The prevalence of single mothers as primary caregiver is a part of traditional parenting trends between mothers and fathers. Data supports these claims, showing that in comparison to men, women are doing more than two-thirds of all child caring and in some cases one hundred percent.  Of approximately 12 million single-parent homes in 2015, more than 80 percent were headed by single mothers.  This disproportionate statistic has been well- documented in multiple country contexts all around the world.  The United States Census Bureau found that today, one in four children under the age of 18, a total of million are being raised without a father at all.  Women all around the world have been perpetually socialized to adhere to traditional gender roles that place the majority of responsibility for childcare upon them. 
In nearly all countries, students living in single-parent families have lower achievement on average than students living in two-parent families (see Figure 2a). In the United States, the average raw achievement difference in math between students living in two-parent families and students living in single-parent families is 27 points, or roughly one grade level. The United States is one of six countries with achievement differences larger than 25 points. Belgium has the largest disparity in math achievement by family structure, at 35 points, followed by the Netherlands (29), and Poland, Japan, and the United Kingdom (27 to 28). On average across the 28 countries, students living in single-parent families score 18 points lower than students living in two-parent families.
At the start of the year, PPMD made its biggest investment ever -- $ to Jerry Mendell at Nationwide Children’s Hospital -- for a Phase 1 Safety trial of gene therapy in Duchenne. This new publication of data showing that the technology works very well in dogs gives us added evidence that gene therapy is ready to go into humans and supports our decision to invest heavily in this approach. While dogs and humans are not exactly the same, these results are so very encouraging. We look forward to working with Dr. Mendell and his team at Nationwide and Sarepta, our co-investors, to move this trial forward.
