Adjusted Male and Female Salary Differences by Work Setting, Clinical Specialty, and Job Position From NSSRN 1988-2008

Data are from the National Sample Survey of Registered Nurses (NSSRN). Ordinary least-squares regression was used for the model, which included gender (male, female), age, race (white, nonwhite), marital status (married, divorced or widowed, never married), children at home (yes, no), foreign education (yes, no), education (diploma, associate’s degree, bachelor’s degree, master’s or doctorate degree), hours worked per week, years since graduation, polynomial of second degree and years since graduation, Metropolitan Statistical Area (MSA) (in MSA, not in MSA), state (51 categories), survey year (1988, 1992, 1996, 2000, 2004, 2008), work setting (hospital, ambulatory, other), clinical specialty (orthopedics, medical or surgical, neurology, newborn or pediatrics, chronic care, psychiatry, cardiology, other), job position (staff nurse, advanced clinical nurse, nurse anesthetist, education/research, senior academic, middle management, senior administration, other), and interaction terms of gender with work setting, clinical specialty, job position, and survey year. All continuous variables were mean centered. This model accounted for about half of the variance in salaries (R2 = 0.46). The estimated average salary gap was $5148. Orthopedics was the only nonsignificant clinical specialty. Senior academic was the only nonsignificant job position. Survey weights were applied to make results nationally representative. Salary amounts reflect 2013 dollars and were normalized using the consumer price index. Error bars indicate 95% confidence intervals.
