Each fall the Statistical Research Center conducts its Survey of Enrollments and Degrees, which asks all degree-granting physics and astronomy departments in the U.S. to provide information concerning the numbers of students they have enrolled and counts of recent degree recipients. In connection with this survey, the authors ask for the names and contact information for students currently enrolled in their graduate program. Seventy-three percent of the departments provided contact information for their graduate students. The majority of the data in this "focus on" comes from physics and astronomy students who were identified as being new to a department in the academic years 2007-08 and 2009-10. An initial invitation to participate in the survey was sent to the students in April of their first year at a department. According to the findings from the Survey of Enrollments and Degrees, there were 3,069 first-year physics students enrolled in the fall of 2007 and 3,089 in the fall of 2009. Findings reveal that total first-year graduate student enrollments at physics departments have remained at about 3,000 students for the last 6 years. Around 70% of non-U.S. students entering physics departments in the U.S. are from Asia. Almost half of PhD-seeking first-year physics students aspire to work in a university setting.
