These are killer odds.

You’re more likely to die in a plane crash, drown in your bathtub or perish in an earthquake during your lifetime than be murdered by a stranger in New York.

Just 29 victims of the city’s record-low 334 slayings in 2013 did not know their killers, according to NYPD homicide stats.

Murders by strangers are considered a key to assessing the overall safety of a city as they typically result from violent street muggings, store robberies or shootouts that claim the lives of innocent bystanders.

Last year’s figure is down 45 percent from the 53 people killed by strangers in 2012, leaving the odds that a victim was done in by an assailant who was not a friend, family member or acquaintance in 2013 at 1 in 275,000.

Even veteran cops were left stunned.

“That’s unbelievable,” said one senior police official when informed of the numbers.

He said that murders by strangers commonly unfold in stickups at gas stations and bodegas, a crime that once plagued the city but is rapidly disappearing.

“Those are few and far between now,” he said, adding that stores selling cellphones and services have become the top target of armed robbers.

The 29 victims of strangers involve only cases in which cops ID’d the killer, so the final tally could tick up as cops solve more murders.

There were 62 additional victims killed by a family member, including 17 by a spouse, parent or child, and 53 more slain by a friend or acquaintance — a total of 115 during the year. An acquaintance can include a rival gang member, cops said.

That’s down from the 151 non-stranger slayings in 2012, a 24 percent drop, among the 419 homicides that year.

Police solved 152 homicides in 2013, a figure that includes arrests and cases in which police identified a perpetrator who was not charged. The suspects in those closed cases are either dead or already serving life sentences out of state.

The NYPD closed out 214 murders during 2012.

Former Commissioner Ray Kelly attributed the final murder number of 334, the lowest since reliable record-keeping began in 1963, to “Operation Crew Cut,” which targeted trigger-happy youth gangs, and other police initiatives.
