Comparison of Rural-Urban Index DIstributions (A) Across the US Population, (B) Wisconsin Population, and (C) UW Health Pancreatic Cancer Registry Patients

Each index is standardized such that the “Rural-Urban Interface” line lies between those values that the index designated as urban (left of line) and rural (right of line). Center points indicate the median of the index, boxes indicate the interquartile range, and spikes indicate the upper- and lower-adjacent values (1.5 times the interquartile range).

^a RUCA(z) is based on 2013 ZCTAs. US and Wisconsin population data are not available at the ZCTA level for 2013; therefore, those distributions are excluded from the Figure.
