In 2023, Washington, D.C. had the highest population density in the United States, with 11,130.69 people per square mile. As a whole, there were about 94.83 residents per square mile in the U.S., and Alaska was the state with the lowest population density, with 1.29 residents per square mile. The problem of population density Simply put, population density is the population of a country divided by the area of the country. While this can be an interesting measure of how many people live in a country and how large the country is, it does not account for the degree of urbanization, or the share of people who live in urban centers. For example, Russia is the largest country in the world and has a comparatively low population, so its population density is very low. However, much of the country is uninhabited, so cities in Russia are much more densely populated than the rest of the country. Urbanization in the United States While the United States is not very densely populated compared to other countries, its population density has increased significantly over the past few decades. The degree of urbanization has also increased, and well over half of the population lives in urban centers.

Based on land area, Brazil is the largest country in Latin America by far, with a total area of over 8.5 million square kilometers. Argentina follows with almost 2.8 million square kilometers. Cuba, whose surface area extends over almost 111,000 square kilometers, is the Caribbean country with the largest territory.

Brazil: a country with a lot to offer

Brazil's borders reach nearly half of the South American subcontinent, making it the fifth-largest country in the world and the third-largest country in the Western Hemisphere. Along with its landmass, Brazil also boasts the largest population and economy in the region. Although Brasília is the capital, the most significant portion of the country's population is concentrated along its coastline in the cities of São Paulo and Rio de Janeiro.

South America: a region of extreme geographic variation

With the Andes mountain range in the West, the Amazon Rainforest in the East, the Equator in the North, and Cape Horn as the Southern-most continental tip, South America has some of the most diverse climatic and ecological terrains in the world. At its core, its biodiversity can largely be attributed to the Amazon, the world's largest tropical rainforest, and the Amazon river, the world's largest river. However, with this incredible wealth of ecology also comes great responsibility. In the past decade, roughly 80,000 square kilometers of the Brazilian Amazon were destroyed. And, as of late 2019, there were at least 1,000 threatened species in Brazil alone.

The total area of cropland in the United States has not changed significantly over the last several years, with only a slight decrease from 257.4 million acres in 2012 to around 253.7 million acres in 2018. The largest decrease in area during that time period occurred between 2014 and 2015.
Crop Diversity in the United States A significant portion of the United States economy is rooted in agriculture. As a large country with a diverse and varied climate, the United States is perfectly suited to producing a huge variety of crops. For instance, much of the tobacco produced in the United States originates from North Carolina, Kentucky, and Virginia. However, when it comes to fresh vegetables, California had by far the highest production volume of any U.S. state as of 2018. Facts about U.S. Farms As the largest state in the continental United States, Texas also has the highest number of farms of any U.S. state, at 248 thousand in 2018. Missouri came in second place at 95 thousand farms in that year. Operating and maintaining a farm in the United States is labor intensive, with many different costs and expenses that must be considered in order to keep the farm profitable. As of 2017, around 15.3 percent of total farm production expenditure was attributed to animal feed.
