Starting out with:
Do men and women earn the same amount of money?
Dependent variable – amount of money (in a year / life span?)
Independent variables – individual ones – highest examination, age, working years, regional ones, economic sector, …
Classifications for education examination (ISCED), regional and economic sectors, bargaining arragements, etc.

Public perception in Germany
• Gap is a result of discrimination against women
• NSI-Destatis reporting 18.3.2014[1]
• adjusted and unadjusted pay gap• Methodology: calculation takes individual variables into
account (age, gender, working hours, branches, education, …)
• press releases and methodological report (2006)• Results:
• Job characteristics make the difference• Pay gap as result of discontinuity, e.g. baby leave• unadjusted gap: 22% (2010, 2012)• adjusted gap: 7% (2010)

Example - Equal Pay Day Reporting in Germany
Trend-setting media: TV
• ARD (public tv 21.3.2014) • Tagesschau – prime time[1] : 22 % less money than men in
average – that is the reality for women in Germany. … Even if women work as much and as good as their male colleagues their payment is obviously less.
• ZDF (public tv 21.3.2014) • Heute– prime time[2] : only 22% mentioned• “Volle Kanne”[3] (Morning tv 9:00) – very differentiated,
expert from university

Summing up
Media reports: “Equal Pay Day”• TV - fragmentary • Radio - less differentiated• Newspaper – quite differentiated
Challenge for the end-user to understand• … when relying on public tv and radio
NSI dissemination – recommendations (Germany)• should be the guarantor to focus the topic from all sides
available (with data from official statistics)….• more anticipation of possible usage
