The 2011 Population and Housing Census (PHC 2011) is conducted in two stages:
For the purpose of the interview census, Estonia has been divided into three regions, which are further divided into districts, supervision areas and enumeration areas.
There are 15 districts – five in Tallinn and ten in the rest of Estonia. The central offices of districts are located in nine other cities in addition to Tallinn: Pärnu, Haapsalu, Narva, Jõhvi, Viljandi, Paide, Tartu, Rakvere and Võru. The conduct of the census in each district is managed by district heads who are in charge of supervisors. A district can comprise 8 to 10 supervision areas.
The total number of supervision areas is 132, with each of them having 14 to 16 enumeration areas. Supervisors oversee the work of the enumerators.
An enumeration area is the working area of one enumerator. There are 2,000 enumerators in total across Estonia, incl. enumerators of institutions (social welfare institutions and others). In addition, 200 enumerators are on standby, ready to be called if there is a need to substitute for an enumerator in an area due to illness or other reasons.
