  1. Geographic distribution of pediatricians in the United States : An analysis of the fifty States and Washington, DC.

    Article - En anglais


    To determine current geographic distribution of pediatricians in the United States, to assess the changes in the geographic distribution of pediatricians between 1982 and 1992, and to identify factors associated with the distribution of pediatricians among the 50 states.


    A data set was constructed using several published data sources including the American Medical Association Physician Masterfile as the principal source for physician information.

    The pediatrician-to-child population ratio (PCPR, the number of pediatricians per 100 000 people under 18 years of age) was calculated to compare the distribution of pediatricians among states and the distributional changes between 1982 and 1992.

    Lorenz curves and Gini indices were used to describe distributions and to compare distributions across time periods.

    Linear regression analysis was performed to assess the relationship between PCPR (dependent variable) with 9 predictor variables.


    Between 1982 and 1992, there was a 5.4% increase in the United States (US) child population and a 46.1% increase in the number of pediatricians in patient care.

    During that time period, the PCPR increased by 38.6% from 35.1 per 100 000 to 48.6 per 100 000.

    There was a more than 4-fold difference in the PCPRs of the highest state (Maryland, 84.3) and the lowest state (Idaho, 18.5) in 1992.

    The PCPR increased in all 50 states, but varied from a 4.1% increase in Wyoming to a 63.4% increase in Massachusetts. (...)
