The number of US children orphaned during the Covid-19 pandemic may be larger than previously estimated, and the toll has been far greater among Black and Hispanic Americans, a new study suggests.

More than half the children who lost a primary caregiver during the pandemic belonged to those two racial groups, which make up about 40 per cent of the US population, according to the study published by the medical journal Pediatrics.

“These findings really highlight those children who have been left most vulnerable by the pandemic, and where additional resources should be directed,” one of the study’s authors, Dr Alexandra Blenkinsop of Imperial College London, said in a statement.

During 15 months of the nearly 19-month Covid-19 pandemic, more than 120,000 US children lost a parent or grandparent who was a primary provider of financial support and care, the study found. Another 22,000 children experienced the death of a secondary caregiver — for example, a grandparent who provided housing but not a child’s other basic needs.
