 censuses since 1841. The last census was held in August 2020, with the next scheduled to be held on 5 August 2025.
