INTRODUCTIONINTRODUCTION

UNECE Work Session on Statistical Data Editing:

Vienna 21-23 April 2008

Heather Wagstaff and Thomas Burg

Two key purposes for census taking are:

1. to provide a solid basis for important political and/or economic decision making; and

2. to create a comprehensive set of reference data.

Hence, data editing is essential to ensure sufficient

quality of the final outputs.

Topic (vi): Methodologies for Editing Census Data

Recent years have seen a movement:

away from conventional census taking;

towards purely register based censuses.

Aim of Session (vi):

and technologies used in the latest census round or

planned for the near future.

Topic (vi): Methodologies for Editing Census Data

1. Lessons learned from prior censuses do move us in the

right direction to improve our processes.

2. Users of census data and subject matter experts are not

provided with enough information about editing.

3. When moving towards register based census there is a

clear need to research & investigate the impact of record

linkage to edit and imputation

4. Post census surveys are a helpful tool to both evaluate the

results and improve the processes
