A heat map of the United States showing entropy contributions for population in 2021. The map uses a color gradient from light beige to dark red to indicate the magnitude of entropy contributions. Darker colors represent higher values, while lighter colors represent lower values. The color scale ranges from 0.1 to 0.6. Notable regions with higher entropy contributions include Nevada and Arizona, which are colored in dark red. Illinois also shows a significant contribution, colored in a darker shade of red. Most other states are in the mid-range, colored in various shades of orange and beige. The map is structured in a grid layout corresponding to the states of the United States.Spatial distribution of entropy contributions for population in the United States (2021)
