The population density of Denmark in 2020 was 135.73 people per square kilometer, a 0.51% increase from 2019. A comparative study of trabecular bone micro-structural measurements using different CT modalities. A higher physiological density suggests that the available agricultural land is They have close to no cropland, people live almost entirely in urban areas or are nomadic herders or fishermen, and national income is used to buy crops on the international market. The US, at number 173 on the list, has one of the world's lowest physiological population densities.
