Public perception in Germany

  • Gap is a result of discrimination against women
  • NSI-Destatisreporting 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)

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
    • “VolleKanne”[3] (Morning tv 9:00) – very differentiated, expert from university

    • Mixes up adjusted and unadjusted results
  • Public Radio – Radio Bremen[2]
    • Interview with Gender commissioner, quite differentiated

summing up
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
