Of that number 14,970 were victims of homicide, murder or accidental shootings, compared to 14,789 dead 2018.
The other 23,760 deaths in 2019 were from suicides, the GVA said.
There was no figure from the organization for the number of firearm deaths by suicide in 2018.
There were 409 mass shootings and 30 mass murders in 2019, which GVA defines as incidents in which four or more people were injured or killed.
Such incidents caused around two percent of firearm deaths, with other fatalities resulting from domestic disputes, gang violence, robberies and accidents with firearms.
The GVA report found the regions with the most gun-related deaths during the past year were Louisiana, Mississippi, Florida, Alabama, Georgia and South Carolina, followed by North Carolina, Virginia, West Virginia, Maryland, the District of Columbia, Pennsylvania, Delaware and New York.
It is estimated that in the United States, a country with around 327.2 million inhabitants, there are between 200 million and 350 million firearms in the hands of citizens.
There are no exact figures because there is no national census, federal documentation or public health studies about these weapons.
The GVA is an online archive of gun violence incidents collected from more than 6,500 law enforcement, media, government and commercial sources daily in an effort to provide near-real time data about the results of gun violence.
It is an independent data collection and research group with no affiliation with any advocacy organization.
