The printed forms will be filled out from 21st May 2011 to 6th June 2011. However, those interested in online counting should notice that the time available for completing the Census Sheets is shorter. According to the Government Regulation on the Census Period, data in electronic form will be collected from 21st – 29th May 2011. The reason for the shorter time is to ensure the integrity of the census enumeration on the whole territory of the Slovak Republic.
