Reports of domestic violence increased in March in many cities as the coronavirus pandemic has spread across the United States.

According to NBC News, a number of agencies across the country have seen an uptick in calls of domestic disputes as families have been ordered to shelter in place during the month of March.

NBC News reports that Houston (TX) police reportedly received about 300 more domestic violence calls in March than they did in February, a roughly 20% increase. Charlotte-Mecklenburg, NC, police fielded 517 additional calls about domestic violence in March compared to the same month last year.

Similar increases in domestic violence have historically been documented after natural disasters.
