Data processing and documentation:
A transparent and interactive process:
• Data check, editing and validation is accomplished in interaction between the Archive (NSD) and the National Team of each participating country
• Standardized contact procedure between NSD and the National Teams
• Standardized data processing (work) procedure and programmes
• The data processing is documented in a two-step Data Processing Report

Reminder
The figure illustrates the ESS data processing work flow at NSD, as well as the communication between the National Teams and NSD from ”no file deposit” to inclusion of country file in the international integrated file
Every participating country is assigned a primary contact person from the ESS Data Team at NSD
The contact person takes care of the processing of the country’s data, and communicates with the National Team
The data processing is accomplished in two steps:
1. A data check process and
2. A data editing process
-Each step resulting in a Data processing summary
The data processing summaries from the two steps make up the Data Processing Report
European Social Survey
Documenting the data processing:
During the data processing period:
• The Data Processing Report, all programmes used etc. are made available for the National Teams during the data processing period through the European Social Survey Archive Web Site: http://essdata.nsd.uib.no
After the data processing period:
• The Data Processing Reports, all programmes used, e-mails etc. are stored at NSD
European Social Survey
What is published about NSD’s data processing work at the ESS Data Web Site (http://ess.nsd.uib.no) and in Nesstar?
• Information of the extent of processing checks and missing values
• The handling of detected deviations
• Version notes We are handling deviations in three ways:
• Flagging
• Removing deviating variables from the integrated file, keeping the information in a country specific file
• Creating a new variable with a country-specific name in the integrated file
Three ways of accessing information of how deviations have been handled at NSD:
• The Data Processing Report
• The Fieldwork Summary and deviations link
• Online presentation of data and documentation together in Nesstar
European Social Survey
In the Data Processing Report under ”Survey documentation” you will find information about
detected deviations
