They enjoyed a comfortable childhood and, as it turns out, a coveted summer job: They all landed internships at New York’s City Hall under Mayor Michael R. Bloomberg, according to a list obtained by The New York Times through the Freedom of Information Act.

Of course, it is not unusual for young people with connections to win choice internships in all kinds of workplaces. But the records offer a glimpse inside the social and power circles of the Bloomberg administration, which has accommodated dozens of young people with connections to the mayor’s friends, business associates and government appointees for the prestigious, if unpaid, slots. Take Jacob Doctoroff, whose father, Daniel L. Doctoroff, was deputy mayor and is now the president of Bloomberg L.P. He had an internship in 2002. He was in the eighth grade. “It was either that or going to summer camp,” Jacob Doctoroff said in an interview. Now an undergraduate at Yale, he recalled enjoying his stint at the mayor’s office of management information systems. “I truthfully couldn’t tell you how I got the internship,” he said. “But you’d be working with a bunch of 35- to 45-year-olds, and you didn’t have a sense that you were in an internship program.” The mayor’s office is not eager to share information about who gets the internships and took three months to furnish the list, after the Freedom of Information Act request and repeated follow-up messages. … Career counselors view the appointments, which are primarily summer stints, as plum résumé enhancers, partly because of Mr. Bloomberg’s stature. … Luke Russert, son of Tim Russert, the “Meet the Press” host who died in 2008, worked at City Hall during summer 2007. In an interview, Mr. Russert said that he juggled two internships that summer — one at the mayor’s office, the other at NBC, working for Conan O’Brien.
