- CDU and CSU have been more popular among women every time except 1980 and 2002, which is quite telling because these were the only elections where the CDU/CSU chancellor candidate was from the CSU (Schmidt [SPD] vs. Strauß [CSU] in 1980 and Schröder [SPD] vs. Stoiber [CSU] in 2002).
The gender gap was particularly wide in 1953-1969 and then in 1972 it suddenly narrowed from 10 percentage points to 3 percentage points.
In 2013 the results were 44.3% among women vs. 38.6% among men, a gap of 5.7% quite similar to the one from 2009 (5.4%), but much higher than the one from 2005 (0.7%)
- The SPD was stronger among men in 1953-1969. After that the gender gap was almost non-existent, except for 2002 and 2005, when women gave the SPD 3.5 and 2.7 percentage points more than men respectively.
In 2013 the results were 26.6% among men and 25.0% among women.
- The FDP has always been a bit more successful with men than with women, except for 1980. The proportional gap in recent elections has been slightly wider than in the past.
In 2013 the results were 5.5% among men and 4.1% among women.
- The Left (and its predecessor PDS) has always been a bit more successful with men than with women. The gap was particularly wide in 2005 and 2009.
In 2013 the results were 9.1% among men and 8.1% among women.
- The Greens were stronger among men in the 80s, but stronger among women in recent elections. The gap has widened.
In 2013 the results were 7.3% among men and 9.6% among women.
- "Others" have always been more successful among men, in particular in 1969, when the NPD got 4.3% and was included into the "others" (5.6%), "others" got 7.7% among men and 3.7% among women.
In 2013 "others" (including the AfD at 4.7%) received 13.0% from men and 9.0% from women.
