US gun violence has led to the death of 27 people and 63 injuries across the country on Christmas Day this year, according to the Gun Violence Archive.

The shooting incidents, which do not include people who shot themselves in suicide, are a grim reminder that violence in America never takes a holiday.

The 27 people killed by guns in the US on Christmas is equal to the total number of people killed in gun homicides in an entire year in Austria, New Zealand, Norway, Slovenia, Estonia, Bermuda, Hong Kong and Iceland, combined.

The dead included the parents of a young child who were shot during a robbery in Columbus, Ohio and a young couple killed in their vehicle in the early morning hours near Augusta, Maine.

At least two of the Christmas Day shootings qualified as mass shooting incidents with four or more people shot.

So far this year, there has been an average of roughly 36 gun fatalities and 73 gun injuries each day, according to the Gun Violence Archive.

The majority of Americans say the most important events of 2015 were the mass shootings in the United States, including the attack in San Bernardino, California, according to an Associated Press-Times Square Alliance poll.

On December 2, in the deadliest mass shooting in the US in three years, 14 people were killed and 22 others were injured when two extremists attacked a center for people with developmental disabilities in San Bernardino.

According to the US Centers for Disease Control (CDC), firearms are the cause of death for more than 33,000 people in the United States every year, a number that includes accidental discharge, murder and suicides.
