A new study confirms that black men and women are treated differently in the hands of law enforcement. They are more likely to be touched, handcuffed, pushed to the ground or pepper-sprayed by a police officer, even after accounting for how, where and when they encounter the police.

But when it comes to the most lethal form of force — police shootings — the study finds no racial bias.

“It is the most surprising result of my career,” said Roland G. Fryer Jr., the author of the study and a professor of economics at Harvard. The study examined more than 1,000 shootings in 10 major police departments, in Texas, Florida and California.

The result contradicts the mental image of police shootings that many Americans hold in the wake of the killings (some captured on video) of Michael Brown in Ferguson, Mo.; Laquan McDonald in Chicago; Tamir Rice in Cleveland; Walter Scott in South Carolina; Samuel DuBose in Cincinnati; Alton Sterling in Baton Rouge, La.; and Philando Castile in Minnesota.

The study did not say whether the most egregious examples — the kind of killings at the heart of the nation’s debate on police shootings — are free of racial bias. Instead, it examined a much larger pool of shootings, including nonfatal ones. It focused on what happens when police encounters occur, not how often they happen. (There’s a disproportionate number of tense interactions among blacks and the police when shootings could occur, and thus a disproportionate outcome for blacks.) Racial differences in how often police-civilian interactions occur have been shown reflect greater structural problems in society.

Official statistics on police shootings are poor. James Comey, the F.B.I. director, has called the lack of data “embarrassing and ridiculous.” Even when data exists, the conditions under which officers decide to fire their weapons are deeply nuanced and complex.

Mr. Fryer is the youngest African-American to receive tenure at Harvard and the first one to receive a John Bates Clark medal, a prize given to the most promising American economist under 40. He is not afraid of controversial question

He and a group of student researchers spent about 3,000 hours assembling detailed data from police reports in Houston; Austin, Tex.; Dallas; Los Angeles; Orlando, Fla.; Jacksonville, Fla.; and four other counties in Florida.

They examined 1,332 shootings between 2000 and 2015, systematically coding police narratives to answer questions such as: How old was the suspect? How many police officers were at the scene? Were they mostly white? Was the officer at the scene for a robbery, violent activity, a traffic stop or something else? Was it nighttime? Did the officer shoot after being attacked or before a possible attack? One goal was to figure out whether police officers were quicker to fire at black suspects.

In officer-involved shootings in these 10 cities, officers were more likely to fire their weapons without having first been attacked when the suspects were white. Black and white civilians involved in police shootings were equally likely to have been carrying a weapon. Both of these results undercut the idea that the police wield lethal force with racial bias.

But this line of analysis included only encounters in which a shooting took place. A more fundamental question still remained: In the tense moments when a shooting may occur, are police officers more likely to fire if the suspect is black?

To answer this question, Mr. Fryer focused on one city, Houston. The police department there allowed the researchers to look at reports not only for shootings but also for arrests when lethal force might have been justified. Mr. Fryer defined this group to include suspects the police charged with serious offenses like attempting to murder an officer, or evading or resisting arrest. He also considered suspects shocked with Tasers.

And in the arena of “shoot” or “don’t shoot,” Mr. Fryer found that, in tense situations, officers in Houston were about 20 percent less likely to shoot suspects if the suspect were black. This estimate was not very precise, and firmer conclusions would require more data. But, in a variety of models that controlled for different factors and used different definitions of tense situations, Mr. Fryer found that blacks were either less likely to be shot or there was no difference between blacks and whites.
