• January/March 2012: agents will complete collection of census information.

In the field operation it is anticiapted that there will be available:

• 4,000 interviewing agents.
• 800 group supervisors (one for every five agents)
• 160 regional managers (one for every five group supervisors)

The selection of the interviewing personnel will be carried out, initially, from among those members of the job centre already existing in the INE. If necessary, personnel will be requested from the offices of the Public Employment Services, and therefore, a compulsory requirement will be to be registered as having applied for these Services.
