What is Population Density?
Population density is a measurement of the number of people per unit of land area. It is usually expressed as the number of people per square kilometer or mile. Population density is one of the most important indicators of a country's population size, population growth, socioeconomic development, and the environmental impact of human activities. Population density can also be used to compare different countries and regions.
US Population Density
The population density of the United States is relatively low compared to other countries, with an average of approximately 37.3 people per square kilometer in 2020. However, population density varies greatly between different states and regions. The population densities of some states are higher than the national average, while others are lower. For example, the population density of New York is much higher than the national average, with an average of 394 people per square kilometer in 2020. Conversely, Alaska has the lowest population density of all states, with an average of only 1.3 people per square kilometer.
Most Densely Populated US States
The most densely populated US states in 2020 are New Jersey, Rhode Island, Massachusetts, Connecticut, and Maryland. New Jersey has the highest population density of all states, with an average of 1,210 people per square kilometer in 2020. Rhode Island is the second most densely populated state, with an average of 1,010 people per square kilometer in 2020. Massachusetts is the third most densely populated state, with an average of 880 people per square kilometer in 2020. Connecticut is the fourth most densely populated state, with an average of 740 people per square kilometer in 2020. Maryland is the fifth most densely populated state, with an average of 690 people per square kilometer in 2020.
Least Densely Populated US States
The least densely populated US states in 2020 are Wyoming, Alaska, Montana, North Dakota, and South Dakota. Wyoming has the lowest population density of all states, with an average of only 5.8 people per square kilometer in 2020. Alaska is the second least densely populated state, with an average of only 1.3 people per square kilometer in 2020. Montana is the third least densely populated state, with an average of only 6.4 people per square kilometer in 2020. North Dakota is the fourth least densely populated state, with an average of only 10.9 people per square kilometer in 2020. South Dakota is the fifth least densely populated state, with an average of only 11.3 people per square kilometer in 2020.
Population Density Trends
The population density of the United States has been steadily increasing since the 1950s. The population density of the United States was 33.8 people per square kilometer in 1950, and this increased to 37.3 people per square kilometer in 2020. This increase is mainly due to the growth of urban areas and the movement of people from rural to urban areas. Population density is expected to continue to increase in the future as more people move to
