Global Research: Pink or blue – does a baby’s gender matter?

Family Research - Mothers long for a daughter

''Hoping for a girl this time?''. This is the question that expectant mothers are often asked if they already have a brood of boys.

Our team at MyHeritage.com thought they'd look into this theory and the resulting research, outlined below, indicates not only that parents do keep trying for a girl but that the desire to have children of both genders is a major driver of large families around the world.

Read on to find out more about these unique findings!

The most profound statistic was that families with 2 boys were almost 23% more likely to have more children than families with a boy and a girl, indicating a strong will amongst parents to produce a girl.

Data for families with 2 or 3 girls also showed that there was a notable percentage 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.

The findings were based on analysing worldwide family tree data from over 600,000 families, who bore at least 3 to 4 children from 1990 until 2010.

The table below divides the research into three categories - Global, United Kingdom and USA, and shows the number and percentage of families who continue to reproduce after 2 and 3 children of varying gender composites. For example - out of 617154 families around the world - 172048 (equal to 27.9%) had a third child following 2 boys.

Families with 3 children and more (those who had more children after 2):

First Children Gender All countries UK   USA  
Female-Female 165851 26.9% 7653 27.3% 36077 26.9%
Female-Male 140056 22.7% 6138 21.9% 30177 22.5%
Male-Female 139199 22.6% 6158 22.0% 30136 22.5%
Male-Male 172048 27.9% 8059 28.8% 37747 28.1%
Total 617154   28008   134137  

Families with 4 children and more (those who had more children after 3):

First Children Gender All countries UK   USA  
Female-Female-Female 19049 14.1% 998 15.4% 4976 14.3%
Female-Female-Male 16315 12.1% 774 11.9% 4258 12.2%
Female-Male-Female 16902 12.5% 719 11.1% 3923 11.3%
Female-Male-Male 15853 11.7% 755 11.6% 4179 12.0%
Male-Female-Female 15288 11.3% 751 11.6% 3984 11.4%
Male-Female-Male 15053 11.1% 710 10.9% 3852 11.0%
Male-Male-Female 16106 11.9% 741 11.4% 4210 12.1%
Male-Male-Male 20691 15.3% 1039 16.0% 5488 15.7%
Total 135257   6487   34870  

Global power couple, David and Victoria Beckham, (currently expecting their first girl) 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.

We'd love to hear your opinions on these family statistics. Are they consistent with your own real life experiences or those of family and friends?

  1. Hi,
    Do we need hope or we can do sth about our baby gender?
  2. I guess a baby's gender is not important. What's important is that the baby is safe and healthy.
