![]() The biggest difference is that the city of Cincinnati is quite small as they didn’t do all the annexing that Columbus did in the 60s. Cincinnati is 3,800 per square mile and Columbus is 4,000. Animated map of population density in the U.S. Cincinnati and Columbus have nearly the same density. ![]() Currently, the three most populous states in the US are California (39.5m), Texas (28.3m), and Florida (21m).Īt present, the population’s median center continues to move to the southwest slowly (2.57 miles per year). After 100 years, the population of California increased by 504% to 39.9 million. So in 1917, only 3.1 million people lived in California. But over the past century, the distribution of the population in the nation has changed dramatically. Until the 20th century, the eastern states remained the most populous. Throughout the nineteenth century, more than one square mile (1.6 million km2) of land west of the Mississippi River was obtained by the federal government. The map below shows when each state reached its highest point as percentage of the U.S. Populations for intermediate years were interpolated by cubic splines to log-density essentially, that means that it assumes a smooth change in the rate of growth for each county over time. The animated map of population density, made using Jonathan Schroeder’s county-level decadal estimates.

In that time, many deadly diseases evolved in the Old World (smallpox, the plague, measles). The Americas’ peoples had no resistance to Europeans’ diseases because the Americas’ populations had been primarily isolated from Europe. Most of the indigenous tribes of America lived along the rivers and on the coasts of the Atlantic and Pacific oceans. But beginning in the 19th century, archaeology and the research of burials and the material remains of society helped determine native populations before European contact.Īpproximations for North America have ranged from 3.8 million to 18 million. Most indigenous people lived in small communities. ![]() It isn’t easy to evaluate populations in the 15th century in America. Population density map of what is now the United States (1492) But during the country’s history, these numbers haven’t stayed fixed. (1990 – 2017)Īt the moment, about 328 million people are living in the U.S, a nation that’s 9.84 million sq km (3.53 million square miles). Animated map of population density in the U.S.Population density map of what is now the United States (1492).Note: links for each location go to the relevant demography page, when available.Countries and dependencies by population density Unless otherwise noted, areas and populations are sourced from the United Nations World Population Prospects, which uses the latest censuses and official figures, as well as figures from the United Nations Department of Economic and Social Affairs. Thus constituent countries that are not included on ISO 3166-1, and other entities not on ISO 3166-1 like the European Union, are not included. The list does not include entities not on ISO 3166-1, except for states with limited recognition. The figures in the table are based on areas including internal bodies of water such as bays, lakes, reservoirs and rivers. The list also includes unrecognized but de facto independent countries. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. This is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. Population density (people per km 2) by country
