Violin plots showing the level of importance assigned to each value theme (A–D) by the survey participants, aggregated by LGA context (inner, middle, outer), as well as the entire study area (all LGAs), and showing statistical differences between the 2020 and 2023 survey responses based on the Mann–Whitney U-test. The average (circle), interquartile range (box), median (horizontal line), and overall data distribution is shown. The asterisks indicate a significant p value for the independent Mann–Whitney U-tests: *p < 0.05, **p < 0.01, ***p < 0.001.
