East of the Mississippi River.
The density of seawater in the Mediterranean Sea is generally higher than that of freshwater in the Mississippi River due to its salt content, which increases the mass of the water without significantly increasing its volume. Seawater typically has a density of about 1.025 g/cm³, while the density of freshwater in the Mississippi River is around 1.000 g/cm³. Additionally, factors like temperature and salinity variations can affect the density in both bodies of water, but the Mediterranean's saline nature consistently results in greater density compared to the freshwater of the Mississippi River.
California had the highest immigrant population compared to other states west of the Mississippi River.
The population density of High River is 905.5 people per square kilometer.
The only five states entirely east of the Mississippi River with areas of population density of fewer than two people per square mile are Maine, Vermont, West Virginia, Kentucky, and Mississippi. These states have rural regions with low population densities, often characterized by vast, unpopulated land areas.
