Dad of Divas' Reviews: The XY Factor - MyHeritage reveals couples' desire to produce offspring of different sexes

Tuesday, April 5, 2011

The XY Factor - MyHeritage reveals couples' desire to produce offspring of different sexes, the most popular family network on the web, today announced a result of its global family research – indicating that a key driver of large families is the desire to produce offspring of different genders. The most profound finding for the US market was that the number of families with 2 boys who continue to have children was almost 25% higher than families who already have a boy and a girl and decide to grow their family. This indicates a strong will amongst parents to produce a girl. The findings were based on worldwide family tree data of more than 600,000 families.

The research, one of the first of its kind to examine such family dynamics, is consistent with a long-standing myth that many women want to have a girl, and that many families ‘keep going’ until they have children of both genders. Famous celebrity couple, David and Victoria Beckham, fall into the category of 15.3% of families worldwide with 3 boys who choose to have another child – 22.4% higher than families with 3 children of mixed gender who continue to reproduce.
Data for families with 2 or 3 girls also showed that there was a significant difference in those continuing to have children, compared to same sized families with mixed gender children - possibly driven by the desire to produce a boy. These global differences were 15% and 12.8% higher for families with 2 and 3 girls respectively, and 19.6% and 17.2% higher respectively for families in the USA.

“People often ask expectant mothers if they’re ‘hoping for a girl this time?’”, said Laurence Harris, UK Genealogy Manager for “Up until now this has simply been an innocent and light hearted presumption if they have only boys. Now we can show that in many cases it’s true!
