53% of all children born in Philippines were illegitimate

53% of all children born in Philippines were illegitimate (c. 2015). In addition to these 53% children born out of wedlock, there are many more broken marriages and separated couple who are not producing kids but in the past had the legitimate children.A wide range of research from sociologists and psychologists has shown that pre-adolescent children of single-parent families are more likely to have difficulties with emotional and psychological adjustment and with school performance and educational attainment, and they are also more likely to have behavioral adjustment problems.
Moreover, this age group is noted to progress certain difficulties in their future marriage, and earlier childbearing compared with children of two-parent families. Because single-parent children appear more vulnerable to a wide variety of societal problems, these children have been routinely referred to as at risk for developmental difficulties (Bornstein, 2002 p.109-110).
