Final answer:
Kansas has the highest population density among the listed states, owing to its balance of a relatively higher population and smaller land area.
Step-by-step explanation:
Among the states mentioned, Kansas has the greatest population density. Population density is calculated by dividing the population of a state by its total land area. While none of the states listed are particularly dense compared to regions like the Northeast or states like California or Texas, Kansas, with its combination of relatively higher population and smaller land area compared to its neighboring states, tends to have a higher population density. The urban and suburban areas, particularly around cities such as Wichita and Kansas City, contribute to this density.
