Citations to journal articles per faculty member at Ph.D. granting universities in EPSCoR and non-EPSCoR states between 2011 and 2020.
Citation data were measured as of calendar year 2021; since older articles have had a greater time to collect citations, the chart shows a trend towards lower citations over time from the oldest to the newest articles. EPSCoR mean = 36.7 ±6.85; non-EPSCoR mean = 44.3 ±5.50; p < 0.01.
