Fertility of Polish Senate members in 2015

Here is a bit of statistics about fertility of Polish senators in September 2015.

8 senators are childless
16 senators have 1 child
40 senators have 2 children
21 senators have 3 children
5 senators have 4 children
8 senators have 5 children
1 senator has 8 children

The average fertility of a Senate member is 2.27. The average family fertility in Poland is 1.41.

There is positive correlation between fertility and being involved in the so-called "democratic opposition" or among Solidarity leadership before 1990. The data contradict the claim of repressions of the communist dictatorship against members of the "democratic opposition". Purported repressions not only have not reduced fertility, but increased it! One would rather expect the opposite effect: the stress accompanying the underground activity resulting in reduced fertility.

The stachanovite in this area is a certain electrician and the first Solidarity leader having eight children, but he is not a senator. A recent President of Poland, allegedly strongly involved in the underground during 1980s has five children. Life under communism was hard enough even without repressions. It is reasonable to expect that the added effect of repressions would reduce fertility to below average among the "democratic opposition".

Seventeen percent of families in Poland have at least three children. This fraction among the senators is twice as large. Thirty five percent senators have at least three children. Thirty three percent of all children in Poland come from such families. Fifty eight percent of senators' children come families with three children or more.

Here is the raw data for all senators, in alphabetic order:

Thus, the fertility data contradict the official narrative. Instead the entire "democratic opposition" was organized, controlled and led by the communists themselves and their secret services. There is nothing unusal about it.
