The world’s poorest countries have the highest child abuse rates in the developed world.
In 2017, nearly half of children under five in India, Niger, China and Bangladesh were abused.
The U.S. has the second-highest child abuse rate, with more than 40 percent of children being abused, according to the report released Wednesday by the Child Abuse Prevention Center at The Johns Hopkins Bloomberg School of Public Health.
The top five countries with the highest rates of child abuse were India, Nigeria, Vietnam, Syria and the Philippines.
The report said that, over the past three decades, the number of children abused worldwide has risen from more than 3.4 million to more than 4.1 million.
The data also shows that the number and severity of abuse in some countries has increased.
In India, for instance, the U.N. estimates that the rate of child sexual abuse in 2017 was 1,000 per 100,000 children.
In China, the total number of reported cases of child sex abuse has increased to 1.1 billion from 2.5 billion in 2017.
The United States reported the highest number of reports of abuse and physical and sexual abuse, which was the third-highest, after Vietnam and the United Kingdom.
In all, the report said, there were more than 6.6 million child sexual assault and physical abuse reports in 2017, a rise of more than 200,000 from the previous year.
In Bangladesh, the child sexual exploitation crisis in 2017 is estimated to have reached nearly 1.5 million victims.
India’s child sexual violence crisis in the past decade, which began with the death of a 10-year-old girl in Delhi in 2015, has become the country’s largest-ever child sexual security crisis.
India reported more than 1.7 million reported cases in 2017 as compared with 2.3 million in 2017 in 2017; the rate has nearly doubled in the same period.
“India’s child sex violence crisis is among the most serious and persistent in the world, surpassing those of China and the U
