Under natural conditions, mortality rates for girls under five are slightly lower than boys for biological reasons. However, after birth, neglect and diverting resources to male children can lead to some countries having a skewed ratio with more boys than girls, with such practices killing an approximate 230,000 girls under five in India each year. While sex-selective abortion is more common among the higher income population, who can access medical technology, abuse after birth, such as infanticide and abandonment, is more common among the lower income population. Female infanticide in Pakistan is a common practice.
